AB  - Tomato, one of the most produced vegetables in the world, is experiencing continuous
global increase in both production and consumption. Fruit quality traits are important for
fresh market tomatoes as well as for the processing industry. Despite the growing demand
for both fresh and processed tomatoes, consumers are not satisfied with the quality of
available fruits. The main objectives of the present work were to determine the
physicochemical characteristics [pH, total soluble solids (TSS), total titratable acids
(TTA), TSS/TTA ratio, DMC, lycopene, β-carotene, vitamin C, and total phenolic
content], as well as the antioxidant activity of 13 different tomato lines, and to identify the
most promising ones in terms of fruit taste and quality. Antioxidant activity was
determined using the ABTS and DPPH methods with Trolox used as the standard
compound. PCA analysis was conducted to identify group patterns. The results of PCA
analysis indicated a specific genotypic response in all investigated physicochemical traits.
Genotypes 2, 10, and 13 were identified as the best for fresh consumption, as they
exhibited the highest levels of compounds crucial for good taste, nutrition, and human
health benefits. The most promising genotype related to fruit quality attributes was
genotype 10 with the best TSS and TAA content and TSS/TAA ratio, which is important
for overall taste perception. On the other hand, genotype 9 showed promise for industrial
purposes due to its ideal pH value in the juice and good soluble solid content. High
antioxidant activity was characteristic of genotypes 1 and 2, and their consumption as fresh
tomatoes can be beneficial to human health. They also should be considered for further
evaluation as potentially interesting genotypes for abiotic stress research and selection
programs which can lead to the development of both superior fruit quality and stress
tolerant genotypes.

AB  - Significant genotype x environment interaction for quantitative traits, such is grain yield, reduces the usefulness of genotype means, over all environments, for selecting superior genotypes. AMMI model is a valuable statistical tool in identifying systemic variation contained in the interaction effect. Obtained data could be applied in maximizing yield potential in every environment based on both narrow and wide genotype adaptability, without the necessity of developing breeding programs for smaller targeted environments. Precise assortment of superior genotypes, with the assistance of AMMI model, leads to the better recommendation of newly bred hybrids, and thus increasing maize grain yield in a targeted environment. In this research genotype x environment interaction and yield stability of 36 maize hybrids of FAO 300-700 maturity group was investigating. The trial was set according to Randomized Complete Block Design (RCBD). Data were processed in order to obtain average estimates of grain yield, and yield stability was assessed by the method of AMMI analysis. The highest average grain yield was achieved in 2011 (11.62 t/ha), and the lowest in the most stressful and dry 2012 (6.90 t/ha). In the region Loznica L2 the highest average yield was noticed (13.81 t/ha), while at L7 (Sremska Mitrovica) average grain yield was the lowest (6.97 t/ha). Results of AMMI analysis gave precise recommendation for production of maize hybrids in certain environments, by determining winning areas of hybrids H20, H11 and H36. Medium early maturing and high yielding hybrids (H11 and H20) are therefore considered more favorable for production in environments with lower precipitation, while high yielding and more stable hybrids H21 and H35 are suitable for a wider range of environments. Hybrid H36 (FAO 700) showed its full potential at L2, and L3 which did not suffer from a lack of moisture. This hybrid also expressed its best potential in environments with favorable conditions.

AB  - The success in growing agricultural plants depends on genotype grown, environment and growing technology applied. The impacts of these factors should not be studied separately. Interaction among genotypes and environment was crucial for breeding work and improvement of variety characteristics. Very often in production practice it happens that when comparing the same varieties in different soil and weather conditions they are ranked differently. One of the key aims set at the breeders is breeding for the traits of wide adaptability and calculating of the complex components of genetic variance which is the main condition for successful breeding program such as breeding for increased yield and yield components. Trial was set up at random block system in five repetitions. Ten onion genotypes from the Institute for Vegetable Crops germplasm were used in this trial. After choosing the most stabile genotypes, they were crossed by applying full diallel without reciprocals. Then, a field trial was set up with parents and hybrids of F-1 and F-2 generation. The experiment has been set up at the trial field of the Institute for Vegetable Crops in Smederevska Palanka, for three years. The best adaptability in the experiment, for mass of the onion bulb had genotypes Makoi bronzi and Holandski zuti, while for average yield, it was Jasenicki crveni. Also, components of genetic variance in both progeny generations were calculated for mass, yield and height of fresh bulb. The most common heredity mode for mass and yield of the bulb was super-domination and domination of a better parent.

