Interdependence of productive characteristics of wheat and their influence

U radu su prikazani rezultati perspektivnih genotipova pšenice, gajenih u različitim agroekološkim uslovima, tokom 2013/2014. godine. Analizirane su produktivne osobine i kvalitet zrna, i utvrđene su korelacione veze između njih. Zapaža se da su genotipovi sa nižim prinosom imali bolјi kvalitet zrna i obrnuto. Kao najprinosniji genotip, istakao se KG-60-3/3 (5,6 t ha-1), dok su genotipovi KG-52/3 i KG-47/21 imali najveće proseče vrednosti sedimentacije proteina (43,6 ml i 40,7 ml) i sadržaja vlažnog glutena (36,2% i 35,1%). Uočena je jaka zavisnost između mase zrna po klasu, mase zrna po bilјci i mase 1000 zrna. Ove komponenete prinosa su pozitivno korelisane sa prinosom zrna. Sa druge strane, između prinosa i kvaliteta zrna utvrđena je negativna korelacija, što otežava proces oplemenjivanja u cilјu stvaranja genotipova sa pozitivnom ekspresijom obe osobine.The paper presents the results of perspective wheat genotypes, grown in different agroecological conditions, during 2013/2014. Productive traits and grain quality were analyzed, and correlations between them were established. It is observed that genotypes with lower yield had better grain quality and vice versa. As the most productive genotype, it stood out KG-60-3/3 (5.6 t ha-1), while genotypes KG-52/3 and KG-47/21 had the highest average protein sedimentation values (43.6 ml & 40 .7 ml) and wet gluten content (36.2% & 35.1%). A strong dependence was observed between the mass of grains per ear, the mass of grains per plant and the mass of 1000 grains. These yield components are positively correlated with grain yield. On the other hand, a negative correlation was established between yield and grain quality, which makes the breeding process difficult in order to create genotypes with positive expression of both traits
