[Influence of Vrn-B1a and Vrn-B1c alleles on length of developmental phases of substitution and near-isogenic lines of common wheat].

The influence of Vrn-B1a and Vrn-B1c alleles on the length of developmental phases in lines of winter cv. Sava with intervarietal substitution of chromosomes 5B and near-isogenic lines (NILs) with these loci in the genetic background of winter cv. Bezostaya 1 is studied.
