Resumo: | The rich genetic diversity and wide adaptation of rice (Oryza sativa L.) to different environments provide fundamental resources for its conservation and improvement. The analysis of canonical correlations can be used to increase the efficiency of selecting superior genotypes, as several traits are evaluated simultaneously. Thus, this study aimed to compare morphoagronomic traits and estimate the magnitude of the association and interdependence between two groups of traits in genotypes of special types of rice. The experiment was carried out between November 2020 and April 2021 at the Department of Plant Science of the Federal Rural University of Rio de Janeiro (UFRRJ), Seropédica – RJ. The experimental design consisted of randomized blocks, with four replications. Seventeen genotypes were evaluated, five of them consisting of white rice and eleven special types of rice. Two groups of variables were used to determine the canonical correlations, with group I composed of four morphological traits and group II composed of four yield components. Significant differences (P<0.01) were observed between genotypes for the eight evaluated traits. The first, second, and third pairs showed significant canonical correlations at a 5% probability, demonstrating that these groups are not independent. The selection of superior genotypes for production can be based on choosing plants with higher flag leaf thickness, higher height, and lower flag leaf angle. |

A análise de correlações canônicas pode ser utilizada para aumentar a eficiência de seleção de genótipos superiores, pois várias características são avaliadas simultaneamente. Diante do exposto, este trabalho teve por objetivo comparar características morfoagronômicas e estimar a magnitude da associação e interdependência entre dois grupos de características em genótipos de tipos especiais de arroz. O ensaio foi realizado entre novembro de 2020 e abril de 2021, no Departamento de Fitotecnia da Universidade Federal Rural do Rio de Janeiro (UFRRJ), Seropédica – RJ. O delineamento experimental foi o de blocos ao acaso, com quatro repetições. Foram avaliados dezessete genótipos, dos quais cinco de arroz branco e onze de tipos especiais. Para a determinação das correlações canônicas foram utilizados dois grupos de variáveis, sendo o grupo I composto por quatro características morfológicas e o grupo II composto por quatro componentes da produção. Houve diferenças significativas (P<0,01) entre os genótipos para as oito características avaliadas. O primeiro, o segundo e terceiro pares apresentaram correlações canônicas significativas a 5% de probabilidade, demonstrando que esses grupos não são independentes. A seleção de genótipos superiores, para produção, pode basear-se na escolha de plantas com maior espessura da folha bandeira, maior altura e menor ângulo da folha bandeira.Universidade Federal Rural do Semi-Árido2022-09-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1109810.1590/1983-21252022v35n403rcREVISTA CAATINGA; Vol. 35 No. 4 (2022); 764-771Revista Caatinga; v. 35 n. 4 (2022); 764-7711983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/11098/11041Copyright (c) 2022 Revista Caatingainfo:eu-repo/semantics/openAccessXavier, Mariana Caroline GuimarãesAraújo, Juliana CorrêaMenezes, Bruna Rafaela da Silva Damasceno Júnior, Pedro Corrêa2023-06-30T17:48:52Zoai:ojs.periodicos.ufersa.edu.br:article/11098Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:47:01.777929Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
