Continuous use of poor quality of irrigation has played an imperative role in the development of soil salinization in arid and semi-arid areas of the world. Besides the application of various physical, chemical and biological amendments, identification and cultivation of salts tolerant species is a promising solution to ensure crops cultivation under adverse saline condition. A lot of work has been documented so far, on reduction in growth and yield of different crops under salinity stress. However, identification and cultivation of salinity tolerant mango cultivars (cv’s.) have not received appreciable attention. Therefore, the current study was conducted to evaluate salinity tolerance among various mango cv’s. Eighteen months old seedlings of 8 mango cultivars (Langra, Anwar Retaul No. 12, Sufaid Chaunsa, Anwar Retaul, Aman Dusehri, Fajri, Samar Bahisht Chaunsa and Sindhri) grafted on desi (sucking type) mango irrigated with irrigation water under different levels of salinity (15, 30, 45, 60, 75 and 90mM NaCl). Tap water (TW) was used as control. Results confirmed that scion height, rootstock height, number of leaves, scion dry weight, rootstock fresh and dry weighs were significantly greater in cv. Langra as compared to Sindhri at 15, 30, 45, 60, 75 and 90 mM NaCl. A significant improvement of 0.78, 1.12, 1.17, 1.62, 2.20, 2.14 and 2.40-fold in chlorophyll content validated the salinity tolerant competency of Langra comparative to Sindhri at TW, 15, 30, 45, 60, 75 and 90 mM NaCl respectively. Less electrolyte leakage while significant improvement in relative water content, stomatal conductance and transpiration rate confirmed that cv. Langra has more tolerant, while Sindhri is sensitive towards salinity stress.
