摘要
为了给油茶的栽培和良种繁育提供科学依据,在福建省福安市优选的12个油茶家系栽培试验的基础上,对试验调查结果进行综合分析和等级划分。在对油茶家系多性状的灰色理论关联度分析和聚类分析的基础上,对油茶家系进行分类,将12个油茶家系分成3个等级。其中优等家系2个,性状好、年产油量高;中等家系3个,性状稳定、年产油量较高;普通家系7个,性状不稳定。
In order to provide scientific basis for cultivation and propagation of improved varieties, 12 superior families in Fu＇an City were classified by grey relational degree analysis and cluster analysis, based on cultivation experiment. Twelve superior families were classified into 3 clusters. Two families were in the finest cluster with good characters and high annual oil yield; three ones were in the middle cluster with stable characters and high yield; seven ones were in the common cluster with unstable characters.
