| 摘 要： | 选择玉米株型性状时应以ＧＣＡ为主，重点考虑亲本自身的性状特点。株高ＧＣＡ与穗位ＧＣＡ、叶面积ＧＣＡ，穗位ＧＣＡ与叶面积ＧＣＡ，叶长ＧＣＡ与叶面积ＧＣＡ〈叶面积ＧＣＡ与叶片数ＧＣＡ之间相关显著或极显著，相互间选择有促进作用。辽７６、辽８７、辽５０８８、沈１３７等自交系可根据育种目标加以利用。

| Abstract: | GCA is a major factor for plant type traits selection in maize breeding. It is important to consider the characteristics of parents. Significant correlations between GCAs of plant height and ear position, leaf area,ear position and leaf area, leaf length and leaf area, leaf area and leaf number are found. The selection for one trait can improve others. Maize inbred lines such as Liao76,Liao87,Liao5088,Shen137 are ideal in hybrid plant type breeding. WT5HZ] |
