JF - <i>Electronic Journal of Plant Breeding</i> JA - EJPB VL - 9 IS - 1 SE - Research Article DO - UR - https://ejplantbreeding.org/index.php/EJPB/article/view/2592 AB - A population of 188 RIL’s derived from a cross involving progenitor species Sesamum malabaricum Burm. was used for genetic analysis and mapping of QTLs for yield contributing traits. A total of 60 SSR markers were developed through genomic hybridization assay, of which 12 were found to be polymorphic. Of the total 101 SSR markers screened, 35 markers were found segregating in expected 1:1 ratio and were selected for mapping. The linkage map constructed contained 26 markers in three linkage groups covering a distance of 298.6cM, 694.4cM and 86.4cM respectively. Analysis of population structure identified the presence of 3 clusters (K=3) of parents and recombinants. QTLs for branches/plant, days to 50% flowering, capsules/ node, seed weight per capsule, seed yield per plant, 100 seed weight, internode lengths, stem girth, capsules/ node, days to maturity and node with capsules were mapped.
