利用 4种不同的分析方法 ,对 1 999年河南省大豆品种区域试验各参试品种的丰产性、稳产性及适应性进行分析 ,结果表明 :用适定性参数法和变异系数法分析品种的丰产性及稳产性 ,可以从坐标图上一目了然 ;用高稳系数法分析品种的丰产性及稳产性可以从HSC位次中得出结果 ;用回归系数坐标法可以更清楚、更详细地说明各品种的丰产性及稳产性 ,但计算比较繁琐。适定性参数法、变异系数法、高稳系数法计算简便且容易分析 ,但比较粗略 ,对区试结果不需详细分析时 ,可应用其中任何一种方法 ,需要详细分析时 ,还是应用回归系数坐标分析法更为准确可靠
Four different analysis methods were used to analyze the high yield, stability and adaptability of the tested varieties in the regional experiment of soybean in Henan Province in 1999. The results showed that the yield Sex and stability can be seen at a glance from the chart; high stability coefficient analysis of high yield and stability of varieties can be derived from the HSC rankings; regression coefficient coordinates can be clearer and more detailed description of the varieties The high yield and stability of production, but the calculation is more complicated. Coefficient parameter method, coefficient of variation method, high stability coefficient method calculation is simple and easy to analyze, but relatively rough, the district test results without any detailed analysis, you can apply either method, the need for detailed analysis, or the application of regression coefficients Coordinate analysis method is more accurate and reliable
