| 摘 要： | 应用SSR分子标记对苜蓿新品系Dy-2006等6个苜蓿品种(品系)亲缘关系进行了分析.8对SSR引物共扩增出128个位点,106个位点显多态性,多态位点比率82.81%;不同苜蓿品种(品系)SSR多态性百分率存在一定差异,在32.81%～45.31%之间.遗传相似度(F)和遗传距离(D)的变化分别范围在0.9062～0.9689和0.0326～0.0762.聚类分析结果显示,新品系Dy-2006与龙牧801亲缘关系相对较近,与阿尔冈金亲缘关系较远,并与其它供试品种存在一定差异,为一个相对独立的品系.

| Abstract: | The genetic relationships among six alfalfa varieties including Dy-2006 were analyzed using simple sequence repeat markers.128 bands were amplified with 8 pairs of primers,among which 106 bands showed polymorphism,and the rate of polymorphic loci was 82.81%.There were differences in polymorphism percent among these varieties,ranging from 32.81% to 45.31%.The genetic similarity(F) ranged from 0.9062 to 0.9689 and genetic distance(D) ranged from 0.0326 to 0.0762.The results of cluster analysis indicated that ... |
