Resumo: | ABSTRACT Tomato crop presents several obstacles that hinder its cultivation, especially the tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae). To reduce damages caused by this pest, the development of resistant cultivars is one of the main alternatives. In this study we aimed to select tomato genotypes with high acylsugar contents and resistant to tomato leafminer. For this, contrasting F2RC1 genotypes for allelochemical contents, resulting from the interspecific cross between cultivar Redenção with processing characteristics, and the wild species Solanum pennellii accession ‘LA-716’, with high acylsugar contents, were submitted to a test of resistance to tomato leafminer with 14 treatments, being eight genotypes with high acylsugar content and four with low acylsugar content, in addition to the parental. Significant correlations and contrasts were observed between acylsugar contents and traits related to the resistance to tomato leafminer. The genotype RVTA-2010-31-pl#177 presented similar behavior to the wild parental, demonstrating potential to advance in the tomato breeding program for industrial processing with resistance to tomato leafminer.
