借助AMMI模型分析了2009年国家西瓜品种区域试验中的产量数据，结果表明：基因型与环境的互作效应小于基因效应和环境效应，但是也达到了极显著的水平，而且基因型的效应占比例较大，其次为环境效应。不同西瓜品种在各试点的品种稳定性和不同试点对品种的分辨力差异较大：品种G4（09-N2）的稳定性参数最大（Dg＝15．53360），G7（09-N9）的稳定性参数最小（Dg＝2．56881）；8个西瓜品种中高产稳产的品种是G2（09-N1）和G1（09-N7），产量低且不稳定的品种是G4（09-N2）和G6（09-N12），产量高而稳定性一般的品种是G8（CK ，09-N15），产量低而稳定的品种是G7（09-N9），产量一般且稳定性一般的品种是G3（09-N5），产量一般稳定性差的品种是G5（09-N8）；在4个参试点中，甘肃兰州试点对品种的分辨力强，宁夏中卫试点和宁夏中宁试点对西瓜品种的分辨力一般，宁夏海原试点对品种的分辨力较差。
藉助AMMI模型分析瞭2009年國傢西瓜品種區域試驗中的產量數據，結果錶明：基因型與環境的互作效應小于基因效應和環境效應，但是也達到瞭極顯著的水平，而且基因型的效應佔比例較大，其次為環境效應。不同西瓜品種在各試點的品種穩定性和不同試點對品種的分辨力差異較大：品種G4（09-N2）的穩定性參數最大（Dg＝15．53360），G7（09-N9）的穩定性參數最小（Dg＝2．56881）；8箇西瓜品種中高產穩產的品種是G2（09-N1）和G1（09-N7），產量低且不穩定的品種是G4（09-N2）和G6（09-N12），產量高而穩定性一般的品種是G8（CK ，09-N15），產量低而穩定的品種是G7（09-N9），產量一般且穩定性一般的品種是G3（09-N5），產量一般穩定性差的品種是G5（09-N8）；在4箇參試點中，甘肅蘭州試點對品種的分辨力彊，寧夏中衛試點和寧夏中寧試點對西瓜品種的分辨力一般，寧夏海原試點對品種的分辨力較差。

The AMMI model was adopted to analyze the output data of watermelon varieties in regional trial in 2009 . The results showed that the genotype effect (G) accounted for the largest proportion ,followed by the environment effect (E) ,while G × E interactive effect was the smallest but still reached extremely significant level .There were significant differences in stability of the eight varieties and resolution of the four testing sites .Among the eight varieties ,the stability parameter of G4 (09 -N2) was the highest (Dg = 15 .53360) and that of G7 (09 -N9) was the lowest (Dg =2 .56881);G2 (09-N1) and G1 (09-N7) were the varieties with high -yield and high-stability ,G4 (09-N2) and G6 (09-N12) were the varieties with low-yield and low-stability ,G8 (CK ,09-N15) was the variety with high-yield and mid-stability ,G7 (09-N9) was the variety with low-yield and high-stability ,G3 (09-N5) was the variety with mid-yield and mid-stability ,and G5 (09-N8) was the variety with mid-yield and low-stability .As for the four testing sites ,Lanzhou (in Gansu) was the site with a powerful resolution of watermelon varieties ,Zhongwei (in Ningxia) and Zhongning (in Ningxia) were the sites with a moderate resolution ,and Haiyuan (in Ningxia) was the site with a poor res-olution .