AB  - In this paper was compared average fruit and seed yields of different varieties grown on the vertisol belonging to five species of the family Cucurbitaceae (melon, watermelon, summer squash, winter squash, butternut squah) based on the two-year data (2010 and 2011). Five genotypes of melon (Sezam, Cerovaca, Galia, Charentais, Ananas), five genotypes of watermelon (Crimson sweet, Top gun, Greybelle, Fantasy, Rosa), five genotypes of summer squash (Ezra, Opal, Beogradska, Fina, Romanesco), three genotypes of winter squash (Sedef, Domaća bela, Plovdivska siva) and two genotypes of butternut squash (Nektar, L2706) were used. The experiment was set up in Smederevska Palanka. After the production of seedlings in the greenhouse of the Institute for vegetable crops, plants were transfered and planted in the open field. Two characteristics were observed: fruit yield per hectare and seed yield per hectare. The main objective of this study was to identify the genotypes which could be recommended for the production on vertisol. Very significant differences of fruit and seed yield per hectare were found between the genotypes and years for melon, watermelon, summer squash and winter squash. The highest average fruit yield was recorded for genotypes: Cerovaca (melon), Fantasy (watermelon), Fina (summer squash), Plovdivska siva (winter squash) and L2706 (butternut squash).

AB  - The present study was conducted in order to analyze the divergence of the fourteen native populations of St. John’s wort (Hypericum perforatum L.) originating from different locations of Serbia based on six leaf morphological characteristics including leaf length and width, leaf area, leaf length/width ratio and light and dark gland density on leaves. Plants were grown under the same ex situ conditions, along with the standard cultivar ‘Maya’, used as control. The one way analysis of variance (ANOVA) revealed highly significant differences (p lt 0.01) among investigated populations of H. perforatum in all studied characteristics. The highest morphological heterogeneity within populations was observed in the leaf light gland density (CV = 9.71 - 47.81%) and was followed by leaf dark gland density (CV = 12.94 - 42.19%). These characteristics are considered as important morphological markers, indicating thereby the relative extent of biologically active substances present in the analyzed genotypes of this species, without the need of chemical estimation. The noted morphological variation in H. perforatum probably had a genetic character as all plants had grown under uniform conditions. One can therefore expect that wild populations of H. perforatum are potentially important sources of genetic variation that could be utilized in breeding programs for an improvement of cultivated material and/or selection of new cultivars. Based on the results of UPGMA cluster analysis a group of genotypes of H. perforatum are distinguished from others by higher leaf gland density and presumably higher contents of the biologically active substances if compared with the cv.’Maya’ and hence could be considered in the future breeding programs.
AB  - U radu je analizirana divergentnost četrnaest autohtonih populacija kantariona (Hypericum perforatum L.) poreklom sa različitih lokaliteta u Srbiji u odnosu na šest morfoloških osobina lista: dužinu i širinu lista, odnos dužine i širine lista, lisnu površinu i gustinu providnih i tamnih žlezda na listovima.

