【摘要】 从36对SSR引物中筛选出10对引物,能在24个珍珠豆型花生品种DNA中扩增出多态性片段,每对SSR引物可扩增出1～6个DNA片段,扩增位点数为2～11个,平均6.5个;多态性位点为1～11个,平均6.1个。根据SSR标记分析24个珍珠豆型花生的遗传距离为0.04～0.69,平均为0.37。聚类分析将24个珍珠豆型花生品种划分为4个品种群。更多还原

【Abstract】 Simple sequence repeats (SSR) analysis with ten of thirty six SSR primer pairs isolated from groundnut DNA showed distinct polymorphism among 24 genotypes of var. vulgaris Harz in A.hypogaea L. 1～6 DNA fragments were amplified by PCR with each primer pairs and 2～11 loci were amplified, with an average of (6.5.) Average polymorphic loci were 6.1 and ranged from 1 to 11. Average genetic distance between the tested genotypes was 0.37 and ranged from 0.04 to 0.69. The 24 genotypes could be divided into four cultivar groups based on the clustering result.更多还原
