油茶经济性状通径分析和聚类分析研究

Study on Economic Characters of Tea-oil Trees by Path Coefficient Analysis and Cluster Analysis

本文连续3年对3片试验林74个油茶无性系经济性状进行测定,采用通径分析和聚类分析方法,探讨油茶经济性状的相互关系和类型划分。结果表明,干籽率对果含油率的直接效应最大,红桃、红球、黄桃、黄球等果实类型含油率较高,青桃、青球等果实类型含油率较低。

The experiments of measuring the economic characters of 74 clones in 3 test sites of tea-oil trees had been carried out in successive 3 years. Relationship and classification of economic characters were discussed by path coefficient analysis and cluster analysis. The results shoved : ( 1 ) Rate of dry-seed has the most direct effect on the oil content of fruit-, (2) fruit types as red-peach, red-ball, yellow-peach, yellow-ball, etc. have more oil content and fruit types of green peach, green ball, etc. have less oil content.
