Six lines (Morro Redondo, Branco Comprido, BGH-1544, Tinguá, Irajá, Comprido Verde Claro) and 15 hybrids resulting from a diallel cross among them (reciprocals excluded) were tested in a randomized complete block design with four replications.

Heterosis for mean fruit mass was associated with incompletely dominant gene action, and larger fruit mass was associated with larger proportions of dominant alleles.

Los objetivos de este trabajo fueron evaluar la heterosis y sus componentes en los híbridos F1 de una dialélico entre líneas de jiló (Solanum gilo Raddi, syn. S. aethiopicum L.), y el estudio de los modos de acción de los genes asociados con su expresión. Seis líneas (Morro Redondo, Branco Comprido, BGH-1544, Tinguá, Irajá, Comprido Verde Claro) y 15 híbridos resultantes de un cruce dialélico entre ellos (recíprocos excluídos) se pusieron a prueba en un diseño de bloques completamente aleatorio con cuatro repeticiones. Los rasgos estudiados fueron producción total, peso promedio del fruto y la relación longitud/diámetro. No hubo evidencia de la acción de genes epistatic en la expresión de cualquiera de los rasgos en estudio. Para la producción total, la heterosis se explica por la acción de genes overdominance, ya que había una asociación débil, no significativa, entre los alelos dominantes y los valores de producción de frutas altas totales. La heterosis de masa media de la fruta se asoció con la acción del gen dominante incompleto, y la masa da fruta más grande se asoció con una mayor proporción de alelos dominantes. Para la relación longitud/diámetro (LD-1), la heterosis fue debida a la acción del gen dominante incompleto, y alelos dominantes se asociaron principalmente con menores valores LD-1.
