Siberian oat varieties' biochemical passports catalog

The purpose of the study is to compile biochemical passports of Siberian oat varieties using the prolamin electrophoresis method for copyright protection and use in the breeding process. The material for the study was the cultivars of oats bred at the Scientific Research Institute of Agriculture of the Northern Trans-Urals - a branch of the Tyumen Scientific Center of the Siberian Branch of the Russian Academy of Sciences. It has been established that varieties Megion and Otrada consist of two biotypes with a ratio of 2:1. The remaining varieties are homogeneous in terms of the component composition of avenin. Based on new data on the nature of the inheritance of avenins, genetic formulas of the studied varieties were compiled: Megion - AvnA2+9 B7 C5, Tyumensky golozerny - AvnA2 B7 C3, Talisman - AvnA11 B4 C2, Otrada - AvnA10 + 11 B4 C8, Foma - AvnA11 B11 C8, Tobolyak - AvnA4 B8 C2. Alleles A11, B4, B7 and C8 have the maximum frequency of occurrence in the studied varieties. These alleles are promising for further study and use as markers of highly competitive gene associations that are important in the climatic conditions of Western Siberia. As a result of clustering, it was found that in the region there are two groups of varieties of local selection, each of which is characterized by the presence of its own adaptive gene complex. The new variety Tobolyak was not included in any of the clusters, which may indicate that it has new combinations of genes that provide advantages at the present stage of breeding. The average genetic diversity is 0.82, which indicates the absence of genetic erosion processes and well-organized breeding work with the crop in the region.
