摘要
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。
RAPD markers were used to study genetic diversity of 12 arrowroot varieties, which have separate sources in Chongqing area. The main results were summarized as follows： the genetic distances between varieties were with an average of 0.19, ranged from 0.00-0.36, 12 varieties were both classified into 3 groups according to genetic identity and puerarin L. content.
