Abstract: Rice breeding for maximum yield is a hot topic today in the world and a tremendous challenge as well. China's population is now approaching 1. 2 billion people. It is a country where rice constitutes a lion's share in grain production. The higher and higher the yield we seek, the more and more difficult the task will be. It is a breeding for maximum yield. Since there is no ready theory and method for us to follow, we have to grope along through trial and error. In this paper, the author attempts to make a comprehensive analysis of and systemize the valuable experience acquired by so many people through decades of painstaking labor, in order to further refine the theories and methods for combining ideal plant morphology with the utilization of vigor, as well as for optimized conbination of traits and criteria for selecting hybrid progeny put forward in the past, for reference and trial application by colleagues at home and abroad.

Key words: criteria for selecting hybrid progeny, ideal plant morphology, optimized combination of traits, the utilization of vigor

摘要： 水稻超高产育种是当前世界性的热门课题，也是难题。现在我国人口已近十二亿，水稻是我国粮食生产的大头。高产更高产，难度越来越大。它的超高产育种，既无现成的理论和方法可循，就只能摸索前进。本文试图将几十年来多少人的汗水心血所凝成的宝贵经验，全面加以分析整理，藉以进一步完善过去所提出的理想株形与优势利用相结合的大方向，优化性状组配以及杂交后代选择标准等理论和方法，以供国内外同行参考试用。
