以“中国菊花种质资源保存中心”保存的950个切花小菊(Chrysanthemum morifolium)品种的13个表型性状为基本数据,依据舌状花花色分为8组,采用系统聚类法进行聚类分析。基于2种遗传距离、4种聚类方法和5种总体取样规模构建了40个候选切花小菊核心种质,并利用4个评价指标比较构建效果。利用筛选得到的最佳构建方案构建初级核心种质。以6个特征值和5个评价参数综合评价所构建核心种质,以检验核心种质有效性和代表性。结果表明,采用标准化欧氏距离、离差平方和法、10%总体取样比例的备选核心种质综合表现最佳。最终构建获得包含95个切花小菊品种的初级核心种质,占原种质10%。核心种质评价表明初级核心种质构建有效且质量较高,能够在保证冗余较少的情况下充分代表原种质遗传多样性。

Based on the 13 morphological traits of 950 accessions of spray cut chrysanthemum (Chrysanthemum morifolium)including eight ligulate flower color groups preserved by China Chrysanthemum Germplasm Resources Conservation Center,cluster analysis was performed by systematic cluster method. Based on two genetic distances,four clustering methods and five overall sampling scales,40 candidate core collections were constructed,and thereafter four evaluation indexes were used to compare the quality of the candidate core collections and an optimal scheme was selected to construct primary core collection. Six characteristic values and five evaluation parameters were used to comprehensively evaluate the effectiveness and representativeness of core collections,and finally an optimum core collection constructed by standardized Euclidean distance,Ward's method and 10% overall sampling ratio was observed showing superior comprehensive performance. The derived primary core collection containing 95 spray cut chrysanthemums could fully represent the genetic diversity of the original collection under the condition of less redundancy,and thus should be effective and of high quality.

Key words: chrysanthemum, cut flower, core collection, morphological trait, construction strategy
