在水稻育种工作中,株型已成为主要的育种目标之一。植株的高矮及其形态,对水稻的群体结构及产量,都有着明显的影响。特别是我国南方籼稻品种—矮脚南特的育成,开辟了水稻矮化育种的新途径,引起了国际上的广范重视。有些单位已开始了对水稻株型的研究工作。但除对株高这一性状的研究较为深入以外,而对其它性状的研究则较为淡薄,一般多流于文学上的简单叙述,而欠缺数理方面的具体指 Planting has become one of the major breeding objectives in rice breeding. The height and shape of the plants have a clear effect on the population structure and yield of rice. In particular, the breeding of south China indica variety Dwarf Nanant opened up a new way for dwarf breeding in rice, arousing widespread attention in the world. Some units have started research on rice plant type. However, except for the research on plant height and its traits, the research on other traits is relatively weak, and generally it is often narrated in literature. However,
