摘　　要：对５０个蚕豆品种的７个数量性状进行了遗传主成份分析，初步提出了评选蚕豆品种的遗传主成份标准，并筛选出１８个综合性状优良的亲本品种。测定了５０个蚕豆品种的遗传距离，根据遗传距离大小，将５０个蚕豆品种聚类为２群、３类、９组。分类结果指出，蚕豆品种的遗传距离大小与地理差异有些似有一定关系，但在总体上，二者间无必然联系。Analysis of major Genetic component analysis was performed for 7 quantitative characters of 50 faba bean lines and, according to the analysis, 18 lines were selected as parents. The 50 lines were classified into 2 subpopulations, 3 types and 9 groups according to their genetic distance. The results showed that there was seemly a correlation between geogrophical distribution and genetic distance, nevertheless most lines within the same cluster were close in genetic distance but far in geogrophic sites.
