| 摘 要： | 用品种稳定性参数和高稳系数分析了1994－1995年度全国北方春玉米区试资料,同时对几种品种稳定性参数的准确性进行了比较分析,结果表明品种间回归系数的大小能较准确地反映出品种稳定性差异的程度。其对稳定性的代表性要准确于其它稳定性参数;用回归系数坐标分析法较为详细准确,但较繁琐。用高稳系数法分析品种高产稳产性简便可行,结果可靠,生产实践证明,分析结果与生产实际相吻合。

| Abstract: | The regional test data of spring maize in north China in1994～1995 were analyzed with cultivar stability parameter and high stable coefficient method and the accuracy of stability parameter of several cultivars was also analyzed.The results showed that the regression coefficient between cultivars can reflect the stability differences of cultivars accurately and the representativeness of its stability is accurater than other stability parameter;regression coefficient method is accurater and detailed,but miscellaneus.High stable coefficient is simple,feasible and reliable the practice proves that the results analyzed with the method coincides with the practice. |
