不同分析方法在谷子区试丰产性与稳产性分析中的应用

应用高温系数、非参数统计和稳定性参数法等分析方法与多点试验中常用的统计方法,对2004-2005年国家谷子品种区域试验(华北夏谷区组)汇总试验结果进行综合评价和比较。结果表明,各种统计方法分析结果反映出的大致趋势相同,只是个别结果有所差别;应用高温系数或非参数统计与稳定性参数结合的方法能包含更多信息,使分析结果更具说服力。

Application of Different Methods in Analysis on Productivity and Stability of Millet in Regional Trial

Using high temperature coefficient,non parameter statistics,stability parameter methods,and commonly used statistical methods in multi-point test,the summary of test results of National Millet Variety Regional Test(North China summer Millet Group)during 2004 to 2005 were comprehensive evaluated and compared.Results showed consistent tendency by a variety of statistical methods,except for a few results.The combination of high temperature coefficient or non parameter statistics with stability parameters methods could contain more information,and made the results more convincing.
