本文利用1962～1964年黄淮冬麦区区域试验17个环境,6个品种的资料分析了所选取的9种不同的评价品种稳定性方法。每种方法都可以得出一种品种稳定性序列。然后比较9种不同方法的结果以及与品种实际推广情况的差异,同时从理论上分析它们的优劣。结果表明这些方法在确定品种稳定性方面作用相似。回归法较非回归法精确。在回归中,Eberhart 和 Russell 法比较简单。非回归中 Francis 法比较简单方便。本文建议将稳定性参数单位化,以便不同品种稳定性参数间直接比较。
In this paper, 1962 ~ 1964 Huanghuai winter wheat regional test of 17 environments, 6 varieties of data analysis of the selected nine different evaluation of the stability of the method. Each method leads to a species stability sequence. Then compare the results of 9 different methods and the actual promotion with the species differences, at the same time from the theoretical analysis of their advantages and disadvantages. The results show that these methods play similar roles in determining the stability of breeds. Regression method is more accurate than non-regression method. The Eberhart and Russell laws are simpler in the regression. The non-return Francis method is relatively simple and convenient. In this paper, it is suggested to unitize the stability parameters so as to directly compare the stability parameters of different varieties.
