摘    要:AMMI模型发展了分析基因型与环境互作的统计方法,但缺乏度量品种稳定性的定量指标。本文提出一个度量品种稳定性的新参数Di。实例分析表明,Di与生态价方法和稳定性方差法的分析结果有很好的一致性。讨论了AMMI模型在分析品种稳定性方面的意义以及应用新参数时应注意的问题。

关 键 词:AMMI模型  基因型  环境  互作  稳定性  育种

Abstract:The Additive Main Effects and Multiplicative Interaction (AMMI) model has developed a new statistical method for analyzing the genotype by environment interaction. How ever, there is no quantitative criterion for evaluating stability differences among varieties in the AMMI analysis. The new parameter, Di, has been proposed to measure the stability of variety based on the AMMI analysis in this paper. The results of an applied example indicated that the estimates of Di were greatly concordant with the estimates of ecovalue and stability variance. Im plications and relevant questions were also discussed for the application of the AMMI analysis.
