New tomato hybrids with long shelf life

Abstract

Slow ripening and long shelf life of tomato fruits are traits controlled by several ripening inhibitor genes (nor - non-ripening, nr - never ripe, rin - ripening inhibitor, ale - alcobaca). In our tomato breeding programs, the best results had the combination of rin/rin(+) genotype. Fruits of these genotypes ripen slowly, have a shelf life of 2-3 weeks and at the same time have relatively good color, firmness and taste. The results are tomato hybrids Nada F-1 and Sampion F-1. Hybrid Nada F-1 is indeterminate, with large habitus and a good amount of foliage. Fruits are very firm, round to flattened globe, smooth, without the green shoulder and average weight is 200-220 g. Unripe fruits are dark green, while ripened fruits are deep red. This hybrid is resistant to Verticillitan albo-atrum, Fusarium oxysporum f. sp. lycopersici and Meloidogyne spp. Hybrid Sampion F-1 is indeterminate, with medium habitat and a good amount of foliage. Fruits are very firm, round and smooth, without the green shoulder and ribs, and average weight is 180-200 g. Unripe fruits are light green, while ripened fruits are deep red. This hybrid is resistant to Verticillium albo-atrum, Fusarium oxysporum f. sp. lycopersici and Meloidogyne spp.
