XVI International Botanical Congess

A total of 414 accessions of Triticum aestivum L. (345), T. compactum Host (34), T. spelta L. (26), T. sphaerococcum Perc. (3), T. macha Dek. et Men. (2), T. vavilovii Jakubz. (2) and T. petropavlovskyi Udacz. et Migusch. (1) were selected from the VIR germplasm collection. The 28 random primers yielded 137 scorable polymorphic bands. The results of principal coordinate and cluster analyses of these data have demonstrated that all studied accessions organize the united genepool, which is differentiated into 4 principal groups of accessions originated largely from India and Pakistan (1), China and Japan (2), European (3) and Irano-Turkestanean (4) regions. Such a division is in accordance with ecogeographical classification proposed by N.Vavilov (1964).
