The eggplant, because of its positive effects on human health, is a vegetable with prospective domestic and international markets. In Colombia the crop presents technological limitations, lacking improved cultivars for the tropical conditions. This study was conducted at the University of Cordoba, Montería, with the aim of identifying the optimal flower bud development for artificial hybridization, which should lead to the formation of fruit and seed production. Cultivars Brinjal Super Mohini (hypocotyl green and white fruit) and Taiwan (hypocotyl and purple fruit) were used as female and male parents, respectively. A complete randomized block design with eight treatments and four replications was employed. The treatments consisted in the combination of various stages of flower development; as female part: cream coloured flower bud corolla (pre-anthesis), clear purple coloured flower bud corolla (near anthesis) and purple coloured flower bud corolla (beginning anthesis); as male part: corolla of the flower bud slightly purple coloured (near anthesis), purple coloured (beginning anthesis) and the fully open flower at 8:00 am. With creamy flower buds (pre-anthesis) no success in artificial hybridization was obtained, while with the combinations of slightly purple buds (pre-anthesis), purple buds (beginning anthesis) and fully open flower the hybridization was effective, but without significant differences between the successful combinations tested. The same statistical result was obtained for fruit weight, number of seeds per fruit and seed index.

Keywords : vegetable; flower bud; anthesis; fruit weight; seed index.
