AMMI模型在玉米区域试验中的应用

Application of AMMI Model in Regional Experiment of Maize

采用AMMI模型对2003年黄淮海夏玉米品种区域试验(二)组的试验数据进行分析。结果表明,3条显著的主成分轴共解释了56.91%的互作平均产量;X1132X和农大108属于高产、稳产型品种,适应性广;中科1号平均产量较高,稳定性较好;农华022、DH3631平均产量较低,稳定性较好。从AMMI模型互作效应结果看出,河北省永年、江苏省连云港、河南省濮阳、河南省郑州试点对品种的分辨力较强;山东省长青、陕西省泾阳、山东省德州、河南省洛阳试点对品种的分辨力较弱。X1132X除在江苏省连云港、河南省睢县、安徽省宿州、山西省绛县、河南省宝丰外,具有广泛的适应性;DH2101在山东省长青具有特殊适应性。

In this paper,the AMMI model was applied to analyze the data of 2003 summer maize regional experiment. And the result showed that 3 significant principal constituent axles explained 56.91% interact sum of square. With the high yield and stable varieties of X1132X and Nongda108, they were extensive adaptability. Zhongkel 1 was higher average yield and better stable. Nonghua022 and DH3631 were lower average yield and better stable. The result also indicated that varieties in the test locations of Yongnian in Heibei Province, Lianyungang in Jiangsu Province, Puyang and Zhengzhou in Henan Province expressed stronger resolution power. Changqing and Dezhou in Shandong Province, Jingyang in Shaanxi, Luoyang in Henan Province expressed weaker resolution power. X1132X showed extensive adaptability except in Lianyungang, Shuixian, Xuzhou, Jiangxian and Baofeng. DH2101 showed special adaptability in Changqing of Shandong Province.
