The effects of gene Rht8 alleles at agronomic traits of winter bread wheat in the conditions of South Steppe of the Ukraine

Resistance to frost, winterhardiness, yield and its components were investigated in recombinant-inbred lines F₅ Odesskaya 16/Bezostaya 1 and 61 winter wheat varieties differing on the alleles of Rht8 gene. The absence of influence of gene Rht8 different alleles on the tested traits was shown. The high frequency of distribution of alleles Rht8c in modern wheat varieties developed in Plant Breeding and Genetics Institute is a result of high frequency of use of this allele in genetic pool after 1959.
