Abstract

Intra- and inter-population variability was studied and the similarity of populations of two species of thegenus Achillea (A. millefolium and A. asiatica) growing in the communities of the southern part of the Krasnoyarskterritory and Khakassia was analyzed. The principal component analysis identified the following diagnostic features: theheight of the common inflorescence, the width of the rachis with the wing, the size of the leaves in the middle and theupper formations and the number of tubular flowers. However, a clear differentiation into species is observed only forpopulations characterized by minimum and maximum values of these characteristics. Yemelyan populations, consistingof large individuals and growing on the border of meadow and forest communities, belong to the species A. millefolium,and populations, growing on steppe meadows – to A. asiatica. With most of the studied populations of yarrow, there weredifficulties species identification, apparently associated with the presence of transitional forms of hybridogenic origin.According to the set of selected diagnostic features, these populations are included in one cluster with A. asiatica.
