一、引言本世纪二十年代及三十年代加藤茂苞、卢守耕等进行籼粳稻杂交是研究栽培稻的亲缘关系,是栽培稻分类性质的研究。五十年代初期以来,国内外进行的籼粳稻杂交是有意识的育种研究。本研究始于1951年,至今已整整坚持三十年了。回顾过去,展望将来,我们深感理想株形的研究是今后水稻高产育种理论方面的重要研究,因为株形育种是实际可行的高光效育种,有可能
I. Introduction In the 1920s and 1930s, the hybridization between indica and japonica was conducted by Kato Matsutake and Lu Shogun to study the genetic relationship of cultivated rice and to study the taxonomic character of cultivated rice. Since the early 1950s, indica and japonica crossbreeding at home and abroad has been a conscious breeding research. This study began in 1951 and has been for thirty years now. Recalling the past and looking forward to the future, our research on the ideal plant shape is an important study on the theory of high-yielding rice breeding in the future. It is possible that plant-type breeding is a practicable high-light efficiency breeding
