| 摘 要： | 利用19对SSR标记引物对汕油系列和粤油系列的15个主要品种进行了遗传多样性分析,结果表明:有6对标记引物扩增出多态性,在15个品种间共检测到18个多态性等位点,每对引物分别检测出2~4个等位点变异,平均为3.0个,6个标记的多态性信息含量(PIC)在0.124~0.622;品种间的遗传相似系数在0.167~0.833,大部分品种间的遗传相似系数大于0.5;以遗传相似系数0.535为界,15个品种聚为4类。

| Abstract: | The genetic diversity among 15 peanut cultivars of Shanyou and Yueyou was analyzed with 19 SSR markers.The result showed that 6 SSR loci were polymorphism.Total 18 alleles were detected in 15 cultivars and the detected alleles were 2～4 per SSR locus with an average of 3.0.The polymorphism information content(PIC) of 6 SSR markers varied from 0.124 to 0.622.The genetic similarities(GS) among 15 cultivars ranged from 0.167 to(0.833) and those were more than 0.5 among most cultivars.15 cultivars were classified into 4 groups at 0.535 of GS. |
