| 摘 要： | 利用RAPD标记对14份耐盐茄子种质资源进行遗传多样性分析。结果表明：从100个引物中筛选出10个多态性较好的引物，共扩增出102条带，多态性条带所占的比例为77.45%。聚类分析结果显示：14份耐盐茄子材料的遗传相似系数在0.316～0.975之间|在遗传相似系数0.47处可将14份耐盐茄子材料分为3大类，大部分种质资源（85.71%）都聚在第3类（栽培种），表明收集到的茄子耐盐种质亲缘关系较近。

| Abstract: | Genetic diversity in salt tolerant eggplant(Solanum melongena L.)cultivars was analyzed with RAPD technology.The results showed that 10 primers were screened from 100 RAPD primers and 102 polymorphic bands were amplified,the polymorphic band percentage was 77.45%.Clustering analysis showed that the value of genetic variation indexes of 14 eggplant cultivars based on the RAPD data were varied from 0.316 to 0.975.They could be classified into 3 groups at coefficient of 0.47 with UPGMA method,and most of the samples(85.71%)were gathered in the 3rd group(cultivated cultivars),indicating the collected germplasm with closer blood relationship. |
