摘要
为了预测单株产油量及茶油品质等质量性状,给油茶良种选育提供参考,通过对油茶优树各性状的调查,应用典范相关分析法研究油茶生物学性状与质量性状之间关系。结果表明,单果籽质量和单果质量为第一典范变量因子中的主导因子,与质量性状中油酸含量、亚油酸含量、单株产油量之间的关系密切,典范相关系数0.949 4,达到显著水平;由第一对典范相关构造成一个综合选择指数方程,对20株油茶优良单株进行综合评定,并将其分成3类。该方法可揭示油茶性状间的关联性。
In order to predict quality properties, such as yield and quality of tea oil, and provide a reference for breeding improved variety in Camellia oleifera, some characters of the fine trees were investigated, the relationship between biological and quality characters was studied by canonical correlation analysis. The results show that seed mass per fruit and single fruit mass are the leading factors among the first canonical variables, which are significantly related to oleic acid content, linoleic acid content and oil production of single plant, and canonical correlation coefficient is 0.949 4, it reach a significant level. A comprehensive selection index equation was established by the first pair of canonical correlation, 20 fine trees were evaluated comprehensively and divided into three categories. This method can preliminarily reveal the relationship between characters in C. oleifera.
