Morphological, physiological, fruit yield and quality related traits were compared between the seed-grown and tissue-cultured plants of tomato (Lycopersicon esculentum Mill.) cv. Red Coat in a greenhouse. No significant differences were observed for any of the traits studied except for the number of leaves and branches, which were higher in the seed-grown plants than in tissue-cultured plants at the later stages of growth. No phenotypic abnormality of the tissue-cultured plants was observed suggesting that genetic fidelity of tissue cultured plants can be maintained if appropriate plant growth regulators are used with fewer member of subcultures in the multiplication medium.
