摘要
应用高稳系数法和常用分析方法相结合,分析了黑龙江省小麦区域试验14个参试小麦品种(系)的丰产稳产性,并将几种稳定性参数进行了比较和相关分析。结果表明:参试品种的标准差(S)、变异系数(CV)和回归系数(b)仅反映产量的稳定性,而与产量高低无关;高稳系数(HSC)能综合地评价品种的丰产性和稳产性,而且应用时比较简便,若能与回归系数法相结合,则能进一步提高分析的准确性。
The
yield and its stability of 14 spring wheat varieties in regional trials of Heilongjiang province
were analysed with the method of High stable Coefficient (HSC) Method and common analytic
method. Some stability parameters were compared and analysed for correlation. The results
indicate that the standard deviation, coefficient of variability and regression coefficient of
testing varieties can only reflect the stability of yield and have nothing to do with the highness
of yield. The HSC can synthetically and easily evaluate the yield and its stability of varieties.
With combination of HSC and regression coefficient the accuracy of analysis can be improved.
