Control genético del carácter número de frutos por planta y sus componentes en un cruzamiento dialélico entre cultivares de tomate "chonto", Lycopersicon esculentum Mill
Genetic analysis for fruits per plant, clusters per plant and fruits per cluster characters was carried out using a diallel crossing between seven "chonto" tomato cultivars (Angela Gigante, Licapal- 21, Raminho, Olho Roxo, 1258, 1465 and 1507). Was made a genetic- statistic analysis using the methodology developed by Hayman (1954 a, 1954b). There was no evidence of epistasis in any of characters studied and the experimental data are adjusted to the additive-dominant model. Additive gene action and non-additive gene action participate jointly and highly significant manner, in the fruits per plant, and clusters per plant characters expression. Fruits per cluster character is conditioned mainly by the non-additive gene action. It is detected the presence of sobredominance in three studied characters. It's could estimate selection lirnits to the fruits per plant (34.12 and 3.15) and to the fruits per cluster (4.37 and 0.29). For cluster per plant character, it was not possible to estimate them because of low correlation showed between dominance degree and mean value of character.
