Abstract: Ornamental evaluation is the important foundation for cross breeding. The Analytic Hierarchy Process (AHP) was used to evaluate the ornament of 30 Viola cultivars. The AHP model for Viola ornamental evaluation which consisted of the following three level: Target level, criterion level and index level. The target level is the comprehensive ornamental evaluation of Viola. The criterion level consisted of the three factors: Flower, leaf and plant shape. The index level includes branch number, plant width, plant height, flower color, the number of flower, florescence, blotch, the diameter of flower, leaf area, leaf length and leaf width. In the criterion level, flower with more weight; In the index of flower, flower diameter had maximum weight, next came flower number .The result showed The AHP method can provide scientific basis for Viola ornamental evaluation. About 30 Viola cultivars could be classified via AHP method into three grades. The CYS-H3, X1.11, X1.19, HSY4-1 possessed the highest ornamental value for prior utilization in Viola breeding.
