\textbf{Abstract}
\begin{abstract}
\normalsize{
Plant production is limited by biotic and abiotic stresses in many regions of the world, which fact cause a great gap between actual yield and potential yield. In this case, the ability of a plant to withstand stress is an important factor to determine yield. Salt and drought are among the most challenging environmental constraints to crop. The use of salt"=resistant genotypes of plant is the best way to obtain the optimal yield on saline soils. Oilseed rape, a major crop in terms of oilseed production in many parts of Iran, with a high salinity threshold level (10 dS m$^{-1}$) is one of crops in the tolerant category. Therefore, this crop has the potential to cultivate in saline areas. Identification and selection of superior genotypes is the first step toward developing salt"=resistant plants. This requires enough intraspecific variation and screening germplasm based on appropriate criteria. Greenhouse experiment was conducted to study the response of different oilseed rape varieties to salt stress and determine selection criteria of salt"=resistant varieties. Nineteen salt"=tolerant and salt"=sensitive oilseed rape varieties were grown at two environmental conditions including normal and saline soils (2 and 16 dS m$^{-1}$, respectively) in a factorial, randomised complete block design with three replications. Sampling was performed at the end of rosette stage. In comparison with normal conditions, salt stress treatment showed significantly lower biomass production, but had little or no effects on plant pigments. However, salt stress reduced chlorophyll a, b, antocianine and flavonoid contents, but increased carotenoid and proline content. Varieties had significant effect on proline and pigments. There was no significant correlation between these traits and biomass. Generally it can be said that proline and pigments in canola leaves aren't suitable as a screening index for salt stress because they depend on the genotypes.}