abstract = "The present study was conducted in order to analyze the divergence of the fourteen native populations of St. John’s wort (Hypericum perforatum L.) originating from different locations of Serbia based on six leaf morphological characteristics including leaf length and width, leaf area, leaf length/width ratio and light and dark gland density on leaves. Plants were grown under the same ex situ conditions, along with the standard cultivar ‘Maya’, used as control. The one way analysis of variance (ANOVA) revealed highly significant differences (p lt 0.01) among investigated populations of H. perforatum in all studied characteristics. The highest morphological heterogeneity within populations was observed in the leaf light gland density (CV = 9.71 - 47.81%) and was followed by leaf dark gland density (CV = 12.94 - 42.19%). These characteristics are considered as important morphological markers, indicating thereby the relative extent of biologically active substances present in the analyzed genotypes of this species, without the need of chemical estimation. The noted morphological variation in H. perforatum probably had a genetic character as all plants had grown under uniform conditions. One can therefore expect that wild populations of H. perforatum are potentially important sources of genetic variation that could be utilized in breeding programs for an improvement of cultivated material and/or selection of new cultivars. Based on the results of UPGMA cluster analysis a group of genotypes of H. perforatum are distinguished from others by higher leaf gland density and presumably higher contents of the biologically active substances if compared with the cv.’Maya’ and hence could be considered in the future breeding programs., U radu je analizirana divergentnost četrnaest autohtonih populacija kantariona (Hypericum perforatum L.) poreklom sa različitih lokaliteta u Srbiji u odnosu na šest morfoloških osobina lista: dužinu i širinu lista, odnos dužine i širine lista, lisnu površinu i gustinu providnih i tamnih žlezda na listovima. Genotipovi su gajeni u istimex situ uslovima zajedno sa standardnom sortom Maja, korišćenom kao kontrola.

AB  - In this paper was studied effect of commercial organic fertilizers on the yield per plant of melon and watermelon genotypes based on the two- year data (2011 and 2012). Five genotypes of melon (Fiata, Cerovača, Galia, Charentais, Passport) and five genotypes of watermelon (Crimson Sweet, Fairfax, Greybelle, Domestic, Dunay) were selected from the collection of the Institute for vegetable crops from Smederevska Palanka. After plants were planted in the open field fertilization of each genotype with 4 commercial organic fertilizer: Italpollina, DCM Ekomix, Guanitto and Duetto was performed. NPK fertilizer was used as control. The main objective of this study was to determine the genotypes of melon and watermelon which could be recommended and introduced into organic farminf system. Also, one of the aims was to compare the yield per plant of melon and watermelon in organic and conventional farming system. Very significant differences of yield per plant were found between the genotypes, years, treatment and their interaction, both for melon and watermelon. For melon genotype Charentais was determined the strongest effect of commercial organic fertilizers. DCM Ekomix had a negative effect on yield per plant for all genotypes of watermelon. In the melon production, it is possible to achieve higher yields per plant using commercial organic fertilizers compared to inorganic fertilizers.
AB  - Efekat primene komercijalnih organskih đubriva na prinos genotipova dinje i lubenice je ispitivan na osnovu podataka dvogodišnjeg ogleda (2011 i 2012). Iz kolekcije Instituta za povrtarstvo u Smederevskoj Palanci je uzeto 5 genotipova dinje (Fiata, Cerovača, Galia, Charentais, Passport) i 5 genotipova lubenice (Crimson sweet, Fairfax, Greybelle, Domaća, Dunay). Nakon rasađivanja izvršena je prihrana svakog genotipa sa 4 komercijalna organska đubriva: Italpollina, DCM Ekomix, Guanitto i Duetto. Kao kontrola je korišćeno đubrivo NPK. Osnovni cilj rada je bio da se odrede genotipovi dinje i lubenice koji bi mogli da se preporuče za proizvodnju u organskom sistemu gajenja. Takođe, jedan od ciljeva je bio da se uporede prinosi po biljci dinje i lubenice u organskom i konvencionalnom sistemu gajenja. Utvrđene su veoma značajne razlike prinosa po biljci između posmatranih genotipova, godina, tretmana i interakcija i kod dinje i kod lubenice. Kod genotipa dinje Charentais je utvrđen najveći uticaj komercijalnih organskih đubriva. DCM Ekomix je imao negativan uticaj na prinos po biljci kod svih posmatranih genotipova lubenice. Gajenjem dinje uz primenu komercijalnih organskih đubriva je moguće ostvariti veće prinose po biljci u odnosu na primenu neorganskih mineralnih đubriva.

