Identification of novel source of salt tolerance in local bread wheat germplasm using morpho-physiological and biochemical attributes

Abstract Salt tolerant wheat cultivars may be used as genetic resource for wheat breeding to ensure yield stability in future. The study was aimed to select salt tolerant cultivar(s) to identify novel source of salt tolerance in local wheat germplasm. Initially, 40 local wheat cultivars were screene...
