In order to make the index weight value in the comprehensive evaluation of fruit quality more scientific , and improve the objectivity and reasonability of the comprehensive evaluation results , analytic hierarchy process ( AHP) was used to determine the weight of each evaluation index , and a fruit quality index level library was set up , based on this calculation of each index score , and combined with the weight to calculate the comprehensive score . Finally, a comprehensive evaluation system of fruit quality was established .In this process, two scales of analytic hi-erarchy process (1-9 scale method and 0.618 scale method) were screened, and this evaluation system was applied to the selection of Huangguogan superior individual .The results showed that the 0.618 scale method could smooth each evaluation index , and when the evaluation index reached 5, the consistency of the judgment matrix constructed by the 0.618 scale method was significantly better than that of 1-9 scale method .Combined with the test datum , this experiment established Huangguogan fruit quality index level library .The fruit quality evaluation system was used to evaluate 162 Huangguogan plants , and 36 Huangguogan plants with excellent fruit quality were screened out .In the fruit quality evaluation system , it was more reasonable and accurate to use the 0.618 scale method to construct the judgment matrix .%为使果实品质综合评价体系中各指标权重值更加科学,综合评价结果更加客观、合理,该研究利用层次分析法确定各评价指标权重,建立一个果实品质指标水平库,并基于此计算综合得分,从而构建果实品质综合评价体系.在此过程中,对层次分析法标度进行筛选,最后,将此评价体系应用于黄果柑优良单株筛选.结果显示,0.618标度法能平滑各个评价指标,且当评价指标达5个时,0.618标度法的一致性优于1-9标度法.通过查阅文献和试验测定建立了黄果柑果实品质指标水平库,利用此果实品质评价体系评价了162株黄果柑单株,筛选出了36株果实品质优良的黄果柑单株.在果实品质评价体系中,使用0.618标度法构建判断矩阵所得权重值更准确.
