摘　　要：采用直接排序法、相对值排序法、平均隶属度法3种评价方法,对23个泰山板栗优系的单位树冠投影面积产量、单粒重、单粒重标准差、含糖量4个主要性状进行了综合评价。结果表明,3种方法对泰山板栗优系产量和品质的评价结果有一定差异,认为平均隶属度法是较科学、准确的方法。This article evaluates 4 main characters on yield and quality （unit projected area output, per chestnut weight and its standard deviation, and sugar content） of 23 chestnut superior varieties with three kinds of evaluation methods including direct evaluation, relative evaluation and average sub- degree evaluation. The results show that the three evaluation methods are different from each other and the average sub- degree method is more accurate than other two methods.
