AB  - Variability and components of variance for some dry matter status indicators (grain yield, biological yield and grain harvest index) have been studied in 30 winter wheat varieties from different selection centers (Morava, Lepenica, Studenica, Takovcanka, Toplica, Srbijanka, KG 100, Lazarica, Bujna, Matica, Vizija, Pobeda, Rana 5, Evropa 90, Renesansa, Tiha, Mina, Prima, Kremna, Rusija, Pesma, KG - 200/31, KG - 253/4 - 1, KG - 115/4, KG - 165/2, KG - 56/1, KG - 100/97, Perla, KG - 224/98 and KG - 10). The experiment was performed in randomized block design in five replications on the experimental field of Small Grains Research Centre, Kragujevac in three years. Average estimated values for grain yield, biological yield and grain harvest index differed high significantly among years and among varieties. The highest average value for grain yield had KG 10 variety (792.94g m-2) and the lowest value was found in KG 200/31 (303.88g m-2). During investigated period the highest average value for biological yield was determined in KG 10 (1907.62 g m-2), and the lowest value in Pesma (701.55). The grain harvest index varied from 39% (Lepenica, KG 200/31) to 46% (Renesansa, Tiha, KG 100/97). The lowest variability for grain yield was established in Rana 5 variety and the highest in Takovcanka (V = 9.60%; 27.71%, respectively). Coefficient of variation for biological yield varied from 4.02% (Matica) to 28.85% (Evropa 90). The lowest variability for grain harvest index was established in Evropa 90 and the highest in Pesma (V = 5.46%; 23.49%, respectively). Phenotypic analysis of variance indicated that genetic factors had higher impact on the expression of GY and BY than ecological factors. Higher share of ecological variance was registered at variability of GHI.

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.
