随着农业生产水平的提高,需要培育亩产千斤以上的高产小麦新品种。而产量是一个复杂的数量性状,受其它许多性状的制约和影响,和其它性状之间存在着复杂的相关,并且产量的遗传力比较低,易受环境影响,早代选择不易见效,这就增大了育种难度。本研究对小麦主要农艺性状的表型相关、遗传相关、环境相关和遗传相关通径系数进行了初步分析,估测 With the improvement of the level of agricultural production, new varieties of high-yield wheat that need to produce more than one kilogram per mu will need to be cultivated. However, yield is a complex quantitative trait constrained by many other traits and has a complex correlation with other traits, and the heritability of yield is relatively low and susceptible to environmental impacts. Early generation options are not easy to be effective. Increased breeding difficulty. In this study, phenotypic correlation, genetic correlation, environmental correlation and genetically related path coefficient of major agronomic traits in wheat were primarily analyzed.