AB  - Investigation comprised 41 tomato genotypes originating from the population of domestic and domesticated genotypes collected in Serbia and belonging to the tomato collection of the Institute of Vegetable Crop Science, Smederevska Palanka. The aim of collection screening was to choose the genotypes tolerant to drought during plant intensive growth stage, whereby the process of selection would set out to obtain the recombinant genotypes for this abiotic factor. The screening criteria were established for genotype divergence in plant height and shoot-root ratio under conditions of optimal irrigation regime and drought. Divergence was estimated using cluster analysis with Euclidean distance as a measure of distance, with a complete gene attachment to grouping. Drought tolerance is expressed by the stress susceptibility index (SSI). Various results were obtained based on the screening of genotypes grown under optimal and dry conditions. As a measure of stress susceptibility, based on SSI, genotypes having different drought tolerance level were determined. On the grounds of the analyses carried out, 10 genotypes were segregated (G102, G104, G107, G109, G110, G119, G125, G126, G128 and G141) to represent a basis to obtain the recombinant genotypes and to initiate the selection for drought resistance.

AB  - Seven traits related to flowering and sex expression in melon were studied and their reaction to application of two growth regulators (ethrel and gibberellic acid) was observed. Four monoecious genotypes (Sesame, ED-3, ED-4, Pobeditel) and four andromonoecious genotypes (Chinese muskmelon, Anannas, Fiata, A2-3lb) had been used for experiments. According to the results, ethrel had higher effects on the investigated traits than gibberellic acid. Ethrel increased the number of perfect flowers per plant for 7.18 (31.42%), reduced the number of male flowers per plant for 21.47 (17.98%), affected earlier appearance of the first pistillate/perfect flower for 3.68 days, and delayed the appearance of the first staminate flower for 16.07 days. Changes in the last two traits caused an extension of the period from the emergence of the first pistillate/perfect to the first staminate flower from 0.1 to 21.57 days, which represents the strongest effect of ethrel. Gibberellic acid had generally opposite effects on the studied traits.

AB  - In this paper was studied stability of early, medium and late melon genotypes grown in greenhouses and in the open field through analysis of interaction genotype x environment (GEI). The main objective of this study was to determine the most stable melon genotype. Experiments in open field and in greenhouse were conducted at the Institute for Vegetable Crops in Smederevska Palanka, during 2010, and 2011. The yield per plant in nine melon genotypes was examined. The values of the principal components of genotypes and environments and GEI were calculated and analyzed using AMMI analysis. This is the first time that in our country someone uses this method to assess the stability of melon genotypes. It was found that genotypes that mature earlier have a higher yield per plant when grown in an open field while late genotypes had higher yield per plant when grown in a greenhouse.

Osnovni cilj rada je bio da se odredi koji genotip dinje je najstabilniji.

Pri analizi podataka korišćena je AMMI analiza, na osnovu koje su dobijene glavne komponente genotipova i sredina, odnosno interakcije GxE. Ovo je prvi put u našoj zemlji da se koristi ovaj metod u oceni stabilnosti genotipova dinje. Utvrđeno je da genotipovi dinje koji ranije sazrevaju imaju veći prinos po biljci ukoliko se gaje na otvorenom polju, dok kasnostasni genotipovi daju veći prinos po biljci ukoliko se gaje u staklenoj bašti.

