本文系统介绍了我所１９９０年以来开展水稻两用核不育系生态育种的基本思路，育种程序，技术关键与要点，以及取得的成效。技术关键是在强大的长日低温（约２３℃）选择压力下选完全不育株，再在再生和／或短日条件下选可育株。育种成效主要是首次发现可达生产应用程度的核不育系再生复育特性，成功培育出蜀光６１２Ｓ和５７０Ｓ等有实用价值的核不育系。本文还提出了利用再生复育特性来培育育性表达完全或几乎不受浊、光环境因子影响的新型水稻两用核不育系的构想。
This article systematically introduces the basic ideas, breeding procedures, key technologies and key points of the ecological breeding of rice dual purpose nuclear sterile lines since 1990, and the achievements made. The key technical point is the selection of fully sterile plants under the conditions of a strong long-term low temperature (about 23 ° C) selection pressure and the selection of fertile plants under conditions of regeneration and / or short day. Breeding success is mainly found for the first time to reach the level of production and application of sterile lines of reproductive and reproductive characteristics, successfully cultivate Shu Guang 612S and 570S and other practical value of the male sterile lines. This paper also proposed the use of regenerative and reproductive traits to develop fertile expression of complete or almost no turbidity and light environmental factors affect the concept of a new type of rice dual-purpose nuclear lines.
