Evaluation of Testing Environments in Winter Wheat

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 。

Testing environmental quality were evaluated on six sets of environments from 1985 through 1989 and nine sets of environments from 1990 through 1994. Ten or twelve genotypes were grown in each set and in each year. The evaluative model proposed by Brown K D is a linear regression. The results suggest that a set has a high regression coefficient is better able to discriminate between genotypes.
