| 摘 要： | 用３个普通玉米自交系和６个０２玉米自交系进行双列杂交，分析了参试自交系的单株产量、３００粒重、容重和收获时籽粒含水量４个性状的一般配合力（ＧＳＡ），并对这４个性状的遗传力进行了估算。配合力分析表明，同一亲本的不同性状ＧＳＡ有很大差异，同一籽粒性状在不同亲本间ＧＳＡ也有很大差异。根据自交系各性状ＧＳＡ和ＧＳＡ方差，筛选出３个优良亲本，并获得５个较好组合。籽粒容重和收获时籽粒含水量在遗传上主要受加性基

| Abstract: | T ree normal and six opa ue-2 (02) inbred lines of maize were tested in adialed design including thirty-six crosses. The estimates of combining ability andgenetic parameters on ear kernel weight. 300-kernel weight. kernel density andmoisture content of kernel in harvesting were analyzed. The analysis of combiningability showed that there existed a large differences among the general combiningability of parents for one kernel characters, and the case was true among the GCAof kernel characters for one parent. three good parent inbred lines were selectedby combing ability analysis, five better crosses were also selected. additive genieeffect was more important than non-additive for kernel density and moisturecontent, but both were important for kernel and ear kernel weight. |
