长穗颈双低温敏核不育水稻的选育
Development of TGMS Rice with eui-Gen e Coincided with Double Low Critical Temperature
摘要
Abstract
TGMS line with double low critical temperatur e were treated by 350 Gy 60 Co γ-ray.After when M1 gen eration ha d been subjected to the natural low temperature in the fertility sensitive stage of TGMS and self-propagated, 250 000 M2 plants were trans planted in individual or double plants. Seven mutants with eui-gene and double low critica l temperature were selected successfully from M2 population. Thus important p rogress in seed production of two-line hybrid rice was achieved by this study,n amely,the pr oblems related with the fluctuation of TGMS rice and overuse of gibberellic Acid (GA3).关键词
