近几年来对一些育种方法在小麦产量育种上的效率曾几次提出过疑问。在今年刚出版的一篇题名为“高产育种的新途径”的文章里,Fasoulas说过:“遗传学对植物育种的贡献不像应有的那么显著”。我们同意他的看法,但问题是:原因何在呢? 本文有两个目的:第一,就遗传学对育种贡献不够大的事实提出几点原因,第二,概括地介绍一种方法,它能在很大程度上克服在小麦和其他自交作物高产育种上的一些 In recent years several doubts have been raised about the efficiency of some breeding methods in wheat yield breeding. In an article just published this year entitled “A New Way to High Yield Breeding,” Fasoulas said: “The contribution of genetics to plant breeding is not as significant as it should be.” We agree with him, but the question is: why? The purpose of this article is twofold: firstly, to put forward several reasons for the fact that genetics did not make enough contributions to breeding; and secondly, to introduce in a general way a method that can To a large extent, overcome some of the high yielding breeding in wheat and other selfed crops
