摘　　要：运用混合线性模型的分析原理 ,对 1 996年和 1 997年的四川省油菜区域试验的产量结果 (非平衡数据 )进行统计分析。结果表明 ,影响油菜产量的随机效应方差分量中 ,年份—试点互作方差分量最大 ,表明 9个试点的产量表现在1 996年和 1 997年很不一致。多重比较分析表明 ,绵阳 92 -4 592和 94 0 7N比对照中油 82 1增产达极显著水平 ,这与线性对比分析结果相似。据回归参数和置信区间判断 94杂According to the theory of mixed linear model analysis, the yields of oil rape regional trails in Sichuan Province in 1996～1997 were analysed statistically.The results showed that year× location variance component had main effects on the yields.Multiple comparisons revealed that the yield differences between “Mianyang 92-4592' and “9407N' and control,that is ,“Zhongyou 821', were significant at the 1% level .The results were consistent with these obtained by linear contrast analysis.Regression parameter and confidence interval indicated that “94 Za-4” had better stability.
