STORAGE LIFE AND QUALITY OF F1 HYBRID TOMATOES WITH NON RIPENING GENE.
Fruits of F1 hybrids carrying the nor characteristic required a longer period from harvest to reach the breaker stage and ripened slowly between the breaker and table ripe stages. Only one hybrids (L276xnor) had an extended shelf life at 20°C after reaching the table ripe stage. Percent of ripened fruits during storage was much higher for standard cultivar compared to the nor hybrids. The visual quality of tomato fruits at table ripe stage was similar at both storage temperatures, except for one hybrid L276xnor which had the lowest scores.
Vitamin C levels generally decreased during ripening of tomato fruits, but small differences in vitamin C content were observed, between cultivars and storage temperatures.
There were not significant differences among studied cultivars in total sugar levels after 1 or 2 months of storage at two temperatures but a tendency of decreasing sugar content during ripening was observed.
The results suggest that almost all F1 nor hybrids studied had a silimar storage life like the standard cultivar.
