摘要
该文简单概述了蜡梅品种分类的历史 ,分析了蜡梅花器官主要性状中的遗传变异 ,综合各种因素确立了蜡梅品种分类的标准与等级 ,即以种型作为品种分类的第一级分类标准 ,以花的大小及花内被片紫红色斑纹状况分别作为第二、三级分类标准。最后提出了一个以种型为基础的系、以花大小为标准而划分的类、以花内被片紫红色斑纹状况为基础划分的型组成的一个三级品种分类体系。
The plants of Chimonanthus were cultivated as garden plants in China for over 1 000 years. But the classification system of cultivars has not been best solved and some confusions of cultivar classification still existed in Chimonanthus. In this paper the history of cultivar classification was briefly reviewed. Then genetic variability of the main morphological traits in flowers of Chimonanthus was analyzed. Based on these factors the criterion and its rank of classification were defined: namely the types of species as the first rank of classification criterion formed the Branches of cultivars, the sizes of flower and the purple streaks or patches of inner_petals were respectively taken as the second and third rank of classification criterion, and the cultivars with different sizes of flowers were classified into different Groups and in each Group the cultivars with the different purple streaks or patches of inner-petals were put into different Forms. Thus the Branches, Groups and Forms composed a classification system of cultivars in Chimonanthus.
