Microevolutionary relationships between biotypes of Elymus confusus, E. peschkovae, and E. sibiricus (Poaceae) according to hybridization and sequencing of the nuclear gene GBSS1 (waxy)

According to descriptions, the Siberian species E. peschkovae and E. confusus differ in the presence or absence of trichomes on lemma and rachilla surfaces only. Two methods were used for study microevolutionary relationships between these species: hybridization of biotypes from different locations...
