摘要: 采用ISSR 分子标记技术对48 个引种和选育的油橄榄品种进行遗传多样性和聚类分析。11 条筛选出的引物共扩增 出106 条DNA 谱带,其中有99 条为多态性条带,多态位点百分率为93.40%。数据表明所分析的油橄榄种质具有丰富的遗传多样性。 根据各品种的Nei’s 遗传距离,运用UPGMA 方法构建了所有品种的聚类图,结果48 个油橄榄品种被聚成了4 个大类;84.6% 的 国内选育品种聚于2 个类群中;多数引种品种并没有按照地理起源而是依据引种材料来源地和主要用途聚类。研究结果为油橄榄 种质资源的利用以及进一步的良种选育提供参考。

Abstract: Inter-simple sequence repeat(ISSR)molecular markers were applied to analyze genetic diversity and clustering of 48 introduced and breeding olive cultivars. 106 bands were amplified by 11 selected primers,among which 99 bands were polymorphic. Percentage of polymorphic loci was 93.40%,which showed a rich genetic diversity in the collection. Based on Nei’s genetic distances,dendrogram of 48 cultivars was constructed through unweighted pair-group method(UPMGA). 48 cultivars were clustered into 4 main groups. 84.6% of native select and breeding cultivars were clustered into 2 groups and most of introduced cultivars were clustered based on their directly introducing places and main usage. The results will provide references for olive resource utilization and further genetic improving.
