夏大豆品种区域试验4种分析方法的比较研究

Comparative Study on the Four Analysis Methods for Summer Soybean Variety Regional Test

[目的]筛选更加简便、快捷、有效分析夏大豆品种区域试验的方法。[方法]采用方差分析、灰色关联度、同异分析和模糊概率法,对2015年国家黄淮海地区夏大豆品种(南片B组)试验资料进行了比较分析。[结果]4种分析方法各有优点,方差分析法理论和方法虽然较成熟,但只能分析产量1个性状,综合能力较差;其余3种分析方法综合能力较强,对参试种评价较为客观全面。[结论]模糊概率法区分度较高,更有利于辨别品种优劣;其计算简便快捷、结论准确可靠,较适合用来综合评价夏大豆新品种。

[Objective] To exploit more convenient, fast and effective methods for experimental analysis of summer soybean variety regional test.[Method] The results of national summer soybean regional trials in Huang-Huai-Hai region in 2015 were adopted. And four different analysis methods of variance analysis, grey correlation analysis, similarity-differnce analysis and fuzzy probability method were used and compared.[Result] Each of the four analysis methods had its own merits. The theory and procedure of variance analysis was applicable, with good results only for single character and without integrated functions;the remaining three analysis methods were with integrated functions and more objective and comprehensive to varieties evaluation.[Conclusion] The fuzzy probability method was better in differentiability, more conductive to identify the quality of varieties, more simple and convenient for calculating, and had more accurate and reliable conclusion. Thus, it can be regarded as a good method for comprehensive evaluation of summer soybean varieties.
