用 198 4～ 1989年度 6个环境和 1990～ 1994年度 9个环境的资料对试验环境的质量进行评估。评价模型是BrownKD提出的一个线性回归模型。试验结果表明 ,具有高的回归系数的地点可能对基因型有较高的辨别能力
The quality of the test environment was assessed using data from 6 environments from 198 4 to 1989 and 9 from 1990 to 1994. The evaluation model is a linear regression model proposed by BrownKD. Experimental results show that locations with high regression coefficients may have a higher genotypic discrimination
