摘要

Wide hybridization in wheat breeding helps to create cultivars with useful traits. Scientists of the Tsitsin Main Botanical Garden have been working on hybridization of wheat and its wild relatives. In recent years, by crossing × Trititrigia cziczinii Tsvel with Elymus farctus (Viv.) Runemark ex Melderis, promising hybrids with several useful traits have been obtained. The aim of this research was a complex study of the biological characteristics of one of the new hybrids (genotype ‘1/3’) in order to determine its prospects for use in wheat breeding. The studied genotype was determined to be octoploid and showed high crossing success, with 100% germination in hybridization with spring and winter wheat cultivars. The electrophoretic analysis of ‘1/3’ grain showed the presence of two biotypes and identified gliadin allelic variants, which determined the good baking properties. ‘1/3’ and its hybrids inherited micromorphological elements of the leaf surface specific to E. farctus, which can be used as markers in the breeding process. Therefore, this extensive research demonstrated the usefulness of using the genotype ‘1/3’ in future wheat breeding programs.
