【摘要】 分析了34个广西龙眼品种(单株)的8个主要果实性状间、性状与品种的关系,并进行品种综合评价与分类。在相关分析基础上进行因子分析,结果表明,8个性状分别载荷在5个主因子上,第一主因子为果实综合因子,包括单果重、果肉厚度、可食率和可溶性固形物含量;第二至五主因子分别为反映果实质地、成熟期、果核重、风味的因子,这5个主因子对8个性状的累计方差贡献率达到93.329%,基本概括了全体8个性状的主要信息。模糊综合评价和两阶段聚类分析结果显示,桂明1号、中圆、细核脆香、石硖、国庆1号、桂香、良庆1号、良庆2号、桂圆0503等品种综合性状最佳,并根据因子分值分成四个类别,可为龙眼品种(单株)的应用、亲本选配提供理论依据。

【Abstract】 The relationships between characters and varieties,and the relationships among 8 main characters of 34 Longan varieties in Guangxi were analyzed.At the same time,comprehensive assessment and classification of varieties were done.The result showed that 8 characters were loaded on 5 main factors.The first were intergrated factor of fruit,including single fruit weight,pulp thickness,edible rate and contents of soluble solid state material,From the second to the fifth factors,it reflected the fruit texture,mature period,fruit pit weight and flavor,respectively.The accumulation variance of five main factors contributing to the 8 characters reached to 93.329 %,which basically summarized all 8 characters main information.The results of fuzzy intergrated evaluation and two stage cluster analysis showed that the comprehensive characters of Guiming No.1,Zhongyuan,Xihecuixiang,Shixia,Guoqing No.1,Guixiang,Liangqing No.1,Liangqing No.2 and Guiyuan 0503 were better than others.It was divided into four categories according to factor scoring,and it will provide the theory basis for the longan variety application and parent select.
