Two independent set of experiments were conducted to screen 6 aonla cultivars (NA- 6, 7, 10, 18, chakaiya and anand 1) grown under different sodicity (control, 15, 30, 45, 60 ESP) and salinity (control, 5, 10, 15 dSm−1) levels. It was found that total chlorophyll content in the leaves of aonla cultivars decreased with increasing levels of sodicity and salinity. The chlorophyll content decreased maximum in NA-18 and Anand -1 followed by NA-10, whereas minimum in Chakaiya followed NA-7 and NA-6. Free proline and total free amino acid content in leaves increased in all cultivars with increasing sodicity/salinity levels. Maximum free proline and total free amino acids were recorded at 60.00 ESP and 15.00 dSm−1 ECe levels with minimum in control. Thus, based on biochemical analysis of leaves in different cultivars of aonla it is concluded that Chakaiya, NA-7 and NA-6 are successfully grown with 90 per cent survivility in sodic soil upto 30.0 ESP and saline soil upto 10.0 dSm−1 ECe.
