Abstract: Density of certain types of trichomes (Type I,IV and VI) and the length of type I and IV trichomes were characterized on cotyledonary leaves and hypocotyl and root characters line length of primary root and number of secondary and tertiary roots was recorded in seedling stage in tomato to differentiate the tomato hybrids from their parental lines. Variation for Type VI trichomes was found to be significant for hybrids PH-1, PH-4 and PH-8 from one or both of their parental lines. Type I trichomes were present in only four out of ten genotypes under study viz., PH-1, PH-4, Female-1 and Male-1. For root traits also, significant differences were found among the hybrids and their parental lines. For all the traits tested, the hybrids were found to be depart significantly from one or both of its parental lines with the characters studied.
