Thirty six tomato genotypes, including cultivar, were evaluated at National Agricultural Research Centre, Islamabad, during summer, 2002 and 2003 to estimate the nature and magnitude of genetic variability based on days to first harvest, number of pickings, plant height, number of fruit per plant, fruit weight per plant, fruit size, single fruit weight, number of locals, pericarp thickness, TSS, fruit pH, seeds per fruit and 1000 seed weight. A wide range of variation was observed among the characters studied, which have a great interest for tomato breeders. Heritability for (broad sense) ranged from 51.8 to 99.8 % in 2002 and from 86.0 to 99.9 % in 2003. Single fruit weight gave the highest heritability during 2002, however, it was at maximum for days to first harvest during 2003.
