“二系法制种”是利用光敏核不育系在某种特定光温条件下的雄性不育特性,与恢复系配制生产杂交稻种子;同时又利用它在一定条件下表现为雄性可育,能自交结实的特性,繁殖不育系种子。它能一系两用,比三系法简单、种子成本低、且配组自由。二系杂交水稻一般比三系杂交水稻增产10%~30%, “Two-line system of law” is the use of photosensitive nuclear sterile lines under certain light and temperature conditions of male sterility, and restorer system formulated hybrid rice seeds; at the same time it is used under certain conditions showed male fertile, To self-actual features, breeding sterile seed. It can be a series of dual-use, simple method than the three lines, seed cost is low, and with the group free. Second-line hybrid rice generally yield 10% to 30% more than three-line hybrid rice,
