水稻超高产育种是当今世界的热门，也是难题．沈阳农业大学稻作研究室积多年以来的实际经验，早就致力于此，并已在１９８７年国内外刊物上有所讨论，首先提出理想株形与优势利用相结合的大方向．嗣后汲取各家之长，采用“偏矮秆”与“偏大穗”的材料试验不理想，又由“两偏”转向“三好”（植株高矮好，稻穗大小好和分蘖力强弱好）．经１９９１～１９９３年的验证，特别是１９９３年辽中县示范”三好一号”的验证，认为在理论上由“两好”转向“三好”是杂交后代选择标准的进一步完善，具有学科开拓性；在实践上，３年便有小成，改变了步履艰难的局面，也有要而不烦的实用性．本研究并且可能是自发地运用现代的控制理论于水稻育种的首例．
Super-high-yielding rice breeding is a hot topic in today’s world and also a problem. Shenyang Agricultural University Rice Research Institute accumulated over the years of practical experience, has long been committed to this, and has been in the 1987 domestic and foreign publications are discussed, the first proposed ideal combination of advantages and advantages of the general direction. Later learn from the length of each, the use of “partial dwarf” and “big spike” material test is not ideal, but also from “two partial” to “three good” (good plant height, good rice size and good tillering ability ). After the verification of 1991-1993, especially the demonstration of “Sanhao No.1” in Liaozhong County in 1993, it is considered that in theory, the change from “two goodies” to “three goods” is the further improvement of the selection criteria for future generations of hybrids, In practice, there will be a small three years, changing the difficult situation of walking, but also not to be annoying and practical. This study may also be the first case of rice breeding that spontaneously uses modern control theory.
