Biomass sorghum has been shown to be a very attractive crop, as it is not very demanding in terms of fertility, allows for a fully mechanized cultivation, and has a high productive potential for green mass. In order to verify adaptability to the city of Confresa-MT, this work analyzed 19 experimental hybrids of biomass sorghum, from the Improvement Program of Embrapa Corn and Sorghum, and a commercial cultivar (AGRI002E). The experimental design used was in randomized blocks, with 3 replications. The parameters analyzed were stem diameter at breast height (DAP), plant height (ALT), plant lodging resistance (RA), green mass yield (PMV), number of stalks (NC), mean panicle weight (PP), number of panicles (NP), and cycle. It was found that more productive cultivars had mostly greater height and diameter, in addition to greater resistance to lodging and later cycles, such as CMSXS7501, CMSXS7515 and AGRI002E, which stood out in these variables in relation to other cultivars, with yields above 140 t. ha-1. However, CMSXS7509 stands out from the others, for being characterized as a cultivar with expressive productivity, but presenting a short cycle (140 days).
