Description Due to its xerophytic characteristics pomegranate is a suitable crop for dryland regions characterized by
water scarcity, salinity and nutrients deficiency. India is the world leader in pomegranate production.
Cultivation of horticultural crops on highly deteriorated salt affected soils irrigated with saline water may
improve economic conditions of the farmers. Keeping these facts in view, an experiment was conducted to
evaluate different pomegranate genotypes, collected from Rajasthan, India for their salt tolerance potential.
Survey of pomegranate growing areas of Rajasthan was conducted during August, 2015. Hardwood cuttings
(15-20 cm length) of 18 unknown and 2 known genotypes were collected and grown in normal (ECe~2.4 dS
m-1) and saline soils (ECe ~8, 12 and 16 dS m-1). Four months after planting, different growth and
physiological parameters were recorded. Survival of cuttings significantly decreased with increasing salinity
with mean survival of about 3% at 8 dS m-1, 1.33% at 12 dS m-1 and 0.67% at 16 dS m1 indicating genotypic
differences for salt tolerance. The lowest (66.67 %) and the highest (100 %) survival of cuttings under control
conditions were recorded in Bhagwa and Rajasmand 2 genotypes, respectively. Genotypes Jaipur-2, Jaipur-3,
Ajmer-1, Ajmer-2, Rajasmand-3, Rajasmand-4, Udaipur-1, Udaipur-2, Ganesh and Bhagwa survived up to
salinity level of 8 dS m1. However, only 5 of these genotypes (Jaipur-2, Jaipur-3, Rajasmand-3, Udaipur-1 and
Udaipur-2) could tolerate salinity level of 12 dS m-1 and only 2 (Udaipur-1 and Rajasmand-3) could survive at
the highest salinity (16 dS m-1) level. On the basis of survival and plant growth, these genotypes are under
evaluation in naturally saline soils (ECe upto 15.61 dS m-1) at Nain Experimental Farm, Panipat. After five
months of planting in the field, the maximum plant height (105.45 cm) was observed in genotype Jaipur 2 followed by 97.85 cm in Udaipur 1 and 93.7 cm in Ajmer 1. The highest average numbers of branches (16)
were recorded in Ajmer 2 followed by 15 in Bhagwa and 13.67 in Udaipur 3. The maximum stem diameter
(2.02 cm) was recorded in Udaipur 2 followed by Ajmer 2 (1.7cm) and Rajasmand 4 (1.65 cm). Plant spread
was the maximum (90.35 cm) in Ajmer 2 followed by in Udaipur 1 (89.53 cm) and Bhagwa (84.53 cm). It was
found that Ajmer 2, Udaipur 1 and Bhagwa genotypes performed better under saline conditions.
