| 摘 要： | 黑糯玉米杂交种、亲本自交系果穗三叶下位叶最长，其大小依次为，下位叶＞穗位叶＞上位叶；叶片宽度排序依次为，上位叶＞穗位叶＞下位叶。果穗三叶叶面积差异不大，且三叶间呈极显著正相关，起着几乎同等重要的作用。在叶面积遗传中，父本自交系的作用比母本自交系大一些，杂交种叶面积与杂交种单株产量呈极显著正相关，r=0.9539^**。

| Abstract: | The inferior leaf of hybrid and self line is the longest,the high to low sequence is inferior leaf,spike leaf,superior leaf.The big to low sequence of leaf wide is superior leaf,spike leaf,inferior leaf.The leaf area of three ear leaves have no significant difference,they have the same inportant effects.In the heredity of leaf area,male self line is more important than female self line,and it has significantly positine corelation between leaf area and single plant yield of hybrids. |
