Twenty citrus rootstocks were screened in a pot study for their salinity tolerance through varying chloride levels (0, 300, 600 and 900 ppm Cl− through NaCl) in irrigation water. The susceptibility/tolerance of the rootstocks to salinity was evaluated on the basis of response to plant height, number of healthy leaves/plant and root volume/plant, days taken for appearance of leaf chloride toxicity symptoms substantiated by water soluble Cl− content of soil. The rootstocks were divided in four major groups on the basis of their salt tolerance viz., (
