This experiment was performed to obtain the basic information on heterosis and heterobeltiosis of quantitative characters in the eggplant by crossing of varieties. The heterosis and heterobeltiosis were estimated in F1 generation. The results were as follows, based on the graphical analysis, the characters, plant height, stem diameter, fruit weight, leaf length, leaf width, and fruit number per plant(yield) were assumed to inherit dominance, and fruit length and fruit diameter were found to inherit incomplete dominance. The degree of positive heterosis of plant height, stem diameter, fruit weight, fruit length, fruit diameter, leaf length, leaf width, and fruit diameter, leaf width, leaf length, fruit weight, and stem diameter showed negative heterobeltiosis.
