Abstract

Abstract:

Total number of eight qualitative traits related to flower branch characteristics including stem height uniformity,stem strength,stem filling degree,flower branch angle,flower horizontal curvature,flower vertical distribution,flower horizontal convergence,flower branch hardness of 188 commercial varieties of cut chrysanthemums were observed and classified in this experiment. The traits were evaluated based on grey relational analysis. The results indicated that the weighted values of eight factors which were determined by grey relational analysis showed flower horizontal convergence,stem strength,flower branch hardness,flower branch curvature had the most important pact on the evaluation,and the values were 0.1524,0.1430,0.1312,0.1261,respectively. Five excellent varieties of ZQ2-83,Q6-12,Q3-8,Q1-31 and Q4-13 were screened via grey ralational analysis,their weighted correlations were all greater than 0.8000. Then the 188 varieties were divided into four grades by cluster analysis,there were excellent,good,medium,and poor varieties which accounted for 9.04%,26.06%,50.00% and 14.89%,respectively.

Key words: cut chrysanthemum, branch characteristics evaluation, qualitative traits, grey relational analysis, cluster analysis
