本文主要以黄淮麦区不同时期代表性大麦品种为试材，探讨了产量及其构成因素、形态性状、生育期等的演变规律，估计了遗传方差、遗传变异系数、遗传力、遗传进度、相对遗传进度等重要遗传参数，分析了主要性状之间的遗传相关。对大麦今后高产育种的主攻目标、性状改良潜力、理想株型育种等重要问题进行了讨论。
In this paper, the representative barley varieties from different periods in Huanghuai wheat area were used as materials to investigate the evolution of yield, its components, morphological traits and growth period. The genetic variance, genetic variation coefficient, heritability, genetic progress, Relative genetic progress and other important genetic parameters, analyzed the genetic correlation between the major traits. In the future, the main target of barley high yield breeding, the potential of trait improvement, the ideal plant type breeding and other important issues were discussed.
