Abstract: The Inter-Simple Sequence Repeat marker technique was applied to a set of tomato genotypes that were found to diverge in antioxidant compounds in fruits. As marker-assisted selection is becoming a tool that brings major advantages for breeding programs need is rising to use it to quickly respond to consumer demand. Being part of a system for efficient plant breeding in many crops the aim of the present study was to test Inter-Simple Sequence Repeats as candidate tool for incorporating in a breeding program aiming to improve antioxidant properties of tomato fruits. Application of Inter-Simple Sequence Repeat markers resulted in obtaining adequate representation of every accession from the selected group. This opens the opportunity for using the system in confirming the hybrid nature of the F1 progenies and further accelerating the breeding of genotypes for use as healthy food.
