Analysis of the genetic diversity of Russian common oat varieties using alleles of avenin-coding loci

Alleles of avenin-coding loci were identified in 24 varieties common oat origin from 6 different breeding centers the Russian Federation. It was found that 33% studied are homogeneous. Heterogeneous contain 2 to 10 biotypes. The analysis revealed 67 genotypes, ten which spectra several at once. Despite presence matching all differ genetic formulas avenin, number and frequency occurrence This makes it possible effectively identify distinguish sown by using method prolamin electrophoresis. analyzed groups characterized high values (0.54-0.79) intra-population diversity, indicates stability populations. exception is originating Irkutsk region, low diversity population may indicate process erosion. Analysis distribution alleles does not allow determine whether belong certain centers, associated with introduction same genotypes into programs regions.
