INFLUENCE OF GENOTYPE AND YEAR ON WINTER WHEAT GRAIN YIELD

Abstract

During three growing seasons (2019-2022), an experiment was carried out in cooperation with the Požarevac Agricultural Expert Service in Požarevac with 6 varieties of wheat in order to analyze the influence of genotype and year of production on yield, thousand-kernel weight and hectoliter weight. The experiment was set up according to a randomized block system in three replications on the soil type. The main crop in the first year was sunflower, while in the second and third year it was corn. During the three-year research, the Agrosava Apilco and NS Igra varieties had the highest average yield, while the Zvezdana variety had the lowest average yield, but the highest thousand-kernel weight. The average grain yield differed by year (variety/year interaction). In the favorable second production year, all varieties had a significantly higher yield, thousand-kernel weight and hectoliter weight compared to the first and third year of production.
