Resumo: | The objective of this study was to check whether there are linear relations between production traits and grain protein in early-, medium- and late-cycle wheat. Data from 204 competition trials of wheat genotypes conducted in the states of Rio Grande do Sul and Paraná were used, 78 trials with early-cycle, 34 with medium-cycle and 92 with late-cycle genotypes. The trials were conducted in a randomized block design, with 149 early-cycle, 95 medium-cycle and 193 late-cycle genotypes being evaluated from 2015 to 2019. Three production traits (grain yield, in kg ha-1, thousand-grain weight, in g, and hectoliter weight, in kg hL-1) and grain protein, in %, were evaluated. Scatter plots were created and the partial correlation coefficients between these four traits were calculated, based on 4330, 2497 and 4714 observations, referring to the early, medium and late cycles, respectively. There are linear relations between production traits and grain protein in early-, medium- and late-cycle wheat. Early- and late-cycle wheat genotypes show a negative correlation between grain yield and grain protein. Medium-cycle wheat genotypes show no correlation between grain yield and grain protein. Selection of wheat genotypes with higher grain yield and hectoliter weight can be carried out indirectly by means of thousand-grain weight. |

Foram utilizados os dados de 204 ensaios de competição de genótipos de trigo conduzidos nos estados do Rio Grande do Sul e Paraná, sendo 78 ensaios com genótipos de ciclo precoce, 34 de ciclo médio e 92 de ciclo tardio. Os ensaios foram conduzidos no delineamento de blocos casualizados, sendo avaliados 149 genótipos de ciclo precoce, 95 de ciclo médio e 193 de ciclo tardio, nos anos de 2015 a 2019. Foram avaliados três caracteres produtivos (produtividade de grãos, em kg ha-1, peso de mil grãos, em g e peso do hectolitro, em kg hL-1) e a proteína dos grãos, em %. Foram confeccionados gráficos de dispersão e calcularam-se os coeficientes de correlação parcial entre esses quatro caracteres, a partir de 4330, 2497 e 4714 observações, dos ciclos precoce, médio e tardio, respectivamente. Há relações lineares entre caracteres produtivos e proteína em grãos de trigo de ciclos precoce, médio e tardio. Os genótipos de trigo de ciclos precoce e tardio apresentam correlação negativa entre a produtividade de grãos e a proteína nos grãos. Os genótipos de trigo de ciclo médio apresentam ausência de correlação entre produtividade de grãos e a proteína nos grãos. A seleção de genótipos de maior produtividade de grãos e peso do hectolitro pode ser realizada indiretamente por meio do peso de mil grãos.Universidade Federal Rural do Semi-Árido2024-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1231210.1590/1983-21252024v3712312rcREVISTA CAATINGA; Vol. 37 (2024); e12312Revista Caatinga; v. 37 (2024); e123121983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/12312/11454Copyright (c) 2024 Revista Caatingainfo:eu-repo/semantics/openAccessTrivisiol, Vinicius SeveroCargnelutti Filho, AlbertoFacco, GiovaniLoro, Murilo Vieira2024-04-22T17:59:20Zoai:ojs.periodicos.ufersa.edu.br:article/12312Revistahttps://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:2024-04-29T09:47:08.100730Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
