层次分析法在三色堇观赏性评价中的应用

以33份三色堇种质为试材,采用层次分析法对其观赏性进行综合评价.三色堇观赏性评价的层次分析模型分为:目标层(综合观赏性)、准则层(株形,花,叶)和方案层(分枝数,株幅,株高,花期,花斑,花色,花数,花径,叶面积,叶长和叶宽).在准则层中,花的权重最大,其次为株形;在花的方案层中,花径的权重最大,其次为花数.构建的模型完整、合理、符合实际,适用于三色堇资源观赏性评价.33份三色堇材料观赏性评价结果表明,材料可分为3个等级,其中CYS-H3、229.11、229.19、EWO、HSY4-1观赏价值高,可优先选择利用.

Analytic hierarchy process on pansy ornamental evaluation

This paper used analytic hierarchy process(AHP) to appraise the ornament of 33 pansy cultivars.The analytic hierarchy process model established for pansy ornamental evaluation includes goal level,criterion Journal of Northeast Agricultural University level,and element level.The goal level refers to the integrated ornament of pansy.The criterion level included plant shape,flower and leaf.The element level contains branch number,plant width,plant height,florescence,blotch,flower color,the number of flower,the diameter of flower,leaf area,leaf length,and leaf width.In the criterion level,flower had the biggest weight,following plant shape;In the element level of flower,flower diameter had the biggest weight,following flower number.The AHP displays the character with integrity,rational,and according with practice,which suitable to pansy ornamental evalution.By the AHP,33 pansy cultivars could be classified into 3 grades.CYS-H3,229.11,229.19,EWO,HSY4-1 were grouped with the highest ornamental value for prior utilization in pansy breeding.
