从源库相互作用的原理出发,提出了一种判小麦品种源库状况的方法,并以此考察了20个不同来源和特性的小麦基因型的源库状况。描述小麦基因型源库状况的源库指数X的定义域为[-1,+1]。黄淮麦区推广品种的X值一般在-0.3～+0.3之间,说阳其源库关系基本协调。X值与千粒重有较密切的直线关系,从品种的千粒重大小可大致了解其源库状况。黄淮麦区源库协调的小麦品种千粒重应为38～40g。
Based on the principle of interaction between source and sink, a method for judging the status of source and sink of wheat cultivars was proposed, and the status of source and sink of wheat genotypes from 20 different sources and traits was investigated. The domain of the source library index X that describes the status of the source genotypes of wheat genotypes is [-1, + 1]. Huanghuai wheat varieties to promote the X value is generally between -0.3 ~ +0.3, said the source of its basic coordination of the source library. X values and 1000-grain weight has a more close relationship between the linear, from a thousand species of grain size can be roughly about the source of the library situation. Huanghuai wheat co-ordination of sources and sinks thousand grain weight should be 38 ~ 40g.
