| Abstract: | RAPD markers were generated from 6 groups of Tibetan hulless barley (23 varieties): Lasagoumang, QB, Zangqing, Guoluo, Dongqing,
and Hymalayia. Of the 48 fragments generated by 5 selected primers (among 68 primers), 44 appeared to be polymorphic (92%).
Cluster analysis was performed (RAPDistance 1.04). The 23 varieties were divided into 2 groups, and the molecular foundation
of genetic diversity was explored. In addition, to identify the varieties, one DNA fingerprint was constructed based on 17
bands amplified with S32 and 2 bands with S18. A specific RAPD fragment can be used to select for high and low β-glucan content
varieties.

Plant Resource System of Southwest China”. |
