摘要:

对世界山茶属(Camellia)植物品种注册中心2021年及以前已登录的滇山茶(C. reticulata)823个品种进行资源和形态特征分析,并对其中形态特征记载完整的213个品种进行性状多样性分析、主成分分析和聚类分析。结果表明:滇山茶品种资源丰富,中国、美国和澳大利亚是主要来源地;其花色以红色系为主,其次是粉色,稀有复色和白色;花型主要为半重瓣型和重瓣型,少有单瓣型;叶形以椭圆形为主,其次为圆形、卵形、披针形;叶尖以渐尖为主,叶基以楔形为主。213个品种的表型多样性指数(H)为0.41 ~ 1.91,其中叶宽的H值最大(1.91);变异系数(CV)为15.16% ~ 49.08%,叶长的CV最小(15.16%),花瓣数的CV最大(49.08%);通过主成分分析,推测叶片的性状对滇山茶品种分类有重要作用;以叶片大小、花瓣数等聚类,213个品种可分为3个类群,第Ⅰ类群可作为单瓣型花良种选育的材料,第Ⅲ类群花瓣数和叶片较大,可作为重瓣型花良种选育的材料。

Abstract:

Based on the World Camellia Plant Variety Registry,823 cultivars of Camellia reticulata that had been registered in 2021 and before were analyzed for the resources and biological characteristics,and traits diversity analysis,principal component analysis and cluster analysis were carried out for 213 cultivars whose morphological characteristics were well documented. The results showed that Camellia reticulata cultivars are rich in resources,and China,the United States and Australia are the main sources of their cultivars. The flower color is mainly red,followed by pink,rare compound color and white. The flower types are mainly semi-double petals and double petals,and there are few single-petal groups. The leaf shape is mainly elliptic,followed by round,ovate and lanceolate. The leaf tip is mainly tapering,and the leaf base is mainly wedge-shaped. The phenotypic diversity index(H)of 213 cultivars was 0.41-1.91,among which the H value of leaf width was the largest(1.91). The coefficient of variation(CV)was 15.16%-49.08%,among which the leaf length was the smallest(15.16%)and the largest number of petals(49.08%). Through principal component analysis,it was shown that the characteristics of leaves played an important role in the classification of Camellia reticulata cultivars. Clustered by leaf size and number of petals,the 213 cultivars can be divided into three groups. GroupⅠcan be used as breeding materials for single-petal flower breeding,and group Ⅲ has a large number of petals and leaves,which can be used as breeding materials for the selection and breeding of double-petal flower cultivars.
