Morphological variability of Brachypodium pinnatum (L.) Beauv. in Siberia

Morphological traits of perennial rhizome Brachypodium pinnatum are investigated on the territory of Siberia. The species is heterogeneous morphologically and karyologically. Five qualitative features were revealed, which showed the greatest variability. In addition, based on a multivariate analysis of qualitative and quantitative traits, a correlation was established between morphological features and longitude and latitude of location. As a result of the studies, we found that the samples belong to one karyological race
