| 摘 要： | 利用28对稳定的SSR引物分析了20份玉米地方品种的遗传多样性,共检测到124个等位基因,平均每个位点4.43个,每对引物可以稳定检测到2～9个多态性片断,遗传相似系数为0.56～0.85.聚类分析将此材料划分为3个大群,其中来自山西地方品种划分在一个类群内,而来自河南的地方种质分布在3个类群中,多样性较高.据此结果,可对这些地方品种进行针对性的保存和改良利用.

| Abstract: | Genetic diversity of 20 maize landraces was analyzed with 28 SSR markers.124 alleles in all were detected and the average number of alleles was 4.43.2-9 polymorphic fragments were amplified stably by each SSR marker.Genetic dissimilarity coefficients ranged from 0.56 to 0.85.These maize germplasms could be clustered into 3 groups.The 10 maize landraces from Shanxi Province were clustered into one group.However,the other 10 maize landraces from Henan province were detected in 3 groups,showing a high genetic ... |
