Studying the nature of inheritance of avenin components in F2 hybrids from crossing oat varieties of Siberian selection

Abstract. The purpose of this work is to study the nature inheritance avenin components and description new blocks in oat varieties cultivated Tyumen region for further use marker breeding. Methods. We analyzed grains F2 hybrids from crosses ?Tyumenskiy golozernyy × ?Megion, ?Otrada, ?Otrada ?Tyumenskiy golozernyy, ?Megion ?Otrada. Native electrophoresis was performed 13.2 % PAGE 4.0–4.5 h at a constant voltage 500 V. Results. In course research, it found that make up blocks. frequency distribution phenotypic classes each locus studied hybrid combinations corresponds assumption inherited as single codominant mendelian unit. synthesis controlled by three independent avenin-coding loci. Analysis individual made possible describe components, which Avn A – A9, A10, A11; one block B B7 C C8. On basis results obtained, complete protein formulas were drawn sowing oats: Tyumenskiy 2.7.3; Megion 2 + 9.7.5; Otrada 10 11.4.8. It spectrum only type standard insufficient leads errors identification component For more accurate identification, several should be used simultaneously obtain complex spectrum-standard combines locus. Scientific novelty. Described 5 components. These can assess intrapopulation genetic diversity varieties, well search adaptively significant economically valuable traits linked them.
