Última Genetic diversity and geographical differentiation of cultivated six-rowed naked barley landraces from the Qinghai-Tibet plateau of China detected by SSR analysis Genet. Mol. Biol. Feng,Zong-Yun; Zhang,Li-Li; Zhang,Yi-Zheng; Ling,Hong-Qing. Cultivated six-rowed naked barley (Hordeum vulgare ssp. hexastichon var. nudum Hsü) is the oldest cultivated barley in China. We used 35 simple sequence repeat (SSR) markers selected from seven barley linkage groups to study the genetic diversity, geographical differentiation and evolutionary relationships among 65 H. vulgare ssp. hexastichon landrace accessions collected from the Qinghai-Tibet plateau of China, 25 accessions from Tibet (TB), 20 from Qinghai (QH) and 20 from Ganzi (GZ) prefecture in Sichuan province. At the 35 SSR loci we identified 248 alleles among the 65 accessions, 119 (47.98%) of the alleles being common alleles. We also found that the TB accessions possessed 47 private alleles, about 1.5 times more than the 31 private alleles found...

Biol. Naeem,Rehan; Dahleen,Lynn; Mirza,Bushra. Genetic diversity in 403 morphologically distinct landraces of barley (Hordeum vulgare L. subsp. vulgare) originating from seven geographical zones of Asia was studied using simple sequence repeat (SSR) markers from regions of medium to high recombination in the barley genome. The seven polymorphic SSR markers representing each of the chromosomes chosen for the study revealed a high level of allelic diversity among the landraces. Genetic richness was highest in those from India, followed by Pakistan while it was lowest for Uzbekistan and Turkmenistan. Out of the 50 alleles detected, 15 were unique to a geographic region. Genetic diversity was highest for landraces from Pakistan (0.70 ± 0.06) and lowest for those from Uzbekistan (0.18 ± 0.17). Likewise,...
