Resumo: The presence of aluminum (Al3+) in acidic soils is one of the main causes of low crop yield, since it inhibits the root growth, thus affecting the nutrients and water uptake by plants. An approach to grow crops in areas with high Al3+ saturation is the use of tolerant cultivars. This study aimed to evaluate commercial sorghum hybrids in soils with low and high aluminum saturation, in order to select cultivars with high grain yield, even when exposed to abiotic stress. Twenty hybrids were evaluated for characteristics such as plant flowering, plant height and grain yield. All three traits were significantly affected by Al3+, being grain yield the most affected one. Despite the significant genotypes x environments interaction for grain yield, it was possible to select hybrids with yield above the national average in both environments. The hybrids BRS373, 50A50, AS4639, DKB540, AS4625, A9721R, 1167092, DKB550, 1G282 and AG1040 showed a high yield under low and high Al-saturation conditions.

Uma abordagem para o cultivo em áreas com alta saturação por Al3+ é a utilização de cultivares tolerantes. Objetivou-se avaliar híbridos comerciais de sorgo granífero em solos com baixa e alta saturação por Al3+, a fim de selecionar cultivares com alta produtividade de grãos, mesmo quando expostas a estresse abiótico. Avaliaram-se 20 híbridos, quanto às características de florescimento, altura de plantas e produtividade de grãos. As três características foram prejudicadas pelo Al3+, sendo a produtividade de grãos a mais afetada. Apesar de a interação genótipos x ambientes ser significativa para produtividade de grãos, foi possível selecionar híbridos com produtividade acima da média em ambos os ambientes. Os híbridos BRS373, 50A50, AS4639, DKB540, AS4625, A9721R, 1167092, DKB550, 1G282 e AG1040 apresentaram alta produtividade nas condições de baixa e alta saturação por Al3+.Escola de Agronomia - Universidade Federal de Goiás2018-02-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/48851Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 48, n. 1, Jan./Mar. 2018; 12-18Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 48, n. 1, jan./mar. 2018; 12-18Pesquisa Agropecuária Tropical; v. 48, n. 1, jan./mar. 2018; 12-181983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/48851/25163Copyright (c) 2018 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessVieira dos Santos, CrisleneSousa Silva, NatalyVieira Magalhães, JurandirEugene Schaffert, RobertBeserra de Menezes, Cícero2020-07-13T18:58:12Zoai:ojs.revistas.ufg.br:article/48851Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:17.913104Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
