The aim of this study was to evaluate the agronomic characteristics of 25 hybrids of sorghum for double cropping in Jataí, State of Goiás, Brazil. An experiment was installed in a randomized block design with three replications. The characteristics evaluated were: number of days between sowing and booting; number of days between sowing and flowering; plant height; panicle length, thousand grain weight and yield. It was found that the hybrids did not differ regarding the boot stage, flowering and plant height. For the panicle length, the hybrids 1167017, 1170017 and 1169074 stood out. The hybrids DKB550, 1237030, 1170017, 1167017 and 1099044 showed higher thousand grain weight. For yield , the hybrids 1238020, 1169092, 1G244, 843009, 1236020, 1099034, 1167053, BRS330, 1105661, 1099044, 1105653, 1167017, 729033 and 1167093 showed higher yields, which can be linked to higher soil and climatic adaptation.
