ABSTRACT: This study assessed the agronomic performance and estimate the adaptability and stability of biomass sorghum genotypes in different regions of Brazil. Twenty-five sorghum genotypes were evaluated in experiments conducted in Goiânia (Goiás State-GO), Sobral (Ceará state-CE), Jaguariúna (São Paulo State-SP), Nova Porteirinha (Minas Gerais State-MG), Planaltina (GO), Sete Lagoas (MG), Narandiba (SP), Vilhena Rondônia State (RO) and Terra Rica (Paraná State-PR), in the 2021/2022 growing season. A randomized block design was used, with three repetitions. Pooled analysis of variance was conducted for the traits plant height, flowering, dry and fresh matter yield, and dry matter content. The adjusted means were grouped by the Scott-Knott test (P < 0.05). Adaptability and stability were evaluated using Annicchiarico’s method. Biomass sorghum genotypes have a longer cycle, greater height and higher yields than their forage sorghum counterparts. The experimental hybrids 202129B014 and 202129B016 and commercial hybrid BRS 716 exhibited high dry and fresh matter yields, general adaptability and high stability for all the environments studied.
