This book was an effort for wheat improvement under salinity stress.One hundred and eighty seven wheat genotypes were evaluated at germination, vegetative and maturity stage under 200, 250 and 300 mM NaCl stress.Various morphological and molecular markers were utilized to screen salt tolerant cultivars. Vegetative stage was found to be most salinity sensitive stage. Therefore, genotypes should be evaluated at this stage by using molecular, physiological, morphological and biochemical approaches. More than 10 SSR markers were found to be linked with salinity tolerance.Heritability estimates and gene action studies revealed that potential for improving salinity tolerance in wheat does exist.
