摘要:

两系法杂交稻在挖掘水稻杂种优势、保障我国粮食安全方面意义重大,但至2025年5月,两系杂交粳稻国审品种仅10个,只占同期国审水稻品种数的0.23%。本文基于两系杂交粳稻的发展现状,总结了粳型两用核不育系选育的进展、粳型两用核不育系光温敏雄性不育遗传位点及机制,深入剖析了其发展远落后于两系杂交籼稻的原因,并针对性地提出了未来发展对策,旨在为推动两系杂交粳稻的选育与应用提供有益的建议和参考。

Abstract:

Two-line hybrid rice is of great significance in harnessing the heterosis of rice and ensuring China’s food security. By May 2025, there were only 10 national approved varieties of two-line hybrid japonica rice, accounting for just 0.23% of the national approved rice varieties during same the period. Based on the current development status of two-line hybrid japonica rice, this paper summarized the progress in the breeding of japonica dual-purpose genic male sterile lines and the genetic loci and mechanisms of photo-thermo-sensitive male sterility in japonica dual-purpose genic male sterile lines, and conducted an in-depth analysis of the reasons why its development lags far behind that of two-line hybrid indica rice. Furthermore, it puts forward targeted countermeasures for future development, aiming to provide valuable suggestions and references for promoting the breeding and application of two-line hybrid japonica rice.

Key words: two-line hybrid japonica rice, PTGMS line, research progress, prospect
