摘要
作物品种区域试验中基因型和环境互作现象普遍存在,AMMI模型作为一种分析G×E互作关系的方法,可非常有效的补充现有区域试验分析方法的不足。AMMI模型中双标图和特殊互作效应值Dge的引人,为直观地、定量地估计试点对品种的分辨力及品种对试点的特殊适应性提供了一种非常有效的手段。通过时2001～2002年度黄淮旱地小麦区试结果进行分析,三条显著的主成分轴共解释了82.56％的互作平方和,品种洛旱2号和晋麦47属高产穗产型品种,天95-3产量校高但穗产性差,济旱6001、Q92-3074穗产性好但产量轻低,临旱619、小山211产量低而不穗;从AMMI双标图及互作效应值可看出高产类型品种中,洛旱2号除天水、黄骅、绛县试点外,具有广泛的适应性,天95-3则仅对天水、长武、成县试点有特殊适应性,长6154对铜川、鹤壁、绛县、洛阳有特殊适应性。
In the multilocational trials, the interaction between genotype and environment is very common. As an advanced approach to explore the G×E interaction, the AMMI model could compensate the shortage of common analysis motheds used for regional trial data analysis. The introduction of the double mark figure and the special interacting value (Dge) of AMMI model was useful to identify the discriminability of locations to varieties and the special adaptability of cultivars. By analyzing the data of dryland wheat regional trial in Huanghuai from 2001 to 2002 with AMMI model, three main significant components explained 82. 56% of G×E interaction. Based on the analysis with AMMI model, Luohan 2 and Jinmai 47 had a higher and stabler yield. Tian 95-3 had a higher but less stable yield, Jihan 6001 and Q92-3074 had a lower but stabler yield. Linhan 619 and Xiaoshan 211 had a lower and less stable yield. Luohan 2 had the widest adaptability in the experiment except Tianshui, Huanghua and Jiangxian while Tian 95-3 had a specific adaptablity to Tianshui, Changwu, and Chengxian, and Chang 6154 had a specific adaptability to Tongchuan, Hebi, Jiangxian and Luoyang.
