(Cicer arietinum L.) is one of the important legume rabi season crop in production among the world pulse crops. The aim of the study was to identify quantitative trait loci (QTLs) linked to seed yield and yield related traits in a recombinant inbred lines (RIL) derived from the cross of Fusarium wilt susceptible (JG62) and resistant (WR315). The population consisting of 125 RILs was grown under field condition over two seasons. The population were genotyped with sixty polymorphic markers and phenotyped for agronomic and yield related traits. A genetic map composed of two linkage groups (LGs) covering 768.92 cM was constructed. QTL analysis was performed by composite interval mapping (CIM) using ICIM QTL Mapping version 4.00 software. Total five QTLs were identified for productivity related traits with a LOD score from 3.18 to 11.42. One QTL (qPods 13-2-1) for number of pods per plant explaining a phenotypic variance (PVE) of 11.05% were observed in 2013, four QTLs were identified in 2014, two QTLs (qFlowering 14-1-1 and qFlowering 14-1-2) for days taken to 50% flowering explaining a PVE of 28.07% and 40.10% respectively and two QTLs (qTW 14-1-1 and qTW 14-2-1) for 100 seed weight explaining a PVE of 11.56% and 19.29% respectively. The identified markers could be used in marker assisted selection (MAS) in chickpea breeding programmes after validation.
