WHEAT YIELD STABILITY ACROSS YEARS WITH VARYING CLIMATE CONDITIONS

Abstract

This paper aimed to investigate the yield stability of 19 wheat winter varieties using the AMMI model. The experiment was carried out in the experimental field of the Center for Small Grains and Rural Development in Kragujevac during a three-year period (2019/2020, 2020/2021, 2021/2022). The Perfekta, and Javorka varieties stood out as the most stable varieties for grain yield. At the same time, the Perfecta variety achieved the highest grain yield at the level of the entire experiment indicating that this variety maintains its superiority even in less favorable climatic conditions, on soils of poorer fertility. This significantly contributes to safe and sustainable agricultural production.
