Resumo: | Local varieties of sweet corn from the far west of Santa Catarina, southern Brazil, show outstanding potential for several important agronomic traits aimed at sweet corn genetic breeding. However, there is no data in the literature on the general and specific combining ability of these varieties for the chemical quality of the grains and the interactions of the general and specific combining ability with the environment. The percentage of total soluble sugars, starch content, and the relationship between sugars and starch of the grains were evaluated in experiments designed in complete randomized blocks, with two replications, in two environments of this region. The splitting of the diallel analysis into general and specific combining ability indicated a predominance of non-additive effects for all evaluated traits and showed non-significant effects (p ≤ 0.05) of the interactions of the general and specific combining ability x environment. Varieties 2255A and 2276A presented a higher concentration of favorable alleles for increasing the chemical quality of grains. The intervarietal hybrids F1's 2255A x 319A, 2255A x 2029A, 2255A x 2276A, Cubano x 2276A, 2276A x 2029A and 2255A x 741B stood out for interpopulation improvement. The biparental compounds derived from the combinations 2255A x 319A and 2255 x 2276A, the triple compound 2255A x 2276A x 2029A, and the quadruple compounds 2255A x 741B x 2276A x 319A and 2255A x 2276A x 2029A x 319A are the most suitable for the formation of composite populations followed by a cyclic process of recurrent selection, aiming to increase the chemical quality of the grains. |

Sin embargo, no existen datos en la literatura sobre las capacidades combinatorias general y específica de estas variedades para la calidad química de los granos, así como sobre los efectos de sus interacciones con el ambiente. El porcentaje de azúcares solubles totales, porcentaje de almidón y la relación azúcares y almidón de los granos se evaluaron en experimentos diseñados en bloques completos al azar, con dos repeticiones, en dos ambientes de esta región. La división del análisis dialélico para capacidad combinatoria general y específica mostró predominancia de efectos no aditivos para todos los rasgos evaluados y no presento significancia (p ≤ 0.05) de las interacciones de las capacidades combinatorias general y específica x ambiente. Las variedades 2255A y 2276A presentan mayor concentración de genes favorables para incrementar la calidad química de los granos. Los híbridos inter varietales F1's 2255A x 319A, 2255A x 2029A, 2255A x 2276A, Cubano x 2276A, 2276A x 2029A y 2255A x 741B se destacaron para el mejoramiento inter poblacional. Los compuestos biparentales derivados de las combinaciones 2255A x 319A y 2255 x 2276A, el compuesto triple 2255A x 2276A x 2029A y los compuestos cuádruples 2255A x 741B x 2276A x 319A y 2255A x 2276A x 2029A x 319A son los más adecuados para la formación de poblaciones compuestas, seguidas de selección poblacional, dirigido al aumento de la calidad química de los granos.Variedades locais de milho doce cultivadas no extremo Oeste de Santa Catarina, na região Sul do Brasil, apresentam notável potencial para diversos caracteres agronômicos importantes no melhoramento genético de milho doce. Entretanto, inexistem dados na literatura sobre as capacidades geral e específica de combinação destas variedades para a qualidade química dos grãos, bem como os efeitos de suas interações com o ambiente. A porcentagem de açúcares solúveis totais, porcentagem de amido e relação entre açúcares e amido dos grãos foram avaliadas a partir de experimentos delineados em blocos completos casualizados, com duas repetições, em dois ambientes desta região. O desdobramento da análise dialélica em capacidade geral e capacidade específica de combinação indicou predominância de efeitos não aditivos para todos os caracteres avaliados e evidenciou efeitos não significativos (p ≤ 0,05) das interações das capacidades geral e específica de combinação x ambiente. As variedades 2255A e 2276A apresentaram maior concentração de alelos favoráveis para o aumento da qualidade química dos grãos. Os híbridos intervarietais F1’s 2255A x 319A, 2255A x 2029A, 2255A x 2276A, Cubano x 2276A, 2276A x 2029A e 2255A x 741B destacaram-se para o melhoramento interpopulacional. Os compostos biparentais derivados das combinações 2255A x 319A e 2255 x 2276A, o composto triplo 2255A x 2276A x 2029A, e os compostos quádruplos 2255A x 741B x 2276A x 319A e 2255A x 2276A x 2029A x3 19A são os mais indicados para a formação de populações compostas, visando o aumento da qualidade química dos grãos, a partir de um processo cíclico de seleção recorrente.Research, Society and Development2022-05-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2941710.33448/rsd-v11i6.29417Research, Society and Development; Vol. 11 No. 6; e59411629417Research, Society and Development; Vol. 11 Núm. 6; e59411629417Research, Society and Development; v. 11 n. 6; e594116294172525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/29417/25542Copyright (c) 2022 Rose Mari Seledes; Juliana Bernardi Ogliari; Rosenilda de Souzahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSeledes, Rose MariOgliari, Juliana Bernardi Souza, Rosenilda de 2022-05-13T18:04:10Zoai:ojs.pkp.sfu.ca:article/29417Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:46:30.372423Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
