采用Griffing方法4 模型Ⅰ,对7个自交系10个性状进行配合力的研究。其结果表明, 一般配合力的效应值及特殊配合力的效应值在同一亲本的性状之间或同一性状在不同亲本之间都有很大的差异。4113、7922、云143、云146在多数性状中一般配合力效应值高。就单株粒重而言, 4113、云143、云146具有较高的特殊配合力效应值, 4113在单株粒重方面具有较小的特殊配合力方差, 表明它能将高产性能稳定地遗传给子代 Griffing method 4 model Ⅰ was used to study the combining ability of 10 traits in 7 inbred lines. The results showed that the effect value of general combining ability and the effect value of special combining ability differed greatly among the parents of the same parental trait or the same trait. 4113, 7922, Yun 143 and Yun 146 have the highest GCA value in most traits. In terms of grain weight per unit weight, 4113, Yun 143, and Yun 146 had higher special combining ability effects, and 4113 had a smaller variance of specific combining ability per grain weight, indicating that it can stably inherit high yield performance Give children
