提高作物产量是育种工作者追求的目的之一.高粱产量是品种基因型与环境互作的结果,其中产量性状属数量性状,受多基因控制,很多性状对其有促进或制约作用.并且这些性状间存在着不同程度的连锁,反映出不同程度的相关性,从而为高粱育种工作提供了丰富的内涵.为此,本文结合田间试验工作,对25个高粱亲本11个主要性状间的相互关系进行了表型、遗传和环境相关及通径分析.
Increasing crop yield is one of the objectives sought by breeders.The yield of sorghum is the result of interaction between genotype and environment of the cultivars, among which the yield traits are quantitative traits, controlled by multiple genes and many traits promote or restrict them. There are different degrees of linkage between traits, reflecting different degrees of correlation, thus providing abundant connotation for sorghum breeding work.Therefore, in this paper, field experiments, the relationship between 11 main traits of 25 sorghum parents Phenotypic, genetic and environmental related and path analysis were performed.
