Abstract
Six Brassica napus genotypes Salam, Altex, Ganyou-5, PR-7, Marnoo, NARC-82, and four Brassica Compestris genotypes Desi, Tobin, Torch and Span were screened for salt tolerance under glasshouse conditions at maturity stages. Two levels of salinity i.e; 7.5 and 15 dS.m -1 were induced in soil under test along with control (EC 1.2 dS.m -1 ). Root zone salinity reduced plant height, stem diameter, biological and grain yield significantly over control. Cumulative varietal means showed that relative yield was higher in NARC-82 and Desi as compared with other cultivars. K+ /Na+ ratio decreased with increasing root zone salinity. Relatively, salt tolerant cultivars appeared to exclude Na+ and maintain K+ and K+ /Na+ ratio higher than the sensitive cultivars.
