Abstract Oilseed crops are used to produce vegetable oil. Sesame ( Sesamum indicum ), an oilseed crop grown worldwide, has high oil content and a small diploid genome, but the genetic basis of production quality is unclear. Here we sequence 705 diverse sesame varieties construct haplotype map genome de novo assemble two representative identify variations. We investigate 56 agronomic traits in four environments 549 associated loci. Examination major loci identifies 46 candidate causative genes, including genes related content, fatty acid biosynthesis yield. Several for encode enzymes involved metabolism. Two with lignification black pigmentation seed coat also large variation content. These findings may inform breeding improvement strategies broad range crops.
