The distribution of alleles of the hordein-coding loci Hrd A, Hrd B, and Hrd Fwas investigated in 101 spring barley cultivars grown in 12 regions of Russia in 1999. It was demonstrated that the genetic structure of populations of these cultivars in the regions studied was affected by climatic factors, such as the average June temperature and average annual rainfall. The distribution patterns of the Hrdalleles in 25 agricultural provinces of the former Soviet Union and 12 regions of Russia were compared. The factor structure of genetic variability in the regions of barley cultivation in the former Soviet Union was found to differ from that in Russia. The change of the factor structure is likely to be related to diminishing the barley-production area under study and to the new administrative subdivision. [ABSTRACT FROM AUTHOR] |
