【摘要】 利用ＲＡＰＤ分子标记技术，对５６个绿豆组品种（系）进行亲缘关系研究。在选用的４５个随机引物中，均发现有不同的扩增产物。通过聚类分析将它们分成黑吉豆、野生绿豆和栽培绿豆３个种群。在栽培绿豆中又可分出印度抗豆象、巴基斯坦抗黄花叶病毒、中国Ⅰ组、中国Ⅱ组和亚蔬绿豆５个类型组。获得绿豆组３个豆种及其代表品种的独特标记，为今后食用豆种质资源鉴定与分类和遗传分析提供理论依据。更多还原

【Abstract】 RAPD markers were used to study relationships among species in mungbean group. Fifty six accessions, including 52 mungbean ( Vigna radiata ), 2 black gram (V. mungo )and 2 wild types ( V. sublobata) were examined with 45 random 10-mer primers which produced different RAPD bands among them. These mungbean accessions can be classified into 3 species, i. e. , the black gram species, wild mungbean species and cultivated mungbean species. In addition, the last species can be further divided into 5 groups, namely, the Indian resistant bruchid group, the Pakistani resistant yellow mosaic virus group, Chinese I group, Chinese I group and AVRDC group. The peculiar markers of 3 species and advanced varieties were generated and provided a theoretical background for the evaluation, taxonomy and genetic identity of food legumes germplasm resources.更多还原
