| 为推进广宁红花油茶 Camellia semiserrata 的选育工作, 以广宁县初选广宁红花油茶优株为研究
材料, 采用方差分析、 多重比较、 相关性分析和聚类分析方法, 开展植株生长和果实性状遗传变异特征
分析与评价。 结果表明, 初选的 169 株广宁红花油茶生长和果实性状存在不同程度的变异, 变异系数为
23. 57% ~97. 30%; 不同乡镇间的广宁红花油茶果实性状具有极显著差异 (P<0. 01); 广宁红花油茶果实
性状间的相关系数均达到了极显著水平 (P<0. 01), 单果质量与果实横径、 纵径、 果皮厚、 鲜籽质量均具
有极显著正相关性 (P<0. 01)。 基于 11 个果实性状, 对 30 株广宁红花油茶优树进行聚类分析, 最终将其
划分为 4 个类型, 第 I 类属于小果类型, 鲜出籽率、 干出籽率和果实含油率高于其他类; 第Ⅱ和Ⅳ类属于
中果类型; 第Ⅲ类属于大果类型, 单果质量、 果实纵径、 果实横径指标均高于其他类。 广宁县的广宁红
花油茶生长和果实性状具有较丰富的变异。 |

| Abstract: |
| To advance the breeding program of Camellia semiserrata, this study utilized superior individual
trees initially selected from Guangning county as experimental materials. Analysis of variance (ANOVA), multiple comparisons, correlation analysis, and cluster analysis were employed to conduct analysis and evaluation of
genetic variation characteristics in growth and fruit traits of C. semiserrata. The results show that there were rich
variations in the growth and fruit traits of 169 excellent trees selected of C. semiserrata, and the coefficient of
variation was 23. 57%-97. 30%. There were significant differences in fruit traits among different towns. The
correlation coefficients between fruit traits reached a very significant level (P<0. 01). Single fruit fresh weight had a significant positive correlation with fruit height, fruit diameter, pericarp thickness and fresh seed weight
per fruit. Based on 11 fruit traits, 30 superior trees of C. semiserrata were divided into 4 groups by cluster
analysis. Among them, the first group belonged to the small fruit type, and fresh seeds ratio, dry seeds ratio,
fruit oil content were higher than other groups. Groups Ⅱ and Ⅳ belong to midium fruit type. Group Ⅲ belongs to the large fruit type, and the single fruit weight, fruit height, and fruit diameter were higher than other groups. The growth and fruit traits of C. semiserrata in different towns of Guangning county have rich variability. |
