摘　　要：[Objective]The aim was to analyze genetic diversity of SSR markers in Hordeum vulgare L.in Qinghai Province and lay a foundation for screening and protecting some excellent H.vulgare cultivars.[Method]SSR markers were used to evaluate the genetic diversity of 42 cultivated H.vulgare from Qinghai Province.[Result]42 H.vulgare showed polymorphism in 7 SSR markers locus.A total of 24 alleles were identified,and the number of alleles per locus ranged from 1 to 6,with an average of 3.0.According to SSR markers polymorphism,42 H.vulgare could be divided into 4 groups,namely I,II,III and IV.[Result]The study indicated that cultivated H.vulgare from Qinghai Province is rich in genetic diversity,which will provide reference for selecting parent of H.vulgare breeding.[目的]分析我国青海省青稞SSR标记遗传多样性,为具有某些优异特性的青稞品种或资源筛选及青稞资源的保护奠定基础。[方法]利用SSR标记评估42份青海省栽培青稞的遗传多样性。[结果]42份青稞材料在7个SSR标记位点处表现出多态性,各位点扩增的等位基因数为1～6个,共鉴定出24个等位基因,每位点平均3.0个;根据SSR标记多态性可将42份青稞材料分为4组,即Ⅰ、Ⅱ、Ⅲ和Ⅳ。[结论]该研究表明青海省栽培青稞具有丰富的遗传多样性,可为青稞育种亲本选择提供参考。
