摘要:

选取188个切花小菊(Chrysanthemum morifolium)商业品种,对其主茎长整齐度、主茎强度、主茎充实度、花枝角度、花枝曲直、花朵垂直分布、花朵水平聚拢程度和花枝韧性等8个与枝性相关的质量性状进行观测、分级,采用灰色关联度分析进行综合评价。结果表明,利用灰色关联度分析计算出的8个性状权重值中,花朵水平聚拢程度、主茎强度的权重值最大,分别为0.1524和0.1430,其次是花枝韧性和花枝曲直,权重为0.1312和0.1261,说明这4个指标对菊花品种综合评价影响较大;筛选出‘ZQ2-83'、‘Q6-12'、‘Q3-8'、‘Q1-31'和‘Q4-13'5个花枝性状优良品种,加权关联度均为0.8000以上。通过系统聚类分析将188个品种分成花枝性状优、良、中、差4个级别,分别占评价整体的9.04%、26.06%、50.00%、14.89%。

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
