ABID MAHMOOD1*, TAHIR LATIF AND M. ARIF KHAN2
Abstract
Salt tolerance of 4 commercial varieties and 17 breeding lines of Basmati rice (Oryza sativa L.) was assessed at early growth stage and at maturity in field plots artificially salinzed with NaCl and CaCl2 (1:1 by weight). The average electrical conductivity (EC) of soil was 1.2, 5.2 and 10.5 dS m-1. Forty-five days after sowing (20 days in saline or control conditions), shoot dry weights and sodium (Na) and potassium (K) contents of shoot were determined. At maturity, plant height, number of tillers per plant, panicle length, number of grains per panicle