AB  - The seed of the head cabbage (Brassica oleracea var. capitata L.) in the continental climate is produced by bringing the plants into a certain stage of vegetative development, in meteorological conditions, in which the vernalization is possible. The vernalization is a physiological process of transformation of vegetative meristem tissue to reproductive, skipping in that way one phase of organogenesis - the head. This process takes place in conditions of prolonged exposure to low positive temperatures (winter and autumn in Serbia). Only certain number of plants during the cold period survives this transformation. The experiment was set up in four replications in three sowing dates: August 15th, September 1st and September 15th, with late genotype B at the Institute for Vegetable Crops in Smederevska Palanka. The nursery was planted on October 20th 2010 in vegetative space 70 x 50 cm or 28,500 plants ha(-1). The plants were treated two times with GA(3) in concentration 300 ppm, before and at the end of optimal temperatures for vernalization. The experiment proved the statistical significance of sowing terms to seed yield (P  lt = 0,05) as well as the impact of interaction of sowing and the treatments to percentage of flourishing plants at both levels of significance (P  lt = 0,01 and P  lt = 0,05). The percentage of flourished plants was between minimal 35% and maximal 80%. The seed yield varied significantly from 194 kg to 1224 kg ha(-1).

AB  - One of important onion bulb quality parameter is the number of closed and open juicy leaves in the bulb. The subject of this study was the comparison of F-1 and F-2 hybrids obtained from 5 genotypes of a different geographical origin. The method of full diallel without reciprocals has been applied in order to compare F-1 and F-2 progenies. Open field trial including parents and hybrids of F-1 and F-2 generation has been set up in a random block system, with five replications, at the Institute for Vegetable Crops, Smederevska Palanka, Serbia. The most common mode of inheritance for closed layers in the bulb was intermediary and for open layers in the bulb dominance. The additive component was lower than dominant for both analyzed traits and generation levels (F-1 and F-2), which proves that reaction of dominant genes has been more important for inheritance of these traits. Significant heterosis (26.49%) has been found for the number of open layers in the bulb. Three lines had significant values for general combining ability (GCA). Specific combining ability (SCA) values for three F-1 hybrids were significant for total number of closed layers in the bulb. As for the total number of open juicy leaves, significant values for GCA and SCA were found for one line and for one hybrid combination, respectively.

AB  - Exogenous application of plant hormones affects changes in number, type and percentage of different flower types in melon. The effect of hormones to transform perfect flowers into staminate or pistillate flowers can be used in the production of F1 hybrid seeds of melon. The influence of three plant hormones (ethrel, silver nitrate, and gibberellic acid) on the flowers of five andromonoecious melon cultivars (Chinese muskmelon, Anannas, Fiata, Honeydew and A2-3lb) was evaluated in this study. The used melon varieties had separated perfect and staminate flowers. Experiments were carried out in 2010 and 2011 at the Institute for Vegetable Crops in Smederevska Palanka. Effect of hormones was observed on five traits: 1) number of perfect flowers per plant, 2) number of staminate flowers per plant, 3) the total number of flowers (perfect and staminate) per plant, 4) percentage of perfect flowers per plant, and 5) percentage of staminate flowers per plant. Of the used hormones, the strongest influence on the investigated traits had shown ethrel by increasing the number of perfect flowers per plant for 6.2 and reducing the number of male flowers per plant for 22.0, what represents change of 6.67% compared to the control. Perfect flowers after treatment with ethrel had deformed anthers and they were self-sterile, i.e. suitable for hybridization with pollen from other flowers. In relation to the ethrel, treatments with two other hormones, gibberellic acid and silver nitrate, had weaker and opposite effect on the observed melon traits.
AB  - Egzogeni tretman biljnim hormonima deluje na promene broja, tipa cvetova i njihovog odnosa kod dinje. Efekat hormona da prevodi hermafroditne cvetove u jednopolne može se iskoristiti u proizvodnji semena F1 hibrida dinje. U ovom radu ispitano je dejstvo tri biljna hormona (etrel, srebro nitrat i giberelinska kiselina) na cvetove pet andromonoecijskih sorti dinje (Kineska muskatna, Ananas, Fiata, Medna rosa i A2-3lb). Te sorte imaju razdvojene hermafroditne i muške cvetove. Ogledi su izvedeni tokom 2010. i 2011. godine u Institutu za povrtarstvo, u Smederevskoj Palanci. Praćeno je dejstvo hormona na sledećih pet osobina: 1) broj hermafroditnih cvetova po biljci, 2) broj muških cvetova po biljci, 3) ukupan broj cvetova (hermafroditnih i muških) po biljci, 4) % hermafroditnih cvetova na biljci i 5) % muških cvetova na biljci. Od korišćenih hormona, najjači uticaj na ispitivane osobine ispoljio je etrel koji je povećao broj hermafroditnih cvetova po biljci za 6,2 i smanjio broj muških cvetova po biljci za 22,0, što predstavlja promenu njihovog učešća za 6,67% u odnosu na kontrolu. Hermafroditni cvetovi posle tretmana etrelom imali su deformisane antere i bili su autosterilni, odnosno pogodni za hibridizaciju polenom iz drugih cvetova. U odnosu na etrel, tretmani hormonima giberelinskom kiselinom i srebro nitratom imali su slabiji efekat koji je imao suprotno dejstvo na posmatrane osobine dinje.

