摘　　要：根据2001年至2003年的田间调查,从北京和天津引种的12 000株“耐冬”山茶中筛选出抗冻优良单株56株。此外,对青岛植物园“耐冬”山茶55个性状的R型聚类分析结果表明,部分营养器官性状与生殖器官性状具一定相关性。根据这些相关性,对筛选出的部分优良单株的花色和花型进行了预测。“Naidong” camellia is a geographic population of Camellia japonica distributed in Qingdao area of Shandong Province. Among all camellias in China, “Naidong” camellia is the northernmost distributed camellia. In order to enrich the landscape color and improve the enviromental quality, “Naidong” camellia were introduced from Qindao area to Beijing and Tianjin areas, and the freezing resistant individuals among them were selected out. In addition, the flower characters of some individuals were predicted. After two full winter investegation, 56 freezing resistant individuals from more than 10 thousand seedlings were selected out. The results of R cluster analysis showed that some characters of “Naidong” camellia are related to other characters. On the basic of this relativity, the flower colors and flower types of 10 freezing resistant individuals were predicted. As a result, the breeding period would be shortened, and the application and dissemination would be put forward.
