Abstract
A solution culture experiment was carried out to screen wheat genotypes against salinity. The experiment was conducted in a greenhouse by growing forty wheat genotypes in- 200 L capacity tubs containing Hoagland solution. There were three treatments viz. control (non-saline), 100 and 200 mol m" NaCI arranged according to completely randomized design with five replications. Salinity was imposed gradually and plants were harvested forty days after stress. An increase in salinity reduced the vegetative growth significantly. Genotype BWN-75 proved to be tolerant at both the stress levels due to exclusion of Na' and Cl', and tolerance of PARC-N1, PARCN2 and Bakhtawar could be attributed to better management of these ions, while that ofPARC-N3 due to both the mechanisms . Key words: salinity, screening wheat genotypes, solution culture
