由于株型与光能利用密切相关,因而株型研究已成为当代作物育种上的重要课题。迄今为止,人们对水稻株型(除株高以外)遗传方面的知识还很欠缺,仅有零星资料表明,叶型和分蘖习性属于数量遗传及遗传参数。为此,笔者近三年开展了粳稻和籼稻株、叶型态的遗传研究,以期为水稻育种提供遗传参数。一、材料和方法 (一) 供试品种:大多为我国南方近 Because plant type and light energy utilization are closely related, plant type research has become an important issue in contemporary crop breeding. To date, there is a lack of knowledge about the genetic aspects of rice plant types (except plant height). Only sporadic data show that leaf type and tillering habits are quantitative and genetic. For this reason, in the past three years, I carried out genetic research on japonica and indica rice plants and leaf types, in order to provide genetic parameters for rice breeding. First, materials and methods (A) test varieties: mostly in southern China near
