【摘要】 利用 AFLP 技术对30个甜瓜材料进行多态性和聚类分析研究。从120对 MseI 和 PstI 引物中筛选出25对扩增效果好的引物,共扩增出262条多态性带。聚类分析结果新疆甜瓜中的夏甜瓜类型,新疆甜瓜中的冬甜瓜类型、美国粗皮甜瓜类型、日本甜瓜类型、梨瓜类型各聚为一组。上述材料的聚类分析结果与依据生态类型和地理起源的分类结果基本吻合,表明 AFLP 用于甜瓜种内不同材料间的遗传变异性分析是可行的。更多还原

【Abstract】 AFLP markers were applied to 30 melon accessions to study polymorphism and cluster analysis.Twenty-five primer combinations were used to generate 262 polymorphic bands.The cluster analysis showed that the accessions within the same mutation or the same origin were assembled in the same group.The result of cluster analysis was basically consistent with the classification according to the ecotype and geographycal origin,which indicates that AFLP markers are useful for genetic analysis of melon accessions.更多还原
