摘要:

本研究对151份贵州地方樱桃番茄资源农艺性状(13个质量性状和11个数量性状)进行变异水平评价、遗传多样性分析、主成分分析及聚类分析。结果表明:质量性状的遗传多样性指数整体低于数量性状;质量性状中叶片颜色Shannon-Wiener多样性指数最高,数量性状中最高的是果实纵径,心室数的变异系数最大(32.47%)。不同的性状之间的关系复杂,前7个主成分花序类型、单花序果数、果柄长度、果实纵径、果实横径、单果质量、叶宽的累计贡献率67.633%,包含了全部指标的大部分信息。基于表型性状,采用系统聚类组间聚合方法在遗传距离为3.0处将151份资源划分为9个类群,第1类群包含36份资源,主要特点为果实圆形,熟性为早熟和极早熟;第8类群中编号30和76的两个材料植株生长力强,表现优异;第9类群包含17份资源,其主要特征是单果质量小,熟性为中熟和晚熟为主。

Abstract:

In this study, agronomic traits (13 quality traits and 11 quantitative traits) of 151 local cherry tomato resources in Guizhou were evaluated by variation level, genetic diversity, principal component analysis and cluster analysis. The results showed that genetic diversity index of the quality traits was lower than quantitative traits, among the quality traits, Shannon-Wiener diversity index of leaf color was the highest.The highest quantitative trait was the longitudinal diameter of the fruit, the coefficient of variation of ventricular number was the highest (32.47%). The relationships between different traits were complex, the accumulative contribution rate of the first 7 main inflorescence types, fruit number of single inflorescence, stalk length, fruit longitudinal diameter, fruit transverse diameter, fruit mass and leaf width was 67.633%, which included most of the information of all indexes. Based on phenotypic traits, 151 resources were divided into 9 groups at a genetic distance of 3.0 by systematic cluster intergroup polymerization. The first group contained 36 resources, which were mainly characterized by round fruit, early ripening and very early ripening. In group 8, No. 30 and No. 76 had strong growth ability and excellent performance; group 9 contained 17 resources, which were characterized by low single fruit weight and medium and late maturity.

Key words: cherry tomato, agronomic traits, genetic diversity analysis, principal component analysis, cluster analysis
