1、一、可重复单因素随机区组试验设计8个小麦品种的产比试验，采用随机区组设计，3次重复，计产面积25平米，产量结果如下，进行方差分析和多重比较。表1小麦品比试验产量结果（公斤）品种区组产量1110.92110.83111.1419.15111.86110.17110819.3129.12212.33212.54210.75213.96210.67211.58210.41312.223143310.54310.15316.86311.87314.18314.41、打开程序把上述数据输入进去。2、执行：分析-一般线

2、性模型-单变量。3、将产量放进因变量，品种和区组放进固定因子。4、单击模型，选择设定单选框，将品种和区组放进模型中，只分析主效应。5、在两两比较中进行多重比较，这里只用分析品种。可以选择多种比较方法。6、分析结果。主体间效应的检验因变量:产量源III型平方和df均方FSig.校正模型61.641a96.8494.174.009截距3220.16713220.1671962.448.000区组27.561213.7808.398.004品种34.08074.8692.967.040误差22.972141.64
