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.

Se realizó el análisis genético del carácter número de frutos por planta y sus componentes utilizando un cruzamiento dialélico entre siete cultivares de tomate "chonto" (Ángela Gigante, Licapal- 21, Raminho, Olho Roxo, 1258, 1465, y 1507). El análisis genético-estadístico se efectuó utilizando la metodología desarrollada por Hayman (1954 a, 1954b). No se detectó evidencia de epistasis para ninguno de los caracteres estudiados y los datos experimentales se ajustaron al modelo aditivo-dominante. La acción génica aditiva y no aditiva participaron en forma conjunta y significativa en la expresión de los caracteres número de frutos por planta y número de inflorescencias por planta. Solamente la acción génica no aditiva participó en forma significativa en la expresión del carácter número de frutos por inflorescencia. Se detectó la presencia de sobredominacia en los tres caracteres estudiados. Se pudieron estimar los límites de selección para el carácter número de frutos por planta (34.12 y 3.15) y para el carácter número de frutos por inflorescencia (4.37 y 0.29) para padres completamente dominantes y recesivos, respectivamente. Para el carácter número de inflorescencias por planta, no fue posible estimarlos debido a la baja correlación presentada entre el grado de dominacia y el valor medio de los progenitores.
