| 摘 要： | 对34份玉米自交系10个农艺性状遗传参数的分析表明，行粒数、穗重、穗粒重的遗传力和遗传进度较高，遗传变异范围广泛，直接选择的效果最佳。9种性状组合的间接选择对提高自交系穗粒重和穗重效果显著。

| Abstract: | The analysis of genetic parameters on ten agronomic characteristics of thirty-four maize inbred lines was conducted.The results showed that there existed the best effects on the direct seleetion to kemels per row,weight per ear,and kernel weight per ear because of those characteristics with higher heritabilities,genetic gains and a wide range of genetic variations.There appeared significant effects on indirect selection to both kemel weight per ear and weight per ear through nine kinds of characteristic combinations. |
