Resumo: | Upland cotton fiber is one of the most used natural fibers in the production of textile materials worldwide. For this reason, the selection of genotypes that meet the industry’s requirements is one of the main goals of cotton breeding programs. This study aimed to estimate the phenotypic and genotypic correlations among fiber traits and identify the direct and indirect effects of these traits on seed cotton yield of upland cotton genotypes in the semi-arid Brazilian Northeast. This study assessed 21 upland cotton genotypes from a complete diallel cross without reciprocals. The design was randomized blocks, with three replications and 21 treatments. The experiment was conducted in the municipality of Patos - PB, in 2015. The statistical analysis consisted of analysis of variance by the F test, phenotypic and genotypic correlation analysis, and path analysis. The studied materials revealed genetic variability for all traits. Path analysis has shown that the traits fiber elongation, fiber strength, and fiber fineness have a direct positive effect on seed cotton yield. |

Portanto, a seleção de genótipos que atendam às exigências desta indústria é um dos principais objetivos dos programas de melhoramento do algodoeiro. O objetivo deste estudo foi estimar as correlações fenotípicas e genotípicas entre as características tecnológicas da fibra e identificar os efeitos diretos e indiretos destas características sobre a produtividade de algodão em caroço de genótipos de algodoeiro herbáceo no semiárido nordestino. Foram avaliados 21 genótipos de algodoeiro herbáceo provenientes de um cruzamento dialélico completo sem os recíprocos. O delineamento utilizado foi blocos completos ao acaso, com três repetições. O experimento foi conduzido no município de Patos - PB, em 2015. As análises estatísticas consistiram de análise de variância pelo teste F, análise de correlação fenotípica e genotípica e análise de trilha. Todas as características apresentaram variabilidade genética entre os genótipos estudados. A correlação fenotípica foi positiva entre CSP, COMP, UNF e RES. Foram observados efeitos indiretos de ALON, COMP e FIN sobre PROD, por meio das variáveis FIN, RD e +b.EDUFU2019-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4240810.14393/BJ-v35n6a2019-42408Bioscience Journal ; Vol. 35 No. 6 (2019): Nov./Dec.; 1855-1861Bioscience Journal ; v. 35 n. 6 (2019): Nov./Dec.; 1855-18611981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/42408/27470Brazil; ContemporaryCopyright (c) 2019 Damião Ranieri Queiroz, Francisco José Correa Farias, José Jaime Vasconcelos Cavalcanti, Luiz Paulo de Carvalho, Diogo Gonçalves Neder, Gérsia Gonçalves MELOde Melo, Djayran Sobral Costa, Filipe Cavalcanti Farias, Paulo Eduardo Teodorohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessQueiroz, Damião Ranieri Farias, Francisco José Correa Cavalcanti, José Jaime Vasconcelos Carvalho, Luiz Paulo de Neder, Diogo GonçalvesMELOde Melo, Gérsia Gonçalves Costa, Djayran Sobral Farias, Filipe Cavalcanti Teodoro, Paulo Eduardo2022-01-24T13:56:09Zoai:ojs.www.seer.ufu.br:article/42408Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-24T13:56:09Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
