Abstract

The genetic relationship among 35 beer barley varieties,including 10 Gansu and 25 foreign varieties were investigated by SSR.The results showed that among the 49 pairs of SSR primers used,32 pairs of SSR primers detected polymorphisms.Clustering analysis showed that the range of between genetic similarity coefficient(GS) located in between 0.0500~0.6667.At the level of 0.26 GS,these varieties could be clustered into 4 groups,the majority of Ganpi series varieties(lines) were located in the same group,indicated that the genetic basis was rather narrow.The imported varieties had relatively wide range,indicated that their genetic basis is more extensive.
