36个油茶优良单株综合评价及主要性状分类

Study on Compenhensive Evaluation of 36 Superior Individuals and Classification of the Main Characteristics

摘要:

摘要：本文采用相关分析法和主成分分析法及因子负荷量图，对36个优良单株的8个主要性状进行相关分析、综合评价及性状分类。结果表明：①3年平均冠幅产量与干出籽率存在极显著的负相关关系，果形指数与鲜出籽率存在显著的负相关关系，鲜出籽率与干出籽率存在显著的正相关关系；②筛选出综合性状表现更好的前10个，分别是：qc7、qc1、mc1、ha6、ha1、qc10、mc12、qc9、ha2、mc2；③将8个主要性状分为3类，分别为出籽率因子、产量因子和果实因子。

Abstract:

Abstracts:Using the relative analysis method, the principle component analysis method and load factor diagram, we analyzed the correlation of the eight main characteristics of 36 superior individuals, evaluated comprehensively them, and at last classified their eight main characteristics. The results showed that ①It was significantly negative correlation between average crown yield of 3 years and dry kernel ratio, and between fresh kernel ratio and fruit index, and it was significantly positive correlation between fresh kernel ration and dry kernel ratio; ②The 10 superior individuals of the better comprehensive characteristics were selected, which were qc7,qc1,mc11,ha6,ha1,qc10,mc12,qc9,ha2,mc2; ③The eight main characteristics were classified as 3 classes which were kernel ratio factor, yield factor and fruit factor.
