摘要: ISSR技术分析了38个杧果(Mangifera indica L. ) 品种的亲缘关系。从60条ISSR引物中
筛选出10条重复性好、扩增带型清晰的引物, 共扩增出79条可重复性带, 多态性带比例为86.7%。扩增
结果可区分38个品种中的37个(含红金龙或贵妃之一) 。各品种间遗传距离在0~0.682之间, 平均为
0.393。UPGMA聚类将供试品种分成了5类。对分类结果进行了讨论。

关键词: 杧果, 亲缘关系, ISSR, 聚类分析

Abstract: The genetic relationship s of 38 mango (Mangifera indica L. ) accessions were examined by
ISSR markers. Of the 60 ISSR p rimers screened, only 10 p rimers gave rep roducible, polymorphic DNA ampli
fication patternswith a total 79 of amplified bands. Their percentage of polymorphic band was 86.7%. By
banding patterns obtained from these 10 primers, each accession could be distinguished from the others excep t
either Hongjinlong or Guifei, since the two accessions had the same amplified band patterns. Genetic distances
among the tested accessions ranged from 0 to 0.682 with an average of 0.393. Five group s were formed by
UPGMA clustering and the classification results were discussed in this paper.

Key words: Mango, Mangifera indica L., Genetic relationship, ISSR, Clustering analysis
