Abstract:

In order to improve the evaluation system of Hydrangea germplasm, this study took 25 introduced Hydrangea varieties as test materials, quantified the evaluation indexes of adaptability, stress resistance and ornamental value of Hydrangea varieties by means of observation records and morphological data measurement, analyzed the quantitative characters with genetic variability as the breakthrough point, and comprehensively evaluated and ranked the materials by cluster analysis combined with analytic hierarchy process. The results showed that cutting survival rate, flower color adjustability and the number of small flowers per inflorescence played a leading role in the evaluation. The results of cluster analysis and hierarchical classification were consistent in the evaluation system, and the scientific and effective results could be confirmed by analyzing the data. The evaluation results of seven Hydrangea varieties, Mangekyou, Komatsu, Camilla, Your feelings and mine,Popcorn, Mohuan crystal and The eternity of you and me, reached Grade I. These varieties have the common characteristics of adjustable colors, large crown width, more small flowers in a single inflorescence, higher cuttage survival rate, upright or semi-upright plant type and strong stress resistance.

Key words: Hydrangea, germplasm evaluation, variability analysis, cluster analysis, analytic hierarchy process
