Abstract

The result of identification of 86 home- and abroad-produced winter bread cultivar and lines genotypes for vernalization requirement duration genes have been presented. The short requirement of majority samples has been determined by the presence of Vrd1 or Vrd2 genes or both of them together. The presence of new gene Vrd3 has been revieled in the genotype of eight samples. Significant differencies in sets of PBGI and IPP cultivars and distinguishing both of them from the total set have evidenced breeding value of specific genotypes under certain conditions of wheat growing.
