大豆区试中品种的丰产性、稳产性及适应性分析方法比较

利用4种不同的分析方法，对1999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。

Comparison of Analysis Methods on High-yield , Stability and Adaptability of Soybean Varieties

In this article four different analysis methods are applied to analyse high yield , stability and adaptability of soybean varieties tried in 1999 region trial of Henan .The results indicated thathigh yield and stability of soybean can be clear at a glance from the coordinate picture with the adaptable and stable parameter law and the variation coefficient law ; high yield and stability of soy bean can reach the result from HSC's precedence if the high steady coefficient law is applied ; they can be clearer if the recurrence coefficient coordinate law is applied ,but calculation is complex .Calculation is simple and they can be analysed easily if the adaptable and stable parpmeter law , the variation coefficient law and the high steady coefficient law are applied , but the result is fairly rough . Among them any method can be applied when the result needn`t be analysed detailedly. When it needs to be analysed detailedly , the recurrence coefficient coordinate analysis law is reliable.
