水稻半矮生品种对改良株型 ,提高干物质生产能力有良好的效果 ,同时表现高度的抗倒伏性 ,因而对世界各稻作地区的增产起着极为主要的作用。我们发现水稻半矮生性基因 sd- l与不同的微效基因共同作用 ,可以使水稻株高这一性状有不同的表现。因而适当的株高成为理想株形和超高产
Semi-dwarf rice varieties have a good effect on improving plant type and improving dry matter production capacity, while exhibiting a high degree of lodging resistance, thus playing a very important role in increasing yield in various rice-growing areas of the world. We found that rice semi-dwarfing gene sd-l and different micro-genes together, can make the plant height of rice have different performance. Therefore, the appropriate plant height to become the ideal plant and super high yield
