Kernel color is an important characteristic of foxtail millet (Setaria italica) associated with its market ability, quality, and nutritional value, which mainly due to the accumulation carotenoids. Despite importance, genetic basis carotenoid variation in remains largely unexplored. Herein, molecular mechanisms governing kernel were investigated by exhaustive methodology encompassing Genome-Wide Association Study (GWAS), Bulk Segregant Analysis sequencing (BSA-seq), integrated transcriptomic metabolomic analyses. The total content kernels across 201 germplasms showed a spectrum variations, indicated that quantitative trait controlled multiple genes. Using GWAS on these BSA-seq F6 generation Recombinant Inbred Line (RIL) population derived from GBS (yellow kernel) NMB (white cross, we identified genome regions linked kernels. Integrated profiling during grain filling both yellow white varieties pinpointed SiPSY1 SiCCD1 as key genes controlling accumulation. Notably, SNP (G/A) at 364 bp Indel (29 insertion) 856 within promoter predominantly contributed variance activity. These variations markedly affected expression levels, ultimately determining phenotypic difference between findings provide crucial insights for involved metabolism lay solid foundation breeding millet.
