in order to investigate effective morpho-physiological traits related to salinity resistance, and their relationship with grain yield as well as study of salinity tolerance and susceptibility indices in 169 barley recombinant inbred lines, a  population of barley derived from a cross between arigashar and igri, this experiments were carried out using alpha lattice design with two replications d...

Selecting and cultivating the crops/varieties that can tolerate water salinity is potentially animportant strategy to save fresh water resources and maximize the crop yield in salt affected areas.To evaluate the responses of 36 sorghum lines and cultivars to salinity stress, two fieldexperiments were conducted in non-stress (EC=2 dS/m) and salinity stress conditions (EC=12dS/m) using randomized...
