However, the molecular mechanisms underlying hull colour variation remain unknown.<h4>Results</h4>An F₇ recombinant inbred line (RIL) population containing 215 lines derived from Hongjiugu × Yugu18 was used to analyze inheritance and detect the quantitative trait loci (QTL) for four hull colour traits using major gene plus polygene mixed inheritance analysis and composite interval mapping (CIM) in four environments. Genetic analysis revealed that the hull colour L^* value (HCL^*) was controlled by two major genes plus additive polygenes, the hull colour a^* value (HCa^*) was controlled by three major genes, the hull colouBMC genomics458https://www.ebi.ac.uk/biostudies/studies/S-EPMC10428602biostudies-literatureMapping of major QTL and candidate gene analysis for hull colour in foxtail millet (Setaria italica (L.)
