Interpretive Summary:

Technical Abstract: Excess salinity affects the growth and development of all plants. Salinization jeopardizes agroecosystems, induces oxidative reactions in most cultivated plants and reduces biomass to directly affect crop yield. Some plants are affected more than others, depending upon their ability to withstand salt stress. The plants which can tolerate a high amount of salts in soil without compromising yield are called halophytes. In contrast, plants which are salt sensitive and perform poorly under salt stress are called glycophytes. Among the cultivated crops in Pakistan, cotton is moderately tolerant to salt stress. The basic pillar of plant breeding is to have genetic variation in available germplasm for acquired characteristics. For the development of salt tolerant cotton genotypes, the variation from higher to lower for salt stress tolerance enhancing parameters (morphological, physiological and biochemical) is a pre-requisite followed by indirect selection or hybridization programs. Limited success has been achieved in the development of salt tolerant genotypes because it is dependent on many factors and is not completely understood at the molecular level. However, advancement in biochemical and molecular studies has made it possible to explore complex traits through transcriptomic profiling under salt stress.
