Abstract: The performance of eight tomato hybrids was studied under plastic tunnel for number of days to flowering and maturity, number and weight of fruit per plant, single fruit weight and yield. The sequential pickings in tomato hybrids started in second week of December 1991 and finished in the last week of March 1992. The cultivars parana and turquesa matured earlier taking 95.25 and 98.75 days, respectively. The cultivar turquesa with maximum fruit weight plant-1 exhibited the highest yield of 20.45 kg m-2 followed by fortara, royesta and jacinto yielding 19.55, 18.92 and 18.30 kg m-2, respectively.
