Development of linkage map in F2 population of selected parents with respect to Macrophomina phaseolina resistance trait using screened polymorphic RAPD and developed SCAR markers of jute

Abstract: Two molecular markers (RAPD and simple sequence repeat (SSR)) were applied on 12 Corchorus capsularis jute samples. Two of them were Macrophomina phaseolina-resistant and the remaining eight were M. phaseolina-susceptible accessions. Eleven SSR primer combinations out of 18 gave the polymorphic results between M. phaseolina-resistant and -susceptible accessions. Five pairs of sequence characterised amplified region (SCAR) primers designated as SCP-4, SCS-3, SCS-13, SCG-10 and SCU-10 were designed based on the polymorphic loci obtained between JRC-412 and CIM-036. Only SCU-10 and SCS-13 produced polymorphic markers corresponding to OPU-10 and OPS-13 amplified from 'CIM-036' and JRC-412, respectively. RAPD and SCAR markers were employed for construction of a linkage map using a set of 67 F2 population of a cross between JRC-412 and CIM-036 as a mapping population. Nine markers were assigned to two linkage groups (LGs) covering a total length of 628.4 cM with an average distance of 28 cM between markers.
