Resumo: | The phase of genotype evaluation for recommendation in different environments is seen as the key stage of breeding programs, in view of the importance of the genotype – environment interaction on the main traits. The objective of this study was to evaluate different field corn, popcorn, white corn, and sweet corn genotypes for their capacity of baby corn production and the genotype - environment interaction. Twenty-nine genotypes were evaluated, in a randomized complete block design with three replications. The experiments were performed in the main and second season in Rio Verde – GO and in the second season in Maringá – PR. Significant (p < 0.05) differences between the genotypes were observed for all evaluated traits. The genotype - environment interaction was only significant for mean ear diameter, prolificacy and ear yield, indicating a differentiated performance between genotypes in response to environmental variations. The predominance of the complex part of interaction on prolificacy and yield is emphasized. Although the baby corn harvest is performed even before ear fertilization, the results suggests that the variations in the traits related with babycorn production and quality are mainly influenced by genetic-environmental factors. The genotypes P30K64, HD 332, IPR 119, and IAC 125 obtained the highest means for the evaluated traits. The groups of white and field corn genotypes stood out for with a significantly better performance than the others, principally for ear yield. |

O objetivo deste trabalho foi avaliar diferentes genótipos de milho, milho pipoca, milho branco e milho doce com relação a capacidade de produção de minimilho e a interação genótipos por ambientes. Foram avaliados 29 genótipos, no delineamento em blocos ao acaso com três repetições. Os experimentos foram conduzidos na safra verão e safrinha de Rio Verde – GO e na safrinha de Maringá – PR. Foram observadas diferenças significativas (p < 0,05) entre genótipos em todas as características avaliadas e interação genótipos x ambientes apenas para diâmetro médio de espiguetas, prolificidade e produtividade de espiguetas, evidenciando ocorrer resposta distinta dos genótipos em função das variações ambientais. Ressalta-se a predominância da parte complexa da interação na prolificidade e produtividade de espiguetas. Embora a colheita de minimilho seja realizada antes mesmo da fecundação, os resultados sugerem que as características relacionadas a produção e qualidade de minimilho são afetadas pela interação genótipo-ambiente. Os genótipos P30K64, HD 332, IPR 119 e IAC 125 obtiveram as maiores médias entre as características avaliadas. Destacam-se os grupos de genótipos de milho branco e milho comum, com significativa superioridade em relação aos demais, principalmente para a produtividade de espiguetas.UEL2020-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3331110.5433/1679-0359.2020v41n2p383Semina: Ciências Agrárias; Vol. 41 No. 2 (2020); 383-394Semina: Ciências Agrárias; v. 41 n. 2 (2020); 383-3941679-03591676-546Xreponame:Semina.
