Characterization of composition traits related to organoleptic and functional quality for the differentiation, selection and enhancement of local varieties of tomato from different cultivar groups
[EN] Tomato (Solanum lycopersicum) local varieties are having an increasing demand. We characterized 69
local tomato accessions from eight cultivar groups for proximate composition traits, major sugars, acids
and antioxidants. A large diversity was found, with differences among accessions of almost tenfold for
lycopene. Significant differences were found among cultivar group means for most traits. The Cherry
and Penjar groups generally presented higher dry matter, soluble solids content, titratable acidity, taste
index, b-carotene, ascorbic acid, total phenolics, and antioxidant activity that the other groups. Wide
ranges of variation were found within each cultivar group. Positive correlations were found between
proximate traits related to taste and antioxidants. The multivariate principal components analysis con-
firms the distinct profile of the Cherry and Penjar groups and the large variation within groups. The
results will be useful for the differentiation, enhancement and selection of local tomato varieties with
improved organoleptic properties and functional quality.
