1983—1986年度在江苏淮南地区多点测验了二组小麦品种。结果表明线性回归模型的测定效率受环境极差的影响。依据各参数的特性及其相关,众参数分为二组,分别测定品种产量对不同环境水平的响应及该响应的稳定性。产量、产量响应指数和稳定性参数间相关不显著,有可能选育到兼具高产、对高产环境响应敏感及产量稳定的小麦品种。 1983-1986 in Huainan in Jiangsu more than two groups of wheat varieties tested. The results show that the linear regression model of the determination of efficiency by poor environmental impact. According to the characteristics of the parameters and their correlations, the parameters were divided into two groups to determine the response of the varieties to different environmental levels and the stability of the response. There was no significant correlation between yield, yield response index and stability parameters, and it was possible to breed wheat varieties with high yield, sensitive to high yield environment and stable yield.
