Resumo: | The African eggplant is a solanaceous vegetable with bitter tasting immature fruit of various colors (light green, dark green, white) and shapes (from elongated to round). Because it is a little known vegetable, there are few studies on the inheritance of its economically important traits. The objective of this work had was to study the inheritance of shape and immature fruit color in S. gilo, in order to assist future breeding programmes with this crop. Cultivars Morro Redondo (MR, with dark green round fruit) and Comprido Verde Claro (CVC, with elongated light green fruit) were tested alond with their F1(MR x CVC), F2(MRxCVC), BC11[MRx(MRxCVC)], and BC12[CVCx(MRxCVC) generations. A test based on maximum likelihood was used to test the hypothesis of monogenic control fruit length (L), diameter (D) and L/D ratio. Fruit diameter was under control of a major gene locus with additive effects, plus polygenes also with additive effects. Fruit length and L/D ratio were under control of polygenes with predominantly additive effects. Fruit color was determined by a major gene locus with two alleles, with dominance of the allele that controls dark green over light green color, but there was also evidence for the presence of modifier genes. |

Por ser una especie poco extendida a nivel mundial, los modos de herencia de sus características de importancia económica han sido poco estudiados. El objetivo de este trabajo fue determinar la herencia de color y forma de frutos de berenjena. Se utilizaron semillas de Morro Redondo (MR), Comprido Verde-Claro (CVC) y cruces y retrocruces: F1(MRxCVC), F2(MRxCVC), RC11[MRx(MRxCVC)], RC12[CVCx(MRxCVC)]. La función de máxima verosimilitud probó la existencia de un gen más grande que controla la longitud de los caracteres (C), el diámetro (D) y la relación C/D. En cuanto al color de los frutos inmaduros, se probó la hipótesis de herencia monogénica mediante la prueba de chi-cuadrado. El diámetro de la fruta está controlado por un gen más grande solo con efecto aditivo, más poligenes solo con efecto aditivo. La longitud del fruto y la relación C/D están controladas poligénicamente por genes cuyos efectos son predominantemente aditivos. El color de los frutos inmaduros está controlado por un gen más grande con dos alelos, el alelo que confiere la coloración verde oscuro es dominante sobre el alelo que confiere la coloración verde claro, sin embargo, hay indicios de genes modificadores involucrados.O jiló é uma solanácea com frutos de cores (verde-escuros, verde-claros, brancos) e formatos (de redondo a alongado) variados. Por tratar-se de uma espécie pouco difundida mundialmente, têm sido pouco estudados os modos de herança de suas características de importância econômica. O objetivo deste trabalho foi determinar a herança de cor e formato de frutos de jiló. Foram utilizadas sementes das variedades Morro Redondo (MR), Comprido Verde-Claro (CVC) e dos cruzamentos e retrocruzamentos: F1(MRxCVC), F2(MRxCVC), RC11[MRx(MRxCVC)], RC12[CVCx(MRxCVC)]. A existência de um gene maior no controle dos caracteres comprimento (C), diâmetro (D) e relação C/D foi testada pela função de máxima verossimilhança. Já para cor de frutos imaturos, foi testada a hipótese de herança monogênica, pelo teste de chi-quadrado. O diâmetro do fruto é controlado por um gene maior com efeito aditivo apenas, mais poligenes com efeitos aditivos apenas. O comprimento do fruto e a relação C/D são controlados poligenicamente, por genes cujos efeitos são predominantemente aditivos. A cor dos frutos imaturos é controlada por um gene maior com dois alelos, sendo o alelo que confere a coloração verde-escura dominante sobre o alelo que confere a coloração verde-clara, porém, há indícios de genes modificadores envolvidos.Research, Society and Development2022-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2618510.33448/rsd-v11i3.26185Research, Society and Development; Vol. 11 No. 3; e52211326185Research, Society and Development; Vol. 11 Núm. 3; e52211326185Research, Society and Development; v. 11 n. 3; e522113261852525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/26185/23492Copyright (c) 2022 André Lasmar; Luis Felipe Lima e Silva; Regis de Castro Carvalho; Ranoel José de Sousa Gonçalves; Thiago Matos Andrade; Wilson Roberto Malufhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLasmar, AndréSilva, Luis Felipe Lima e Carvalho, Regis de Castro Gonçalves, Ranoel José de Sousa Andrade, Thiago Matos Maluf, Wilson Roberto 2022-03-09T13:44:38Zoai:ojs.pkp.sfu.ca:article/26185Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:17.366755Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
