AB  - Considering the very important role of nitrogen in plant life cycle, parameters of plant nitrogen nutrition efficiency represent a group of physiological traits suitable to contemporary wheat breeding aims. Therefore, the objectives of the study were to estimate variability of nitrogen nutrition efficiency indicators and to estimate their heritability in wheat. The experiment included 30 wheat cultivars and experimental lines, originating from Serbia: Small Grains Research Center and Institute of Field and Vegetable Crops, Novi Sad. The variability and broad - sense heritability of total nitrogen accumulation (ANt) at maturity, grain harvest index (GIII) and physiological efficiency of nitrogen (PEN) were analysed. The years when the researches were carried out had a highly significant effect on all tested indicators, as well as genotype and interaction year x genotype. Total nitrogen accumulation in mature plant was the most variable indicator (Cv 13.91%), while lower variability was registered for nitrogen harvest index and physiological efficiency of nitrogen (5.81% and 5.59% respectively). NHI heritability was lower (0.52) compared to the ANt and PEN (0.66 and 0.69, respectively). On the other hand, heritability of ANt and PEN were almost the same, but PEN was more repeatable than the ANt.

AB  - The topic of N wheat nutrition was prevalent during the last decades of the 20th century for many reasons such as energy crises, profitability of small grain production, and ecosystem protection and preservation. The objective of this study was to determine the interrelationships between wheat (Triticum aestivum L.) grain N content and other indicators of N nutrition efficiency to better understand the N nutrition process in wheat plants. The experiment included 30 wheat cultivars and experimental lines from Serbia. Plant samples of each genotype were taken at anthesis and maturity. The following parameters related to N accumulation and translocation within the wheat plant were calculated: N content (at anthesis, grain, straw, and total at maturity), N harvest index (NHI), N reutilization (N reU), and N lost (-) or gained (N post-anthesis). Our results showed that N content in the aboveground part of the plant expressed very strong direct positive effects on N yield (phenotypic coefficient 3.78** to 9.34** and genotypic coefficient 1.43** to 2.32**), while its indirect effects varied. The influence of independent variables on grain N content has been changing from year to year in a negative way. Total N accumulation (N total) had the highest negative direct effect in the first year of the study (phenotypic coefficient -2.11**), N total in the second (phenotypic coefficient -2.78**), and N reutilization in the third (phenotypic coefficient -8.49**). Genotypic coefficients indicate that the most frequent strong direct negative effect was N reutilization (-0.47** and -0.99** in the first 2 yr of research, respectively). Nitrogen reutilization and its current assimilation are very important and related to grain N supply processes. Their interaction leads to the conclusion that forming N yield is a very complex mechanism and, as a result, grain yield and quality. The abovementioned parameters could be considered as important criteria in wheat breeding to improve production efficiency and reduce adverse impacts of N fertilizers on the ecosystem.

AB  - This paper deals with interrelationship between grain yield and some physiological parameters of wheat plant nitrogen nutrition efficiency as well as interrelationships between these parameters and some yield related traits (biological yield, grain harvest index). The aim of such investigation is to affirm possibilities of using physiological parameters of wheat plant nitrogen nutrition efficiency as criterions in breeding on its grain yield. The investigation, conducted as three years field trials, included 30 wheat cultivars and perspective lines. There were studied: nitrogen content in the above - ground part of plant at anthesis, in grain, in straw and total nitrogen content at maturity, nitrogen harvest index, nitrogen reutilization, post - anthesis nitrogen accumulation and physiological efficiency of nitrogen. The positive and statistically high significant relationships between nitrogen content in the above - ground part of plant at anthesis, in grain and in straw, total nitrogen content at maturity, nitrogen reutilization and post - anthesis accumulation as physiological parameters and grain yield were registered in investigated material. Most of listed parameters, important by grain yield aspect, can be studied easily and measured before wheat vegetative period ends. The investigated parameters can be recommended as criterions for selecting of parental pairs and evaluating progeny in breeding of wheat on grain yield, considering to their determined interrelationships and their measurability.
AB  - U radu je razmatrana mogućnost korišćenja fizioloških parametara, koji se odnose na efikasnost ishrane pšenice azotom, kao kriterijuma u oplemenjivanju na prinos zrna, na osnovu njihove međuzavisnosti i uticaja na neke osobine povezane sa prinosom zrna pšenice (biološki prinos, žetveni indeks zrna). Istraživanje je izvedeno kao trogodišnji poljski ogled i uključivalo je 30 sorti i perspektivnih linija pšenice. Od fizioloških parametara proučavani su: sadržaj azota u nadzemnom delu biljke u cvetanju, sadržaj azota u zrnu i slami, ukupni sadržaj azota u zreloj biljci, žetveni indeks azota, reutilizacija i prirast azota i fiziološka efikasnost azota. Utvrđena je pozitivna i statistički visoko značajna korelacija između prinosa zrna i skoro svih ispitivanih fizioloških parametara: sadržaja azota u biljci, u cvetanju, zrnu, slami, ukupnog sadržaja azota u zreloj biljci, reutilizacije i prirasta azota. Imajući to u vidu, kao i njihovu merljivost i jednostavnost u izračunavanju, navedeni fiziološki parametri mogu se preporučiti kao kriterijumi za odabir roditeljskih parova i ocenu potomstava u oplemenjivanju pšenice na prinos zrna.
