摘　　要：为探讨云南猕猴桃属种质资源的亲缘关系,采用SSR分子标记方法对70份云南野生猕猴桃种质资源的亲缘关系进行分析。UPGMA聚类分析结果表明,70份猕猴桃种质资源在遗传相似系数0.17水平上可分为4个类群,类群Ⅰ共6份材料,包括滇东南麻栗坡的中越猕猴桃MLP001和MLP010、西畴的中越猕猴桃TSH-1和TSH-4,以及滇南屏边的中越猕猴桃PB001和PB005;类群Ⅱ共31份材料,主要包括滇东北的18份材料,滇西北的3份紫果猕猴桃TC-8、TC-1、TC-10,以及5份贡山猕猴桃CJ-11、CJ-13、CJ-7、CJ-3、CJ-2;类群Ⅲ共14份材料,主要包括滇东北的10份美味猕猴桃和中华猕猴桃系列材料,滇东的JZS-5、JZS-9及JZS-7,以及滇东南西畴的黄毛猕猴桃XPS-1;类群Ⅳ共19份材料,主要包括滇东北的16份材料,滇东南西畴的京梨猕猴桃XCFD-1及革叶猕猴桃XCFD-3,果实无被毛且果皮带斑点,果实较小,与其他类群具有较远的亲缘关系。SSR分子标记反映了云南猕猴桃属70份种质资源间的遗传亲缘关系,其中一些材料按种类、资源分布地及形态学性状特征形成明显有规律的聚类关系。In order to explore the genetic relationship of Actinidia germplasm resources in Yunnan,the genetic relationship of 70 wild Actinidia germplasm resources in Yunnan was analyzed by SSR molecular marker method.The results of UPGMA cluster analysis showed that the 70 Actinidia germplasm resources could be divided into four groups at the genetic similarity coefficient level of 0.17.Group I consisted of 6 materials,including A.indochinensis MLP001 and MLP010 from Malipo in southeastern Yunnan,A.indochinensis TSH-1 and TSH-4 from Xichou in southeastern Yunnan,A.indochinensis PB001 and PB005 from Pingbian in southern Yunnan.Group II consisted of 31 materials,including 18 materials from northeastern Yunnan,3 A.arguta var.purpurea TC-8,TC-1 and TC-10 from northwestern Yunnan,and 5 A.pilosula CJ-11,CJ-13,CJ-7,CJ-3 and CJ-2 from Gongshan.Group III consisted of 14 materials,10 A.deliciosa and A.chinensis series from northeastern Yunnan,JZS-5,JZS-9 and JZS-7 from eastern Yunnan,and A.fulvicoma XPS-1 from Xichou in southeastern Yunnan.Group IV consisted of 19 materials,16 from northeastern Yunnan,A.callosa var.henryi XCFD-1 from from Xichou in southeastern Yunnan,and A.rubricaulis var.coriacea XCFD-3 from Xichou in southeastern Yunnan.These fruits are hairless and smaller,and have a mottled skin.They have a distant relationship with other groups.The SSR molecular markers reflected the genetic relationship among the 70 germplasm resources of Actinidia in Yunnan,and some of them form obvious and regular clustering relationships according to species,resource distribution and morphological characteristics.
