大麦的主要农艺性状大都属于数量性状,受微效多基因控制,易受环境条件的影响,在杂种分离世代中,个体性状呈现连续分布,这给正确地配组和有效地选择带来了一定的困难。运用数量遗传研究方法对大麦农艺性状的遗传力和遗传进度进行估测,可以衡量遗传和环境影 Most of the main agronomic traits of barley belong to the quantitative traits, which are controlled by the micro-effective polygenes and are easily affected by the environmental conditions. In the hybrid segregation generation, the individual traits show a continuous distribution, which brings a certain amount of proper allocation and effective selection Difficulties. Using quantitative genetic methods to estimate the heritability and genetic progress of agronomic traits in barley, we can measure genetic and environmental effects
