Abstract:
Among the abiotic stresses salinity and drought stresses are the major ones that cause severe losses to cotton yields. To cultivate the suitable ones that can tolerate those stresses is of great importance. Two parental cultivars CPD-813 and 8-1-2, which had been taken from ̔Multi Environment Stress Resistance System were screened for salinity stress under in-vitro conditions and for drought, in a rainout shelter. Nine different traits of root and shoot were studied in case of drought screening at rainout shelter and seven traits for salinity stress. 8-1-2 genotype was found to be more tolerant to drought and salinity stress. Utilitarian genetic variability can be used in different crop improvement programs and for studying the molecular basis of complex trait drought tolerance.
