Characterization of a collection of local varieties of tomato (Solanum lycopersicum L.) using conventional descriptors and the high-throughput phenomics tool Tomato Analyzer

摘要: Conventional tomato (Solanum lycopersicum L.) descriptors are of great utility for gross morphological characterization but may not be practical the precise fruit description required distinguishing closely related cultivar groups. Tomato Analyzer is a new phenomics tool that provides multiple morphology data from scanned images sections. We characterized 69 accessions local varieties region Valencia (Spain) corresponding to eight groups (Borseta, Cherry, Cor, Penjar, Plana, Pruna, Redona, and Valenciana) with 64 conventional 38 descriptors. Significant differences were found among all traits except five monomorphic descriptors, revealing large diversity in collection. also 36 37 The Borseta, Pruna clearly distinct each them presented many significant rest did differentiate well Valenciana groups, distinguish Cor Redona A multivariate principal components analysis (PCA) showed exception six (8.7 %) accessions, different (including very similar Redona) plotted separate areas PCA graph. results have shown combined conjunction powerful classification varieties, as between This has important implications enhancement protection varieties.
