摘要:

不育系是杂交水稻的“芯片”,不论三系法还是两系法,品种的不断突破都取决于不育系种质的发现与持续创新。自水稻光敏核不育种质农垦58S被发现以来,水稻两系法杂种优势利用研究已历经50年,目前两系法杂交水稻已占据我国杂交水稻半壁江山。作者通过总结我国水稻光温敏两用核不育系选育历程、取得的主要成就,以及作者团队在制种安全实用籼型水稻温敏两用核不育系创制方面取得的一系列进展,提出未来实用型水稻两用核不育系育种的主攻方向。

Abstract:

The sterile line is the “chip” of hybrid rice. No matter the three-line or the two-line hybrid rice, the continuous breakthrough of rice variety development depends on the discovery and continuous innovation of sterile line germplasm. Since the discovery of Nongken 58S, a photoperiod sensitive male-sterile rice(PGMR), the two-line hybrid rice has occupied half of the area of hybrid rice extension in China after 50 years research. In this paper, we summarized the breeding process and main achievements of the photoperiod/thermo- sensitive genic male-sterile(P/TGMS)lines in China, as well as our progresses of TGMS lines development, and put forward the main direction of research and development for future P/TGMS lines.

Key words: rice, two-line hybrid, TGMS, germplasm creation
