Randomized complete block design was used, with three replications. Heterosis for yield and fruit quality characteristics was studied, and expressed as Relative heterosis, heterobeltiosis and Standard heterosis. It would be expected, according to the dominance model, that the heterosis recorded after crossing the recombinant lines, having only a small portion of recessive deleterious alleles, would be minimal. The results showed that the elite recombinant inbred lines became the parents of elite restructured hybrids, with increased levels of re-heterosis for all characters measured. This may prove that dominance is not the only case in explaining heterosis in tomato for yield components and fruit quality characteristics. Several recombinant lines, and most of the new reconstructed F1 hybrids, showed excellent productivity under a low input farming system. The evaluation and selection of the different types of cultivars (recombinant pure lines or reconstructed hybrids) under low input conditions could point towards the most suitable/ideal genotype for organic cultivation.
