小麦亩产量由亩穗数、每穗粒数和千粒重三个因素构成,但因自然条件和品种特性的不同,对产量的影响也各不相同,而且随着生产水平的提高,影响效应又是不断变化的。弄清这一点,对小麦生产和育种都有现实意义。本文应用多元回归和通径分析方法,对小麦产量构成因素的影响效应进行分析,以期为本地区小麦生产和育种提供信息。 The yield of wheat per mu consists of three factors: the number of ears per panicle, the number of grains per spike and the weight of one thousand grains. However, due to the differences of natural conditions and varieties, the yield of wheat also varies. And with the improvement of production level, the effect is Changing. To understand this point is of practical significance to wheat production and breeding. In this paper, multiple regression and path analysis methods were used to analyze the effects of wheat yield components in order to provide information for wheat production and breeding in this region.
