玉米轮回选择的目标是改变等位基因频率,从而改变群体均值,同时也可以改变基因型×环境(G×E)的互作(Moll等,1978)。通过某些类型的稳定性分析,比较不同环境条件下选育群体和原始群体的反应,能够鉴定出选择对G×E互作的影响。已经提出过几种测定基因型表现和环境的某些加性度量之间是否存在线性关系的稳定性 The goal of maize reincarnation is to change allele frequencies to change the population mean while also changing genotype × environment (G × E) interactions (Moll et al., 1978). Through some types of stability analysis, comparing the response of the breeding population and the original population under different environmental conditions can identify the effect of the selection on the G × E interaction. Several stability measures have been proposed to determine whether there is a linear relationship between some additive measures of genotype performance and the environment