In relation to the ethrel, treatments with two other hormones, gibberellic acid and silver nitrate, had weaker and opposite effect on the observed melon traits., Egzogeni tretman biljnim hormonima deluje na promene broja, tipa cvetova i njihovog odnosa kod dinje. Efekat hormona da prevodi hermafroditne cvetove u jednopolne može se iskoristiti u proizvodnji semena F1 hibrida dinje. U ovom radu ispitano je dejstvo tri biljna hormona (etrel, srebro nitrat i giberelinska kiselina) na cvetove pet andromonoecijskih sorti dinje (Kineska muskatna, Ananas, Fiata, Medna rosa i A2-3lb). Te sorte imaju razdvojene hermafroditne i muške cvetove. Ogledi su izvedeni tokom 2010. i 2011. godine u Institutu za povrtarstvo, u Smederevskoj Palanci. Praćeno je dejstvo hormona na sledećih pet osobina: 1) broj hermafroditnih cvetova po biljci, 2) broj muških cvetova po biljci, 3) ukupan broj cvetova (hermafroditnih i muških) po biljci, 4) % hermafroditnih cvetova na biljci i 5) % muških cvetova na biljci. Od korišćenih hormona, najjači uticaj na ispitivane osobine ispoljio je etrel koji je povećao broj hermafroditnih cvetova po biljci za 6,2 i smanjio broj muških cvetova po biljci za 22,0, što predstavlja promenu njihovog učešća za 6,67% u odnosu na kontrolu. Hermafroditni cvetovi posle tretmana etrelom imali su deformisane antere i bili su autosterilni, odnosno pogodni za hibridizaciju polenom iz drugih cvetova. U odnosu na etrel, tretmani hormonima giberelinskom kiselinom i srebro nitratom imali su slabiji efekat koji je imao suprotno dejstvo na posmatrane osobine dinje.",

