利用平展型和紧凑型两类杂交种,进行人工改型,证明株型是影响产量的重要因素;紧凑型育种,是融合了配合力和群体光能利用两个方面的理论;由于紧凑型玉米群体光分布特性好于平展型品种,所以,承受的叶面积指数高,生产潜力大。
The two types of hybrids, flat and compact, were used for artificial modification to prove that the plant type is an important factor affecting the yield. Compact breeding is a combination of combining ability and population light energy utilization. As the compact corn Light distribution characteristics of the population is better than the flat type, therefore, bear the leaf area index high production potential.
