蜡梅品种分类研究

在对栽培蜡梅品种系统调查的基础上,对蜡梅品种资源进行了初步分类研究。在前人研究的基础上,结合实地调查的结果,分析了蜡梅品种的主要形态特征和分类依据。遵循《国际栽培植物命名法规》与品种演化规律,同时考虑到实际应用,确定蜡梅品种分类的依据,制定蜡梅品种分类的三级标准。按照花色将蜡梅品种分为3个品种群:蜡梅品种群、白花蜡梅品种群和绿花蜡梅品种群。认为花色、内被片颜色、花型、花径大小及花期是蜡梅品种分类的主要依据,而叶片特征、果实形状、株型及枝条特征仅作为辅助依据。同时提出,进行蜡梅品种识别应抓住典型的、较为稳定的性状以及某些品种特有的个性,而非典型、不稳定的性状不应该作为品种区分的依据。

Cultivar classification of wintersweet

Based on an overall investigation of cultivar resources of the wintersweet (Chimonanthus praecox),we recorded the existing cultivars and presented preliminary cultivar classification.Based on previous work of other researchers and our field survey data,we analyzed main morphological characteristics and cultivar classification principles.In the light of International Horticulture Nomination Code and the regulation of cultivars evaluation,practical application was also taken into account.The cultivar classification principles and three-grade criteria were presented.The cultivar groups and cultivar systems were built up.According to the flower color,cultivars were divided into three cultivar groups,which are Praecox group,Albus group and Viridiflorus group.Flower color,inner flower color,flower size and type as well as flowering period were taken as the main considerations,and the characteristics of the leaf,shape of the fruit,plant appearance and the branch feature could be taken as auxiliary judgments.We suggest that,for the identification of cultivars,typical,stable traits and unique characteristics of some cultivars,instead of those atypical and unstable characteristics,should be focused on.
