The experiment was conducted in the experimental field of IRGR - Sadovo in the period 2018-2020. The sixteen old varieties of common winter wheat, created in IRGR, were tested in yield for two years. The yield, plant height and physical properties of the grain were obtained: 1000 g kernel weight and test weight (kg/hl). The obtained data are processed by statistical methods - dispersion, variation and analysis of the main components. The results show that the influence of the genotype, environment and their interaction has been proven in all monitored traits. All varieties have significantly higher yields than the standard. The highest grain yield was reported for the varieties Joanna, KM 135, Diamand and Guinness. There is no significant higher 1000 kernel weight and the test weight of only two varieties is significantly higher than the standard. The aim of the study is to test the effect of climate change on the grain yield, plant height and physical properties of old varieties of common winter wheat, as the main food crop, and to assess their resilience to climate change.
