Abstract
Much attention is currently being paid to studying the genetic resources of agricultural plants. Most spring wheat varieties have low genetic diversity, which impacts their productivity and quality. In order to increase the genetic potential of newly developed varieties, it is necessary to use other wheat species. The long-term study of the biological characteristics and agronomic traits of the tetraploid species of Kartalinskaya wheat with the BBAUAU genome has shown that this variety can be included in breeding programs in the Tyumen region. Therefore, the purpose of the current study was to analyze the inheritance of gliadin components in hybrids of the tetraploid species Triticum carthlicum Nevski. (=Triticum persicum Vav.). The crossings were conducted in the field in 2006. The laboratory study of the hybrids using polyacrylamide gel electrophoresis (PAGE) were conducted in 2009, and then in 2023 and 2024. On the obtained electropherogram data there were compiled binary matrices. As a result of the current study and the application of cluster analysis in two hybrid populations from direct and back crossings of Kartalinskaya wheat varieties K-17581 and K-32484, there have been identified linkage groups based on morphological traits. There have been identified three clusters in both hybrid populations (K-17581 x K-32484; K-32484 x K-17581). Application of a two-way hierarchical agglomeration algorithm to 24 phenotypic classes has revealed polymorphism in marker traits that are presumably inherited codominantly. The resulting hybrids have been included in further breeding and are currently undergoing testing in a control nursery.
