摘要
应用AMMI模型对8个甘蓝型优质油菜新品种(系)区试产量进行了分析。结果表明:AMMI模型解释基因型与环境互作明显优于线性回归模型。通过AMMI1模型双标图可以看出产量在品种和地点间的变异程度,找出稳定性较好的品种。从AMMI2双标图上可以找出与每一个地点产量互作最大的品种。
The additive main effects and multiplicative interaction (AMMI) model and its biplots were used to analyze the data of elite rapeseed varieties in the regional trials at 9 sites carried out in Sichuan province in 1997-1998. The results showed the AMMI model is superior to the conventionally adopted regression analysis in interpreting G x E interaction. Variation of yield of different varieties and at different sites could be clearly shown on the biplots of AMMI and varieties with good adaptability could readily be identified. In addition, the varieties which showed greatest interaction with a given site could be found by the biplots of the AMMI model.
