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 .95 39 Black waxy corn hybrids, the parent inbred lines ear longest cloverleaf leaves, the order of the lower leaves> ear leaves> upper leaves; leaf width order, upper leaves> ear leaves> lower leaves. There was no significant difference in the leaf area of ​​the three leaves, and there was a very significant positive correlation between the three leaves, which played a nearly equal important role.In the leaf area inheritance, the effect of the male inbred lines was larger than that of the female inbred lines, There was a significant and significant positive correlation between leaf area and yield per plant (r = 0.95 39)
