Abstract
Polymorphism and specificity in StY-genome species Elymus gmelinii (Ledeb.) Tzvelev and E. pendulinus (Nevski) Tzvelev widespread in the Asian part of Russia have been studied on the basis of the combined approach. Possibility of introgression between these species was considered with use morphological and ecological-geographical criteria, and also biochemical (SDS-electrophoresis of endosperm proteins) and molecular (ISSR-PCR) markers. The conclusion has been drawn that species E. pendulinus and E. gmelinii are rather isolated, and introgression signs at joint growth of species was not revealed.
