取国内主栽秋蚕豆和国外主产区蚕豆品种各6份进行农艺、品质性状的遗传多样性研究。结果表明，在考察的9个主要农艺及品质性状中，总粒数的变异系数最大，为79．66％，生育期的变异系数最小，为3．58％；在相关性方面，蛋白质含量与百粒重，总粒数与总荚数、分枝数，总荚数与分枝数达到极显著正相关，而支链淀粉与蛋白质含量达到极显著负相关；采用 Ward 法进行聚类分析，结果表明当平均欧式距离 D2为5时可将12份品种分为三大类群：第Ⅰ类群5个品种，第Ⅱ类群2个品种，第Ⅲ类5个品种。地理距离近的品种并没有聚在一起，说明品种的亲缘关系与地理来源关系不大，也说明12份来自国内外蚕豆品种具有明显遗传多样性。

Twelve faba bean varieties,6 domestic autumn-sowing and 6 introduced from foreign countries,were studied in genetic diversity for their agronomic and quality traits. The results showed that,among 9 traits,the coefficient of variance in total bean number and growth period was the largest one and the smallest one for 79.66%and 3.58%,respectively. The correlation coefficient was significantly positive between protein content and hundred bean weight,the total bean number with total pod number or branch number,the total pod number with branch number,but was significantly negative between amylopectin content and protein content. The 12 varieties were clustered into 3 groups by mean of Euclidean distance in D2 as 5,and the quantity of varieties inⅠ,Ⅱand Ⅲ groups was 5,2 and 5 varieties,respectively. The varieties in geographic distance close did not gather together. It meant that the geographic origin of the varieties might not be relative to their genetic relationship.
