应用SSR标记分析中国北方名优绿豆的遗传多样性

利用39对SSR分子标记对78份中国北方名优绿豆品种进行遗传多样性分析,共检测出104个等位变异,平均为2.74个。不同引物所揭示的试验材料多态信息含量(PIC)变幅在0.03~0.58之间,平均0.26。分析4个地理来源的名优绿豆资源,结果表明内蒙古的等位变异数和多态信息含量值最大,是传统名优绿豆种质资源最丰富的地区,河北张家口次之。聚类分析表明河北张家口和山西大同的种质为组群Ⅰ,内蒙古和吉林白城的资源为组群Ⅱ。

Genetic Diversity of Traditional Famous Mungbean Landraces in China by SSR Markers

In this study, genetic diversity of 78 traditional mungbean varieties of North china were analyzed by 39 SSR molecular markers, total 104 allelic variations were detected with an average of 2.74. The polymorphic information content (PIC) of ed materials detected by different primers varied from 0.03 to 0.58 with an average of 0.26. The analysis of mungbean resources from 4 geographic origin indicated that Inner Mongolia was the most diversity region of traditional mungbean resources ,with the highest allelic variation and PIC value, and the second was Zhangjiakou of Hebei province. Cluster analysis showed that germplasm from Zhangjiakou of Hebei province and Datong of Shanxi province were the first group, and those from Inner Mongolia and Baicheng of Jilin province were the second group.
