ResumoThe objective was to estimate the combining ability of lines and heterosis in industrial tomato genotypes for the identification of those with good potential for breeding programs. Ten lines of industrial tomato, 45 hybrids derived from a complete diallel and two commercial check cultivars were evaluated. The combining ability of tomato lines and heterosis of hybrid combinations for fruit-quality related traits were estimated. Non-additive effects predominated in the genetic control of all traits. The parent lines RVTD-04, RVTD-10 and RVTD-08 had an exceptionally high presence of favorable alleles for most traits. High genetic divergence between the parents was observed, contributing positively to significant heterosis values. The above lines can be used in breeding programs to develop tomato hybrids with high performance for characteristics related to industrial processing.
