Resumo: | The objectives of this work were to assess heterosis and its components in F1 hybrids of a diallel cross among lines of scarlet eggplants (Solanum gilo Raddi, syn. S. aeth opicum L.), and to study the modes of gene action associated with its expression. 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. Traits under study were total yield, mean fruit mass and fruit length/diameter ratio. There was no evidence of epistatic gene action in the expression of any of the traits under study. Heterosis for yield could be explained by overdominance, but higher yields were only weakly associated with larger frequencies of dominant alleles an indication that yields may be markedly influenced by the action of relatively few loci with overdominant gene action. Heterosis for mean fruit mass was associated with incompletely dominant gene action, and larger fruit mass was associated with larger proportions of dominant alleles. For fruit length/diameter ration (L.D-1), heterosis was due to incompletely dominant gene action, and dominant alleles were predominantly associated with lower L.D-1values. |

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, Tingua, Iraja, 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 aleatório con cuatro repeticiones. Los rasgos estudiados fueron producción total, peso promédio del fruto y la relación  ongitud/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  rande 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.Universidad Autónoma del Estado de México (UAEM)2019-10-21T20:10:41Z2019-10-21T20:10:41Z2015-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfANDRADE, T.
