Three garden egg (Solanum gilo) cultivars: Tinguá, Comprido Verde Claro, and Morro Redondo were crossed in a diallel scheme including reciprocals. Parental cultivars and F1 hybrids were evaluated under field conditions in relation to 14 agronomic traits. Seven of these traits were statistically analysed and significant effects of general combining ability demonstrated for fruit length, fruit diameter, mean fruit weight, number of days from planting to initial harvesting, and plant height. With respect to specific combining ability there was significance for all characteristics analysed, showing that dominant/epistatic effects were involved in their genetic control. The hybrids: 'Tinguá´ x 'Comprido Verde Claro´ and 'Comprido Verde Claro´ x 'Morro Redondo´ showed promising results for fruit yield.
