  abstract = {{G}enome wide association studies ({GWAS}) are important in discerning the genetic architecture of complex traits such as biomass allocation for improving drought tolerance and carbon sequestration potential of wheat. {T}he objectives of this study were to deduce the population structure and marker-trait association for biomass traits in wheat under droughtstressed and non-stressed conditions. {A} 100-wheat ({T}riticum aestivum {L}.) genotype panel was phenotyped for days to heading ({DTH}), days to maturity ({DTM}), shoot biomass ({SB}), root biomass ({RB}), root to shoot ratio ({RS}) and grain yield ({GY}). {T}he panel was sequenced using 15,600 single nucleotide polymorphism ({SNP}s) markers and subjected to genetic analysis using the compressed mixed linear model ({CMLM}) at false discovery rate ({FDR} < 0.05). {P}opulation structure analysis revealed six sub-clusters with high membership ancestry coefficient of.0.65 to their assigned sub-clusters. {A} total of 75 significant marker-trait associations ({MTA}s) were identified with a linkage disequilibrium threshold of 0.38 at 5c{M}. {T}hirty-seven of the {MTA}s were detected under drought-stressed condition and 48% were on the {B} genome, where most quantitative trait loci ({QTL}s) for {RB}, {SB} and {GY} were previously identified. {T}here were seven pleiotropic markers for {RB} and {SB} that may facilitate simultaneous selection. {T}hirty-seven putative candidate genes were mined by gene annotation on the {IWGSC} {R}ef{S}eq 1.1. {T}he significant {MTA}s observed in this study will be useful in devising strategies for marker-assisted breeding for simultaneous improvement of drought tolerance and to enhance {C} sequestration capacity of wheat.},
