摘要：
Sorghum is a source of several minerals whose content may vary depending on the genotype and the production environment. The objective of this study was to screen sorghum genotypes for mineral content and to investigate the effect of water stress on it. A large variability was observed in the mineral content of 100 sorghum genotypes grown in environments without (WoWS) and with water stress (WthWS). The water stress decreased Mn, P, Mg and S contents in 100, 96, 93 and 56% of genotypes, respectively. The genotypes and other factors seemed to have more impact than water stress on K, Ca, Cu, Fe and Zn levels. In 100 sorghum genotypes, 2 were classified as excellent sources of Fe and 25 of Zn, in both environments. The best two genotypes to Fe content were SC21 and SC655 and to Zn were SC320 and SHAN-QUI-RED which showed great potential for use in biofortification. (C) 2016 Elsevier Ltd. All rights reserved.
