Theories and Methods of Rice Breeding for Maximum Yield

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.

Rice breeding for maximum yield is a global hot topic and tremendous challenge. For China, which has the largest population in the world and where rice is a staple food, increasing rice production is of vital importance. But the higher and higher the yield we seek, the more and more difficulties we meet. Since there is no ready theory and method for us to follow, we have to grope thrcugh trial and error. In this paper the authors attampt to make a comprehensive and systematic analysis of the valuable experiences acquired by rice researchers and growers through decades of painstaking labor, in a bid to f ur-ther refine the theories and methods in rice breeding for maximum yield and the criteria for hybrid progeny selection.
