Abstract Background Sesame (Sesamum indicum L., 2n = 2x = 26) is an important oilseed crop with high oil content but small seed size. To reveal the genetic loci of the quantitative seed-related traits, we constructed a high-density single nucleotide polymorphism (SNP) linkage map of an F2 population by using specific length amplified fragment (SLAF) technique and determined the quantitative trait loci (QTLs) of seed-related traits for sesame based on the phenotypes of F3 progeny. Results The genetic map comprised 2159 SNP markers distributed on 13 linkage groups (LGs) and was 2128.51 cM in length, with an average distance of 0.99 cM between adjacent markers. QTL mapping revealed 19 major-effect QTLs with the phenotypic effect (R2) more than 10%, i.e., eight QTLs for seed coat color, nine QTLs for seed size, and two QTLs for 1000-seed weight (TSW), using composite interval mapping method. Particularly, LG04 and LG11 contained collocated QTL regions for the seed coat color and seed size traits, respectively, based on their close or identical locations. In total, 155 candidate genes for seed coat color, 22 for seed size traits, and 54 for TSW were screened and analyzed. Conclusions This report presents the first QTL mapping of seed-related traits in sesame using an F2 population. The results reveal the location of specific markers associated with seed-related traits in sesame and provide the basis for further seed quality traits research.

The yellow seed coat trait in No. 2127-17, a resynthesized purely yellow Brassica napus line, is controlled by a single partially dominant gene, Y. A double-haploid population derived from the F1 of No. 2127-17 × ‘ZY821’ was used to map the seed coat color phenotype. A combination of AFLP analysis and bulked segregant analysis identified 18 AFLP markers linked to the seed coat color trait. The 18 AFLP markers were mapped to a chromosomal region of 37.0 cM with an average of 2.0 cM between adjacent markers. Two markers, AFLP-K and AFLP-H, bracketed the Y locus in an interval of 1.0 cM, such that each was 0.5 cM away from the Y locus. Two other markers, AFLP-A and AFLP-B, co-segregated with the seed color gene. For ease of use in breeding programs, these 4 most tightly linked AFLP markers were converted into reliable PCR-based markers. SCAR-K, which was derived from AFLP-K, was assigned to linkage group 9 (N9) of a B. napus reference map consisting of 150 commonly used SSR (simple sequence repeat) markers. Furthermore, 2 SSR markers (Na14-E08 and Na10-B07) linked to SCAR-K on the reference map were reversely mapped to the linkage map constructed in this study, and also showed linkage to the Y locus. These linked markers would be useful for the transfer of the dominant allele Y from No. 2127-17 to elite cultivars using a marker-assisted selection strategy and would accelerate the cloning of the seed coat color gene.
