The study was conducted with an aim of developing a genotype independent efficient in vitro regeneration system for Canola (Brassica napus L.) that is not grown in Bangladesh. Plant regeneration was achieved through embryogenic callus production from hypocotyls and cotyledonary leaves with petioles. The optimum medium for callus induction was found with 0.5 mgl-1 2, 4- dichlorophenoxyacetic acid (2, 4-D). The best shooting medium for canola contained 3.0 mgl-1 benzyl amino purine (BAP), 0.1 mgl-1 naphtalene acetic acid (NAA), and 5.0 mgl-1 AgNO3 and produced maximum number of shoots when kinetin was used at a concentration of 0.5 mgl- 1. The profound positive effect of AgNO3 for Canola was found for callogenesis at 0.5 mgl-1 and for regeneration at 5.0 mgl-1. In vitro regenerated shoots of canola produced well developed root system on both the media with 2.5 mgl-1 NAA and 1.0 mgl-1 indole 3-butyric acid (IBA).
