采用通径分析方法，研究了４８ 份菜豆品种资源３ 种主要病害（ 病毒病、炭疽病、枯萎病） 的抗病性与７ 个农艺性状的相关性。结果表明：荚长和荚宽对病毒病病情指数的直接作用最大；生育期对炭疽病病情指数的直接作用最大；荚长对枯萎病病情指数的直接作用最大。 The path analysis method was used to study the relationship between disease resistance and three agronomic traits of 48 major bean cultivars, including three major diseases (viral diseases, anthracnose and fusarium wilt). The results showed that the pod length and pod width had the most direct effect on the virus disease index; the direct effect on the anthracnose disease index during the growth period was the largest; the pod length had the greatest direct effect on the wilt disease index.
