dc.description.abstractTomato germplasm is source of variability used by plant breeders to develop improved cultivars and part of the natural heritage to be preserved. In this study, the diversity among twenty Portuguese tomato accessions was evaluated, considering morphological and agronomic descriptors, molecular data, and compositional aspects. The tomato accessions captured 77.5% of the total 19 alleles detected. Important information on the selection of SSR loci in diversity analysis for the tomato genotypes was provided. The studied genotypes were rich in car-bohydrates and source of ascorbic acid. Citric acid and palmitic, linoleic, oleic, stearic, and alpha-linolenic acids were the major organic and fatty acids, respectively. The four tocopherol isoforms were detected and alpha-tocopherol was the most abundant. When correlating molecular and compositional data, it seemed that the greater the het-erozygosity, the greater the compositional variance. However, despite the genetic distance that characterized these accessions, some were chemically similar. Overall, the genetic differentiation among genotypes provided useful information for parental selection in breeding and other genetic studies.pt_PT
