Various abiotic stress factors impose negative effect on plant growth and productivity (Shahzad et al., 2012), among them salt stress is one of major factor that drastically reduce crop plant growth and development (Azadi et al., 2015). Salinity affects 800 mh land area in arid and semi-arid environment (Ahmad et al., 2013). Wheat (Triticum aestivum) is staple food and primary crop plant in Pakistan (Batool et al., 2016). Farmers in Pakistan grow wheat in an area nine thousand hectares and 3.1% contribution in an annual GDP. Although enhancement of wheat tolerance for salt stress is main concern but, salt tolerance through physiological, biochemical and genetic mechanism is complex trait (Genc et al., 2010). Wheat plant exhibits many QTLs that enhance salt tolerance in this species (Ma et al., 2007; Munns and Tester, 2008). Genetic markers development revealed genetic architecture of salt tolerance trait. This help to analyzed individual QTLs playing role in salt tolerance (Ghaedrahmati et al., 2014). Number of scientist mapped QTLs related to salt tolerance mainly linked with morphological and yield trait (ElHendawy et al., 2009; Genc et al., 2010; Amin and Ayman, 2013; Mahdinejad et al., 2014; Azadi et al., 2015). Present study differs from above mention studies because it identifies QTLs in wheat mapping population connected to salt tolerance at germination and early seedling growth stage. Shahzad et al. (2012) describes that seed germination and seedling growth is utmost vulnerable phase to salinity and germination ability of wheat plant & is controlled by many genes (Song et al., 2005). In order to develop salt tolerant line it is very important to identify salt tolerance mechanism at seedling stage. Simple sequence repeats (SSR) are being used in present study to categorize QTLs linked to salinity tolerance at seed germination and early seedling growth stage.
