在蚕豆品种区域试验中,品种在各地点的表现很不一致,说明品种的基因型(G)和环境(E)存在交互作用,常用的G×E交互作用分析法约束性较强,解释G×E交互作用较少。主效可加互作可乘模型(简称AMMI模型)成功地将方差分析和主成分分析结合在一起,在常规的基因型和环境的加性模型中加入了乘积形式的交互作用,能更多地解释G×E交互作用。并且借助AMMI模型的双标图,能直观、具体和灵敏地表达各参试品种的稳定性和适应性。结合稳定性参数将AMMI模型应用于2004~2005年度云南省优质蚕豆新品种联合区域试验数据的分析,结果表明:应用AMMI模型分析蚕豆品种区域试验是一种行之有效方法。
In the regional test of broad bean varieties, the performance of the cultivars at different loci was very inconsistent, indicating that the genotypes (G) and environment (E) of the cultivars had an interaction effect. The common G × E interaction analysis method was more restrictive and explained G × E less interaction. The main effects plus additive multiplicative model (referred to as AMMI model) successfully combined analysis of variance and principal component analysis, in the conventional additive model of genotype and environment to add the product of the interaction, more Explain the G × E interaction. And with the aid of the double plot of the AMMI model, the stability and adaptability of the tested varieties can be expressed intuitively, specifically and sensitively. Combined with the stability parameters, AMMI model was applied to the analysis of the joint regional trial of high-quality broad bean varieties in Yunnan Province from 2004 to 2005. The results showed that using AMMI model to analyze the regional test of broad bean varieties was an effective method.
