Abstract

For the first time, a comparative karyotype analysis of closely related species Hedysarum gmelinii andH. setigerum (Hedysarum section Multicaulia) grown in Southern Siberia, has been performed by molecular cytogeneticmarkers. Chromosome numbers in karyotypes of these species were specified – 2n = 4х = 32. In some accessions, additionalB chromosomes were revealed. FISH analyses indicated high similarities in chromosome morphology and also patternsof chromosomal distributions of 45S and 5S rDNA clusters in karyotypes of H. gmelinii and H. setigerum, which confirmsthe close relationship between their genomes.
