采用3种不同分析方法,对2013年黄河流域棉花新品种测试体系的丰产性和稳产性进行分析,比较各分析方法的优劣。分析结果表明:变异系数法和稳定性参数法计算方法简单直观,易于理解;高稳系数法能把参试品种的丰产性和稳产性结合起来进行综合分析和评价,方法简便且接近生产实际。但各种分析方法均有不足之处,较好的方法是综合利用这3种不同的分析方法对棉花参试品种的丰产性和稳产性进行综合分析和评价,并进行多年多点试验。
Three different analysis methods were used to analyze the high yield and stability of the new cotton variety testing system in the Yellow River Basin in 2013, and to compare the advantages and disadvantages of each analytical method. The results show that the method of variation coefficient method and stability parameter method are simple and intuitive, and easy to understand. The high-stability coefficient method can combine the high yield and stability of the tested varieties for comprehensive analysis and evaluation. The method is simple and close to the actual production. However, all kinds of analysis methods have some shortcomings. The better way is to comprehensively use the three different analysis methods to comprehensively analyze and evaluate the high yield and stable yield of cotton varieties tested, and carry out multi-year multi-point experiments.
