Identification of genetic factors responsible for controlling germination traits in salt stress condition can be helpful to identify and develop salt tolerant cultivars. Present study was designed to identify quantitative trait loci (QTL) related to germination traits using F7 mapping population RILs derived from cross between Pasban-90 (salt tolerant) and Frontana (salt susceptible). Composite interval mapping (CIM) was used for QTL analysis of germination percentage, germination index, seedling vigor index, root length, shoot length, fresh weight and dry weight. This analysis resulted in the identification of 26 QTLs under salt stress and 18 QTLs under control condition. Seven major QTLs (QFW.6A, QDW.6A, QRL.6A, QFW.3B, QFW.6B, QRL.6D and QSL.6D) were mapped on 6A, 3B, 6B and 6D in control treatment and 11 main QTLs were detected under stress condition. We identified shared location for root length, shoot length and fresh weight on 3D in xgdm8-xgwm314. Shoot length and root length QTL detected in interval xcfd13-xgwm132 on 6D.
