【摘要】 运用线性回归Eberhart和Russell模型、主效可加互作可乘(AMMI)模型以及高稳系数法(HSC)同时分析2002~2003年度重庆市油菜新品种区域试验参试组合的产量稳定性,对3种评价品种稳定性的方法进行了比较。结果表明,线性回归Eberhart和Russell模型和高稳系数法(HSC)可以为选择高产、稳产的油菜新品种提供有益的参考,但两者都有不足之处;AMMI模型通过从加性模型的残差中分离模型误差与干扰,可以提高估计的准确性,并且借助于双标图可以直观地描绘和分析基因型与环境互作的模式;三者中,AMMI模型是一种较为理想的品种稳定性评价方法。更多还原

【Abstract】 The Eberhart&Russell regression model,additive main effect and multiplicative interaction(AMMI) model,and high and stable coefficient(HSC) method were compared for analyzing the yield stability of rape varieties in the regional trial in Chongqing in 2002~2003.The results showed that the Eberhart&Russell regression model and HSC could propose effective information to be used for selecting rape varieties with high and stable yield although existing some improperiety,and AMMI was the convenient model with improving the estimate precision by isolating the error and interaction from remnant error in the additive model.AMMI is the relative ideal method for evaluating variety stability compared with the Eberhart&Russell regression model and HSC.更多还原
