Abstract

Abstract:

In order to establish a comprehensive evaluation system for 54 large-flowered pompon type cut chrysanthemum lines,11 ornamental traits including plant height, internode length,stem diameter,stem filling degree,leaf length,leaf width,angle of leaf petiole,flower diameter,ratio of flower height vs flower diameter,ray florets number and tubular florets number were employed. The result showed that the ratio of flower height vs flower diameter is of the highest weight value,i.e.,0.241,which has the greatest influence on the pompon flower type,followed by number of ray flowers with a weight value of 0.155,and number of tubular flowers with a weight value of 0.111. K-Means cluster analysis showed that the 54 F₁ lines could be divided into 3 grades,i.e.,13 superior lines,30 good lines,and 11 poor lines,which accounted for 24.07%,55.56% and 20.37%,respectively,of the evaluated plant lines. The analytic hierarchy process and K-Means cluster analysis are effective in evaluating the ornamental performance of F₁ progeny of pompon type cut chrysanthemum,as well as to select excellent offsprings that meet breeding goals. The present study would provide valuable plant materials for the development of new pompon type cut chrysanthemum varieties.

Key words: chrysanthemum, cut flower, F₁ hybrid, analytic hierarchy process, morphological characters, comprehensive evaluation
