AB  - Sunflower line with resistance for downy mildew (Ha-26R) and susceptible line (Ha-26S) were inoculated with the suspension of Plasmopara halstedii zoosporangia, race 730, in the phase of first pair of leaves. The expression of defense related genes was investigated in the time period of 2 to 96 h after treatment. Several categories of defense-related genes: signalization (EDS1 and EDR1); H2O2 producing (Hacaox and Haoxox); antioxidative response (SODc and SODp), pathogenesis related (chi, PAL, PR5) were examined. Most examined defense related genes were constitutive with higher expression in resistant line. However, in response to secondary downy mildew infection six genes were upregulated. Upregulation of HaEDS1 signaling gene 2 h after infection indicates that SA mediated response is activated. Pathogenesis related genes: chitinase and PR5, were also upregulated in the earliest time point. Other defense related genes: SODp, Caox and OxOx were sequentially upregulated from 4 to 48 h after infection in resistant line. Our results indicate that the early response of defense related genes to secondary downy mildew infection, resembles to hypersensitive-like reaction and is connected with resistance conferred by Pl6 gene. According to our results resistance to secondary infection is characterized with earlier upregulation of PR5 in comparison to primary infection.

AB  - For much of the past century, mutagenesis has gained popularity in plant genetics research as a means of inducing novel genetic variation. Induced mutations have been applied for the past 40 years to produce mutant cultivars in sunflower by changing plant characteristics that significantly increase plant yield and quality. The present study is focused on generating baseline data to elucidate the role of genotypic differences in the response of sunflower to induced mutagenesis with the aim of expanding the applicability of the use of induced mutant stocks in the genetic improvement of the crop and in its functional genomics. The strategy adopted was to estimate the optimal treatment conditions (doses of mutagens) through relating the extent of damage in seedling progeny to the exposure levels of the initiating propagates to mutagens. Seeds of fifteen elite sunflower genotypes of commonly used as breeding stocks and grown on commercial scales were treated with a range of mutagens: gamma rays (γ rays); fast neutrons and with ethyl-methane-sulphonate (EMS) at different treatment doses. The three mutagenic agents affected seedling height, reducing it with increasing dosage. Based on the mutagen damage on seedling height, the 50% and 30% damage indices (D50 and D30, respectively) were estimated for the 15 sunflower genotypes for the three mutagens. The D50 (D30) values for the sunflower lines ranged from 120 to 325 Gy (5 to 207 Gy) for gamma irradiation; 9 to 21 Gy (0.1 to 10 Gy) for fast neutrons and 0.69 to 1.55% (0.01 to 0.68%) concentration of EMS.

AB  - An experiment was conducted at Rimski Šančevi Experiment Field of Institute of Field and Vegetable Crops in Novi Sad during 2000 - 2005. The soil in the experimental plot was calcareous chernozem on loess terrace. Using the yield response factor (ky), the study investigated how sunflower yield and evapotranspiration were affected by deficit of available soil water during the growing season. The experiment consisted of an irrigated treatment (T1), in which irrigation was used when soil moisture levels dropped to 60-65% of FC (field capacity), and a nonirrigated control treatment (T0). The sunflower hybrid used in the study was NS-H-111. On average, no significant differences in yield level were observed between T1 (3.79 t ha-1) and T0 (3.75 t ha-1) treatments. Seasonal evapotranspiration (ETm) obtained in T1 treatment was in the 402-479 mm range. The yield response factor (ky) was obtained as 0.20 for total growing season and 0.27, 0.31 and 0.48 for vegetative, flowering and yield formation period, respectively. Period from flowering to maturity was the most sensitive towards water deficiency.
