摘要:

在蓖麻品种的育成与推广过程中,品种产量性状的稳定性是一个重要影响因子。由于品种的基因型和环境存在着交互作用,用一般的线性回归方程只能解释小部分交互作用。主效可加互作可乘模型(AMMI模型),不仅最大程度地反应互作变异,而且能准确地分析品种的稳定性。本文应用AMMI模型及双标图对4个蓖麻杂交组合2008—2009年多点试验的产量性状进行稳定性分析,进而评价各参试组合的稳定性和适应性。

Abstract:

The stability of variety yield traits is an important factor in the process of castor variety breeding and promotion. The general linear regression equation can only explain a small part of the interaction due to the interaction between genotype of variety and environment. Addition main effects and multiplication interaction (AMMI) model not only response interaction variance, but also accurately analyze the stability of varieties. The yield stability of four castor varieties was analyzed with AMMI model and biplot using data from multi-point tests in 2008-2009, and then evaluated stability and adaptability of varieties.
