Genetic diversity in collection of cultivars and varieties of Triticum durum Desf. from Azerbaijan

Abstract

AFLP analysis of 144 samples of tetraploid wheat species, including cultivars and landraces of Triticum durum from Azerbaijan, was conducted. We obtained 249 fragments, 189 (76%) of which were polymorphic. The Dice genetic similarity index ranged from 0.67 to 0.99. Principal coordinate analysis revealed clear differences between the group of wheat with A^uA^uBB genome and the group of wheat with A^bA^bGG genome. Within the group of wheat with A^uA^uBB genome, differentiation was less pronounced, and this group was not divided into separate subclusters. It was shown that the Azerbaijani varieties of durum wheat were fairly similar to each other and with other species of Triticum durum.
