Seven cultivars of tomato (Lycopersicon esculeutum Mill.) were planted at 2 locations and 2 seasons to obtain estimates of their genotypic and environmental variability. pH, titratable acidity, reducing sugars, total soluble solids and pulp colour were affected by season, while the titratable acidity and colour were also affected by location. All cultivars were found suitable for processing with regard to pH, but the other characteristics varied with cultivar, some being below standards for processing in some cultivars. The characteristics were heritable to an appreciable degree, indicating that a new adapted cultivar may be developed.
