摘要:

通过对加工番茄品种多性状进行综合评价,为鉴定、筛选其优良种质资源提供决策支持。选取9个加工番茄品种(系)进行品比试验,分析、测定其13项农艺性状,并联合使用主成分分析和聚类分析法(PCA -CA),对加工番茄主要农艺性状进行综合分析。13项农艺性状的平均变异系数为10.23%。运用主成分分析法,可将13项农艺性状归纳为果实外观品质因子、果实产量因子和果实内在品质因子3个主要指标,3个主要指标可较准确地评价加工番茄品种。其中,株高、单果重、果实纵径、果实横径、平均产量、可溶性固形物、番茄红素、总酸8个性状是主要性状。综合得分排名前2位的依次是‘T60’、‘新番15号’。采用类平均法对9个加工番茄品种进行系统聚类分析,将所有番茄品种分为5个类群。本研究建立的加工番茄综合评价体系可为加工番茄优质品种的选育提供参考依据。

Abstract:

Through comprehensive evaluation of multiple traits of processing tomato varieties, the study aims to provide technical support for identification and screening of excellent germplasm resources. 9 processing tomato varieties (lines) were selected for variety comparison test, and 13 agronomic traits were analyzed and determined. The principal component analysis and cluster analysis (PCA-CA) were used to conduct a comprehensive analysis of the main agronomic traits of processing tomato varieties. The average coefficient of variation of 13 agronomic traits was 10.23%. By principal component analysis, 13 agronomic traits could be divided into 3 main indexes: fruit appearance quality factor, fruit yield factor and fruit intrinsic quality factor, which could accurately evaluate processing tomato varieties. Plant height, weight of single fruit, longitudinal diameter, transverse diameter, average yield, soluble solid content, lycopene content and total acid content were the main traits. ‘T60’ and ‘Xinfan 15’ ranked the first and second on comprehensive scores. Cluster analysis of the 9 processing tomato varieties was carried out by group-average method, and the varieties could be divided into 5 groups. The comprehensive evaluation system established in this study can provide reference for breeding high-quality processing tomato varieties.

Key words: processing tomato, varieties (lines), agronomic traits, principal analysis, cluster analysis, evaluation index
