| 摘 要： | 为构建枇杷种质资源指纹图谱,采用SSR标记技术对国家枇杷种质资源圃33份品种进行多态性分析,从近缘属苹果属和梨属的51对SSR引物中筛选出能够稳定扩增,多态性好的7对引物,Hi01d05F、Hi12f04F、CH02B10F、Hi03a03、Hi03e04、Hi04a05和Hi02c07来构建指纹图谱。结果表明,应用这7对引物可100%区别33个枇杷种质。这种SSR标记构建的枇杷种质资源指纹图谱对于品种分类及鉴定具有重要的应用价值。

| Abstract: | SSR sequences are the reproducible, stable, rich polymorphism DNA molecular markers. Fingerprint patterns of the SSR markers for 33 loquat varieties in national loquat germplasm resource garden were constructed by specifically amplifying polymorphism from 7 pairs of primers screened from 51 pairs of primers of the relatives Malus and Pyrus. The results showed that, the uses of seven primers, Hi01d05F, Hi12f04F, CH02B10F, Hi03a03, Hi03e04, Hi04a05 and Hi02c07, could distinguish 33 loquat germplasm from one another, completely, providing an essential criterion for classification and identification of the loquat resources. |
