应用品种“稳定性参数”的估算方法分析了 1 997～ 1 998年度山西省冬小麦南部中水肥区试 1 1个参试品种 (系 )的高产稳产性 ,并对计算方法和计算结果进行了评价分析。结果表明 ,“稳定性参数”的坐标分析法是分析小麦新品种 (系 )的高产稳定性更为准确有效的方法 ,此法将对参试品种 (系 )做出定量化的准确评价 Application of “Stability Parameter” Estimation Method The high yield and stability of 11 tested varieties (lines) in the mid-winter wheat fertilizer trial in Shanxi Province during 1 997-1988 were analyzed. The calculation methods and calculation results were also evaluated analysis. The results showed that the coordinate analysis method of “stability parameter” was a more accurate and effective method to analyze the high yield and stability of new wheat varieties (lines). This method will make accurate quantitative evaluation of the tested varieties (lines)
