摘要/Abstract

摘要：

杂交水稻为世界粮食安全做出了重要贡献。细胞质雄性不育和光/温敏不育分别是三系和两系杂交稻生产利用的遗传基础,而(亚)种间杂种不育则是杂交稻生产中要克服的主要技术瓶颈。因此,水稻育性调控是杂交水稻生产技术的关键,也是研究植物核质互作和物种生殖隔离等基础科学问题的重要模型。我国植物遗传学家在阐明杂交水稻育性调控的分子遗传基础领域做出了重要贡献。本文回顾了我国杂交水稻的发展历程,系统总结了杂交水稻生产涉及的细胞质雄性不育与恢复、光/温敏不育与育性转换、杂种不育与亲和性的遗传基础和分子作用机制,探讨了我国杂交水稻生产存在的问题,指明了水稻杂种优势利用的发展方向。

Abstract:

Hybrid rice has contributed greatly to global food security. Cytoplasmic male sterility (CMS) and photo/ thermo sensitive genic male sterility (P/TGMS) are genetic bases for three-line and two-line hybrid rice production, respectively. In contrast, (sub-) specific hybrid sterility (HS) is a major barrier for utilization of hybrid vigor of distant hybrid rice. Therefore, understanding the molecular regulatory mechanism of rice fertility is a key technical issue for hybrid rice industry, and a long-standing basic scientific issue for nuclear-cytoplasmic interaction and reproductive isolation. Chinese geneticists of plant sciences have made tremendous contributions on the molecular genetic basis of rice fertility related to hybrid rice production. Here, we review the development of hybrid rice production systems in China and summarize current advance on genetic basis and molecular mechanism of CMS, P/TGMS, and HS involved in hybrid rice. We also discuss problems of hybrid rice production in China and point out new direction for future utilization of heterosis in rice.

Key words: hybrid rice, cytoplasmic male sterility, hybrid sterility, photo/thermo sensitive genic male sterility, fertility restoration
