本文根据Ｅｂｅｒｈａｒｔ—Ｒｕｓｓｅｌｌ法和Ｔａｉ法设计了测定品种稳定性的程序，计算出Ｅｂｅｒｈａｒｔ—Ｒｕｓｓｅｌｌ法的１）品种对环境的反应参数－回归系数ｂｉ；２）稳定性参数－离线性回归的方差Ｓ２ｄ和Ｔａｉ法的１）品种对环境的直线响应α；２）直线效应的离差λ。输入一次原始数据可计算出两种方法的品种稳定性参数
According to Eberhart-Russell method and Tai method, we designed a program to measure the stability of varieties, and calculated the response parameters of environment to Eberhart-Russell’s method of 1) regression coefficient bi. 2) Stability parameter-variance of linear regression S2d And Tai law 1) variety of linear response to the environment α; 2) the linear effect of the deviation λ. Enter the original data to calculate the variety stability parameters of the two methods
