用Eberhart和Russell法计算了7个小麦品种的回归系教和离回归均方两个参数;根据离回归均方不显著时,回归系数可用来估计品种稳定性的原理,对7个品种进行了产量的稳定性评价:豫西832和洛阳841是高产稳产的小麦新品种。並对Eberhart和Russell法与Finlay和wilkinson法进行了比较,结果说明后者方法简便但可靠性不如前者,且较详细地介绍了Eberhart和Russell法的分析程序。
Using Eberhart and Russell method, the regression coefficients of seven wheat cultivars were calculated and two parameters of return-to-mean-square were calculated. Based on the principle that the regression coefficient can be used to estimate the stability of cultivars when the mean-square was not significant, seven cultivars Yield stability evaluation: West Henan 832 and Luoyang 841 are new varieties with high and stable yield. The comparison between Eberhart and Russell’s method and Finlay’s and Wilkinson’s method shows that the latter method is simple and less reliable than the former, and the Eberhart and Russell method’s analysis procedures are introduced in more detail.
