为摸清葛根遗传多样性的分布和种质间的遗传关系,促进葛根种质的有效利用,对12份重庆地区不同来源的葛根种质资源的遗传多样性进行RAPD分析和葛根素含量聚类分析。结果表明:RAPD分析葛根种质资源的遗传距离在0.00～0.36之间,平均为0.19;葛根种质资源遗传相似系数按类平均法,可聚为3类。按照葛根素含量聚类分析可以分为3类。
In order to find out the distribution of genetic diversity and the genetic relationship among germplasm resources and promote the effective utilization of pueraria germplasm, the genetic diversity of pueraria germplasm resources from 12 different sources in Chongqing were analyzed by RAPD and puerarin analysis. The results showed that the genetic distance between R gene and Germplasm resources was between 0.00 and 0.36 with an average of 0.19. The genetic similarity coefficient of Germplasm resources of Germplasm with Germplasm resources could be grouped into three groups according to the means of averaging. According to the puerarin content cluster analysis can be divided into three categories.
