  abstract = {{S}orghum is a vital food and feed crop in the world's dry regions. {D}eveloping sorghum cultivars with high biomass production and carbon sequestration can contribute to soil health and crop productivity. {T}he objective of this study was to assess agronomic performance, biomass production and carbon accumulation in selected sorghum genotypes for production and breeding. {F}ifty sorghum genotypes were evaluated at three locations ({S}ilverton, {U}kulinga, and {B}ethlehem) in {S}outh {A}frica during 2022 and 2023 growing seasons. {S}ignificant genotype x location (p < 0.05) interactions were detected for days to 50% heading ({DTH}), days to 50% maturity ({DTM}), plant height ({PH}), total plant biomass ({PB}), shoot biomass ({SB}), root biomass ({RB}), root-to-shoot biomass ratio ({RS}), and grain yield ({GY}). {T}he highest {GY} was recorded for genotypes {AS}115 (25.08 g plant(-1)), {AS}251 (21.83 g plant(-1)), and {AS}134 (21.42 g plant(-1)). {G}enotypes {AS}122 and {AS}27 ranked first and second, respectively, for all the carbon stock parameters except for root carbon stock ({RC}s), whereas genotype {AS}108 had the highest {RC}s of 8.87 g plant(-1). {T}he principal component analysis identified {GY}, {DTH}, {PH}, {PB}, {SB}, {RB}, {RC}s, {RC}s/{SC}s, total plant carbon stock ({PC}s), shoot carbon stock ({SC}s), and grain carbon stock ({GC}s) as the most discriminated traits among the test genotypes. {T}he cluster analysis using agronomic and carbon-related parameters delineated the test genotypes into three genetic groups, indicating marked genetic diversity for cultivar development and enhanced {C} storage and sustainable sorghum production. {T}he selected sorghum genotypes are recommended for further breeding and variety release adapted to various agroecologies in {S}outh {A}frica.},
