经过试验 ,用高稳系数法分析品种的高产稳定性 ,计算简便且分析容易 ,但比较粗放。回归系数座标分析法较为详细准确 ,缺点是比较繁琐。所以在对区试结果不需详细分析时 ,用高稳系数法较简便容易 ;如需详细分析时 ,则用回归系数座标分析法较准确可靠。同时对几种品种稳定性参数的准确性进行了比较分析 ,结果表明品种间回归系数的大小能较准确地反映出品种间稳定性差异程度的大小 ,其对稳定性的代表性要准确于其他稳定性参数
After testing, with high stability coefficient analysis of varieties of high yield stability, easy calculation and analysis, but more extensive. Regression coefficient coordinate analysis method is more detailed and accurate, the disadvantage is more complicated. So in the district test results without detailed analysis, the use of high stability coefficient method is relatively simple and easy; for a detailed analysis, then the regression coefficient coordinate analysis method is more accurate and reliable. At the same time, the accuracy of the stability parameters of several cultivars were compared and analyzed. The results showed that the regression coefficient between cultivars could accurately reflect the degree of stability differences between cultivars, and their representativeness of stability should be accurate Stability parameters
