title: [Uniformity of distributing alleleic variants of three hordein-coding loci of spring barley in the Russian Federation].
abstract: The distribution of alleles of the hordein-coding loci Hrd A, Hrd B, and Hrd F was investigated in 101 spring barley cutivars grown in 12 regions of Russia in 1999. It was demonstrated that the genetic structure of populations of these cutivars in the regions studied was affected by climatic factors, such as the average June temperature and average annual precipitation. The distribution patterns of the Hrd alleles 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.