AB  - In this study, eight melon genotypes belonging to two groups of cultivars according to flowering type (monoecious and andromonoecious) were treated with the plant growth regulator ethrel with the aim to induce the modification of their sex expression. Experiments with treated and control plants were set up in the fields of the Institute for Vegetable Crops at Smederevska Palanka, Serbia, during two years (2010 and 2011). Effects of ethrel were observed on three traits in individual plants: 1) total number of flowers, 2) the percentage of pistillate and perfect flowers and 3) the percentage of staminate flowers per plant. Results showed that exogenous application of ethrel affected decreasing of the total number of flowers, as well as, the change in frequency of flower types within individual melon plants. Ethrel stimulated the formation of pistillate and perfect flowers followed by the deformation of anthers within the perfect flowers. Additionally, ethrel affected decreasing of percentage of staminate flowers in all eight studied melon genotypes. These results are important for the improvement of the F1 melon hybrid seed production in Serbia. It was found that simple spraying of young melon plants with ethrel, eliminated the need for emasculation of flowers in mother plants in crosses.
AB  - U ovom radu, osam genotipova dinje koje pripadaju dvema grupama sorti prema tipu cvetanja (monoecijskim i andromonoecijskim) je tretirano etrelom u cilju indukovanja modifikacija u ekspresiji pola. Ogledi sa tretiranim i kontrolnim biljkama postavljeni su na poljima Instituta za povrtarstvo u Smederevskoj Palanci, Srbija, tokom dve godine (2010. i 2011). Efekat etrela posmatran je na tri svojstva individualnih biljaka: 1) ukupan broj cvetova, 2) procenat ženskih i hermafroditnih cvetova i 3) procenat muških cvetova. Rezultati su pokazali da primena etrela izaziva smanjenje ukupnog broja cvetova, kao i promene u zastupljenosti tipova cvetova kod individualnih biljaka dinje. Etrel je stimulisao formiranje ženskih i hermafroditnih cvetova, uz deformisanje antera unutar hermafroditnih cvetova. Takođe, etrel je uticao na smanjenje učešća muških cvetova kod svih osam proučavanih genotipova dinje. Ovi rezultati značajni su za unapređenje proizvodnje semena F1 hibrida dinje u Srbiji. Utvrđeno je da obično prskanje mladih biljčica dinje etrelom, eliminiše potrebu za emaskulacijom cvetova majčinskih biljaka u ukrštanjima.

AB  - The aim of this study was to examine the effect of five liquid/soluble fertilizers on yield and yield contributing characters in plastic house grown lettuce. Bioactiv, Hascon M-10 AD and Herbagreen were splashed onto the plants; Foliacon 22 was applied within watering and Drin was used in both ways. The yield was significantly increased by all treatments, except for Bioactiv. Considering both the yield and other traits analyzed, the best results have been achieved by application of Drin within watering and it could be recommended for plastic house grown winter lettuce.
AB  - Cilj ovog istraživanja bilo je ispitivanje uticaja pet tečnih i lako rastvorljivih sredstava za ishranu biljaka na prinos i svojstva u vezi sa prinosom kod zelene salate gajene u zaštićenom prostoru u toku zime. Bioactiv, Hascon M-10 AD i Herbagreen primenjeni su folijarno; Foliacon 22 je zalivanjem a Drin je korišćen na oba načina. Zabeleženi su značajno viši prinosi po biljci na svim ispitivanim tretmanima, izuzev na tretmanu Bioactiv. Uzevši u obzir prinos i druga ispitivana svojstva najbolji rezultati su postignuti primenom preparata Drin zalivanjem, te bi se ovaj tretman mogao preporučiti kod plasteničke proizvodnje zelene salate u toku zime.

AB  - Tomato yield depends on two components viz., fruit weight and number of fruit per flower branch. These traits are quantitative and therefore influenced by multiple genes. The objective of this study was to estimate the main gene effects ( additive, dominant and digenic epistasis) and to determine the mode of inheritance for yield components and yield in three tomato cross combinations by generation mean analysis. The trial included genotypes differing in morphology and yield: line DAT, cultivar SP-109 and local population KGZ. The analyzed genotypes belong to tomato germplasm collection of the Institute for Vegetable Crops, Smederevska Palanka, Serbia. Six families per hybrid, including parents, have been tested. Besides, the additive and dominance gene effects, non-allelic gene interactions have been detected for yield components and yield. Duplicate type of epistasis was confirmed for fruit weight and yield in all cases characterized by significant dominance and dominance/dominance effects, which diminishes the effect of dominant genes and makes breeding for yield increase more difficult. Therefore, number of fruits per flower branch increase would be the most efficient strategy for increasing tomato yielding ability.
