Abstract
Ten winter rye varieties of Russian breeding were evaluated by yield in the conditions of Kirov region. The average yield of winter rye varieties during the research period of 2015-2021 was 2.64 t/ha and varied by years from 1.39 t/ha (2016, index of environmental conditions (Ij) = -1.25) to 4.22 t/ha (2015, Ij = 1.58). The variation of average yield by varieties was from 1.64 (Saratovskaya 7) to 3.62 t/ha (Flora). The proportion of the influence on the yield of the factor "conditions of the year" was 43 %, of the factor "variety" − 28 %. Different adaptability and environmental sustainability of winter rye varieties are indicated by: coefficients of plasticity (bi) – 0.40...1.39, stability (σd2) – 0.25...1.07, multiplicity (KM) – 1.31...2.97, adaptability (CA) – 56.3...142.4, variation (V) − 25...87 %; phenotypic stability factor (SF) − 1.9...20.5; yield spread (d) − 0.47...0.95, home-ostability (Hom) − 0.02...0.13 and stress tolerance (Y2 - Y1) – -2.28...-3.62. Based on the summation of the ranks according to 9 indicators of adaptability and environmental stability of the «yield» trait, the varieties most adapted to the limiting environmental factors (Falenskaya 4, Alice, Rushnik and Flora) have been chosen.
