摘要 以19份酸豆资源为试材,采用SRAP标记技术,研究了酸豆遗传多样性,以期为酸豆资源的育种利用提供参考依据。结果表明:126对引物组合中有15对引物扩增条带清晰,多态性条带百分率大于25%,扩增出135条清晰的条带,其中72条为多态性条带,平均每对引物组合扩增出9条带,其中4.8条多态性条带,平均条带多态性百分率为53.12%,19份酸豆资源的遗传相似性系数在0.602~0.947,平均为0.791,UPGMA聚类分析,可将19份酸豆资源聚类四大类,野生材料之间的遗传差异小;非野生材料之间的遗传差异大于野生种。 In order to provide the foundation for the breeding,genetic diversity among 19 genetic resources of tamarind(Tamarindus indica L.)from Yunnan and Hainan was analyzed by using sequence-related amplified polymorphism(SRAP)markers.The results showed that 15 of 126 SRAP pairs of primers could amplify the clear and high polymorphism bands,polymorphic band percentage>25%.Using these 15 pairs of primers amplified 19 tamarinds by SRAP,a total of 135 amplified clear bands were obtained,of which 72 were polymorphic bands,per primer combination could amplify 9 bands,in which 4.8 polymorphic bands,the average percentage of polymorphic bands was 53.12%,the genetic similarity coefficient was 0.602-0.947,averaging 0.791;19 Tamarindus resources were divided into four classes by the results of UPGMA clustering.Genetic differences between wild materials were small,genetic differences between non-wild materials were greater than that of wild species.
