以对大豆灰斑病（ＣｅｒｃｏｓｐｏｒａｓｏｊｉｎａＨａｒａ）抗感不同的５个亲本配制的５个杂交组合，对其Ｐ１，Ｐ２，Ｆ１，Ｆ２，Ｆ３，Ｂ１，Ｂ２各群体用８个灰斑病生理小种的孢子菌丝悬浮液混合接种，进行了田间抗性表现的遗传分析。根据其分离和均值表现指出其数量遗传特征，并分析比较了病斑型、病斑数、病斑面积百分率和病斑型级数的世代相关和遗传力，指出其在抗病育种中的应用。 Five cross combinations of five parents with different resistance to Cercospora sojinaHara were used in this study. Eight individuals of P1, P2, F1, F2, F3, B1 and B2 Spore mycelium suspension inoculation, conducted a field analysis of genetic resistance. Based on their segregation and mean performance, the genetic characteristics of their numbers were pointed out, and the generational correlation and heritability of lesion type, lesion number, lesion area percentage and lesion type series were analyzed and compared, and its application in disease resistance breeding was pointed out .
