Resumo: | The objective of this study was to check whether there is linear dependence between phenological, morphological and production traits and tassel traits in maize genotypes. Seven experiments were conducted with 16 maize genotypes, in a randomized block design, with three replicates. Four groups of traits were evaluated: phenological (two), morphological (three), production (four) and tassel (11). Joint analysis of variance and F test at 5% significance level were performed. The matrix of phenotypic correlation coefficients between the traits was estimated and multicollinearity was diagnosed in each group of traits. Associations between the groups of traits were checked by canonical correlation analysis. There is linear dependence between phenological, morphological and production traits and tassel traits in maize genotypes. Phenological (number of days from sowing to 50% of male flowering and number of days from sowing to 50% of female flowering), morphological (plant height and spike height) and production (number of spikes and grain yield) traits are positively associated with tassel traits (tassel branch number and tassel dry matter). Tassel branch number and tassel dry matter can be used for indirect selection of maize plants. |

Foram conduzidos sete experimentos com 16 genótipos de milho, no delineamento experimental blocos ao acaso, com três repetições. Foram avaliados quatro grupos de caracteres: fenológicos (dois), morfológicos (três), produtivos (quatro) e de pendão (11). A análise de variância conjunta e o teste F a 5% de significância foram realizados. A matriz de coeficientes de correlação fenotípica entre os caracteres foi estimada e realizado o diagnóstico de multicolinearidade, em cada grupo de caracteres. As associações entre os grupos de caracteres foram verificadas por meio da análise de correlação canônica. Há dependência linear entre os caracteres fenológicos, morfológicos e produtivos com os caracteres de pendão em genótipos de milho. Os caracteres fenológicos (número de dias da semeadura até 50% do florescimento masculino e número de dias da semeadura até 50% do florescimento feminino), morfológicos (altura de planta e altura de inserção da espiga) e produtivos (número de espigas e produtividade de grãos) estão associados positivamente aos caracteres de pendão (número de ramificações e matéria seca do pendão). O número de ramificações e a matéria seca do pendão podem ser utilizados para seleção indireta de plantas de milho.Universidade Federal Rural do Semi-Árido2023-07-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1136910.1590/1983-21252023v36n309rcREVISTA CAATINGA; Vol. 36 No. 3 (2023); 561-571Revista Caatinga; v. 36 n. 3 (2023); 561-5711983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/11369/11283Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessSilveira, Daniela LixinskiCargnelutti Filho, Alberto Neu, Ismael Mario Márcio Bubans, Valéria EscaioOsmari, Bruno FillipinOsmari, Lucas Fillipin2023-07-18T12:27:56Zoai:ojs.periodicos.ufersa.edu.br:article/11369Revistahttps://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:2024-04-29T09:47:03.219293Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
