摘　　要：高大韧稻育种论是水稻育种上的一个新学说,也是今后的发展方向,主攻高产的目标。阐述了水稻由高秆到矮秆,现又由矮秆返高粗韧秆的有着本质不同的新飞跃。利用多年来实践获得的结果说明培育根发达、茎粗韧、秆适高、叶挺坚、穗长大、结实高、谷饱满是获得高产的关键,也是今后水稻育种的发展趋势。Higher, thicker and tougher rice breeding is a new theory of rice breeding, is the developing direction, and is the target for gaining high yield also. The paper elucidated that it was a new leap for rice breeding from high stem to short stem, then to higher, thicker and tougher stem. It is a new leap from high stem to short stem, then to higher, thicker and tougher stem during rice breeding development. According to our experiences of rice breeding for a long time, The rice plant-type have a lot of advantages including developed root system, thicker and tougher stem, proper plant height, solid and upright leaf, bigger fringe, higher fruiting rate, plumped grain, high resistance and yield. The advantages are the key of gaining high yield, and are the developing direction of rice breeding.
