| contents | Performance of grain sorghum hybrids in soils with low and high aluminum saturation Crislene Vieira dos Santos Nataly Sousa Silva Jurandir Vieira Magalhães Robert Eugene Schaffert Cícero Beserra de Menezes Agrociencias plant breeding abiotic stress Sorghum bicolor aluminum tolerance 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. 2018 artículo científico 1517-6398 https://www.redalyc.org/articulo.oa?id=253067973002 https://www.redalyc.org/journal/2530/253067973002/ https://www.redalyc.org/journal/2530/253067973002/html/ https://www.redalyc.org/journal/2530/253067973002/253067973002.epub https://www.redalyc.org/journal/2530/253067973002/movil en http://www.redalyc.org/revista.oa?id=2530 Pesquisa Agropecuária Tropical application/pdf Universidade Federal de Goiás Pesquisa Agropecuária Tropical (Brasil) Num.1 Vol.48 |
