Mineral and trace elements content in 30 accessions of tomato fruits (Solanum lycopersicum L.,) and wild relatives (Solanum pimpinellifolium L., Solanum cheesmaniae L. Riley, and Solanum habrochaites S. Knapp & D.M. Spooner).

Tomato quality and its potential health benefits are directly related to its chemical composition. The characterization of nutritional properties of Solanum germplasm is essential to choose suitable donor parents for breeding programs. In this sense, wild species could be very useful for tomato fruit quality genetic improvement. With this objective, in this work, we characterize micronutrients content in Eulycopersicon germplasm (20 cultivars of S. lycopersicum L. and 10 accessions of wild relatives) analyzing mineral (Na, K, Ca, Mg) and trace elements (Cu, Fe, Zn, Mn) and applying multidimensional analysis (principal component and cluster analysis). The classification obtained and the comparison of cultivars performance showed that wild accessions belonging to S. cheesmaniae (L. Riley), S. pimpinellifolium L., and S. habrochaites S. Knapp & D.M. Spooner can be of great usefulness in breeding programs to improve mineral content characteristics of conventional S. lycopersicum varieties due to its higher mineral content.
