以64份贵州地方樱桃(Prunus pseudocerasus L.)种质资源及栽培品种黑珍珠为试材进行ISSR分析。结果表明:用从90条ISSR引物中筛选出的21条稳定性强、条带清晰及多态性丰富的引物进行PCR扩增,共获得228个标记,其中多态性标记为199个,多态性比例为87.28%;采用NTSYS2.01软件计算,相似系数为0.49~0.90,表明贵州地方樱桃资源的多样性丰富;UPGMA聚类分析显示,毕节、遵义及黔南等地资源具有丰富的多样性,尤其毕节地区拥有大量品质优良的资源,可作为品质育种的亲本。
Cherry Germplasm from Guizhou Province Analyzed by ISSR Markers
Sixty-four cherry(Prunus pseudocerasus L.)accessions from Guizhou Province,as well as the cultivar Black Pearl,were analyzed by ISSR markers.A total of 228 markers were scored from the 21 primers,which were screened out from 90 primers and demonstrated highly reproducible,clear and polymorphic bands.Among the obtained markers,199 were polymorphic,accounting for 87.28% of the total.Analyzed by NTSYS2.01,the genetic similarity coefficient among the accessions ranged from 0.49 to 0.90,reflecting the high genetic diversity of cherry germplasms in Guizhou Province.The UPGMA dendrogram demonstrated that the accessions from Bijie,Zunyi and Qiannan areas were genetically more diversified.In particular the accessions from Bijie exhibited the highest degree of diversity in fruit quality,which may be used as elite materials for further genetic improvement in this species.
