    摘要:

    采用InDel、ESTSSR和SSR组合分子标记技术研究94份引种至昆明地区的荷花种质的遗传多样性,结果显示:筛选出的60对引物共扩增出204条条带,检测到等位基因233个。3种标记平均Shannon 指数≥0.85,基因多样性指数≥0.52,多样性检出率较高。通过Mantel检测表明组合标记与各个独立标记的相关性r值均高于0.789 4。采用组合标记进行聚类分析和群体结构分析均将94份种质资源划分为5个类群,与传统分类及种源地分类存在一定关联。美洲莲与亚洲莲的遗传多样性存在明显差异,遗传组分分析结果表明不同品种的中美杂交莲也存在差异,分布于美洲莲或亚洲莲中。综上,引种至昆明地区的94份荷花资源遗传多样性丰富,组合标记在荷花种质资源的多样性检出率较高,可为后续优良品种选育提供种质资源和技术支撑。

    Abstract:

    The combined molecular markers including InDel,ESTSSR and SSR were used to analyse the genetic diversity of 94 lotus germplasms introduced in Kunming region. The results showed that a total of 204 bands were amplified by the 60 pairs of primers screened,and 233 alleles were detected. The average Shannon’s index of the three markers was more than 0.8,the index of gene diversity was above 0.52,indicating that the detection rate of diversity is high.The result of Mantel test showed that the correlation r values between the combined markers and each independent marker were all higher than 0.789 4. Ninetyfour germplasms were divided into 5 groups with cluster analysis and population structure analysis of combined markers,which was related to traditional classification and provenance classification. There were obvious differences in genetic diversity between American lotus and Asian lotus. According to genetic composition,SinoAmerican hybrid lotus is distributed in American lotus or Asian lotus. In summary,the 94 lotus resources introduced to Kunming are rich in genetic diversity,and the combined molecular markers have a high detection rate of diversity in lotus germplasm resources. It will provide germplasm resources and technical support for further selecting and breeding elite lotus varieties.
