Abstract


1499 spring barley accessions of various eco-geographical origin are evaluated in three-year cycles of study. To assess the impact of weather conditions on yield formation, regression coefficients were calculated of yield conditions to year conditions (bi). The accessions were shown with high and stable yield level (bi = 0,50 - 0,99), as well as with medium (bi = 1,02 - 1,16) and intensive response to changing climatic conditions (bi = 1,17 - 1.99).
