ALLOPOLYPLOIDY AND ORIGIN OF GENOMES IN THE ELYMUS L. SPECIES (A REVIEW)

Abstract

All Elymus L. species are allopolyploids, whereas primary diploids are not part of this genus (with 2n = 14, x = 7). Widespread in Russia are mainly the species with genomic formulae StH, StY and StHY. According to the nomenclature system of Triticeae genomes, in the Russian Federation there are 53 species of Elymus with genomic constitutions StH, StY (2n = 4x = 28) and StHY (2n = 6x = 42). Key words: Elymus, molecular phylogeny, hybridization.
