Abstract

Duration of vernalization requirement in various winter wheat cultivars and its inheritance in F1 and F2 have been studied after crossing of contrast genotypes. Partial dominance of shorter requirement has been revealed in F1 hybrids. Segregations in F2 populations have shown the action of two non-allelic genes of different expression. Revealed genes are proposed to designate as Vrd according to the first letters of term “vernalization requirement duration”. In conformity with this symbol the haploid genotypes of investigated cultivars are: Vrd1 vrd2 — Norin 1 and Olvia; vrd1 Vrd2 — Chayka; vrd1 vrd2 — Mironovskaya 808 and Eritrospermum 604.
