用变异系数法、回归系数法和AMMI模型Dj值法对云南玉米区域试验点区辨力进行了比较研究,结果表明:回归系数法不很有效,变异系数法和AMMI模型法的结论大体相近,但AMMI模型Dj值法相对更准确。
By using the method of coefficient of variation, regression coefficient and AMMI model Dj value method, the discriminant power of Yunnan corn regional pilot is compared. The results show that the regression coefficient method is not very effective, the coefficient of variation coefficient method and AMMI model method are generally similar, However, AMMI model Dj value method is relatively more accurate.
