摘要
利用前期筛选出的18对SSR引物对96份不同来源的藜麦种质材料进行遗传多样性分析,构建DNA指纹数据库。结果表明,筛选的18对SSR引物共检测到94个等位基因位点,每对引物检测出3~10个等位基因基因位点;利用18对引物组合可将96份藜麦种质材料鉴定出来;96份藜麦遗传相似系数变幅为0.55~0.98,平均遗传相似系数为0.77;聚类结果将96份藜麦材料分为三大类。
The total of 18 pairs of SSR primers were selected to analyze the genetic diversity of 96 quinoa germplasm materials from different sources,and a DNA fingerprint database was constructed.The results showed that 94 alleles were detected by 18 pairs of SSR primers,and 3-10 alleles were detected each pair of SSR primers.Using 18 pairs of primers,96 quinoa germplasm materials could be identified.The genetic similarity coefficients varied from 0.55 to 0.98,with an average of 0.77.The 96 quinoa materials were classified into three categories.
