用Eberhart-Russell的模式和方法分析了同原地区1982～1983年两年水地区域试验中5个春小麦品种产量的稳定性。结果表明:参试品种的bi参数值差异并不明显,而S_(di)~2参数值却有显著性差异。这证明衡量品种产量的稳定性必须用bi和S~2(di)两个稳定性参数一并分析。品种的平均产量与这两种稳定性参数之间并无相关性。产量构成因素的稳定性对品种的稳定性有较大的影响。参试的5个品种中,晋2148表现产量较高,适应性较好。通过本研究认为,利用这种模式和分析方法才能对参试品种的稳定性和适应性作出较全面的评价,为合理利用和推广提供依据。
Using Eberhart-Russell’s model and method, the stability of five spring wheat cultivars in the field trials in the two areas from 1982 to 1983 was analyzed. The results showed that there was no significant difference in the bi parameter between the tested cultivars, but there was a significant difference between the values of di2 and 2. This proves that the stability of the yield of the varieties must be analyzed together with the two stability parameters bi and S ~ 2 (di). There was no correlation between the average yield of varieties and the two stability parameters. The stability of yield components has a greater impact on the stability of varieties. Among the five cultivars tested, Jin 2148 showed higher yield and better adaptability. Through this study, we believe that the use of this model and analysis methods can make a more comprehensive assessment of the stability and adaptability of the tested varieties, and provide the basis for rational utilization and promotion.
