摘要：

This study has shown that it is winter precipitation that has a greater effect on winter wheat grain yields and their stability. The effect of spring precipitation, for its part, depends more on the distribution than on the amount of precipitation. Significant differences were observed between the variety, years, and variety x year interactions in the study. During the twelve years of the trial, the highest-yielding winter wheat varieties were Somborka, Rodna, Milica, Novosadska rana 5 and Studena, while Milica and Ibarka turned out to have the greatest stability in addition to high yields. Somborka, Rodna and Novosadska mna 5 gave the highest yields in years with more spring precipitation (April to June period), while yeats with more precipitation in the winter turned our to be the most suitable for Danica and Studena.
