A laboratory experiment was conducted at Agronomy Department Laboratory of Seed Testing, Faculty of Agriculture, Mansoura University, Egypt, during December 2013 to study the effect of salinity concentrations on germination and seedlings parameters of some canola cultivars. The aim of this experiment was the study performance of three cultivars of canola i.e. Serw 4, Serw 6 and Serw 51 under different concentrations of salinity as NaCl i.e. 0.0 (control treatment), 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, and 1.8 %NaCl. The results indicated that Serw 6 cultivar exceeded the other studied cultivars in germination percentage, germination index, mean germination time and seedling vigor index. While, Serw 51 cultivar surpassed other studied cultivars in germination rate and speed germination index. As a result of increasing salinity levels from 0 (control) to 1.8% NaCl, studied germination parameters were significantly decreased. It could be concluded that for maximizing canola germination parameter, germinated seeds of Serw 6 or Serw 51 cultivars under control treatment (without salinity stress) or under conditions of 0.2% NaCl.
