傅瑞(K.J.Frey)氏此文是1971年出版1972年重版的论文集“离开产量的平台”一书中主要的一篇。作者回顾了几十年来产量育种上的成就,并在总结近年育种工作的基础上提出了自己的看法,有一些建议可供参考。但也有些地方分析问题不够全面,希望读者批判阅读,取其精华,去其糟粕。 K.J.Frey This article is published in 1971, reprinted in 1972, “a departure from the production platform,” a book in the main one. The author reviews the achievements made in decades of yield breeding and summarizes the breeding work in recent years based on his own views, there are some suggestions for reference. However, there are also some areas where the problem of analysis is not comprehensive enough, and we hope readers will read it critically, take its essence and go to its dross.
