Abstract. Fertile transgenic sweet pepper (Capsicum annuum var. grossum) plants were regenerated at relatively high rate from various explants that were cocultivated with Agrobacterium tumefaciens strain GV3111-SE harbouring a plasmid that contains the cucumber mosaic virus coat protein (CMV-CP) gene. The rate of plant regeneration was found to depend on the types of explant cultured and the media used. Young leaves were most effective for bud induction and subsequent plant elongation while hypocotyls were the most inefficient. Southern analysis of DNA isolated from putative transgenic plants revealed that 3 out of 5 R1 plant lines reacted positively with the CMV-CP gene. Western blot analysis of CMV-CP containing R1 plants showed that two of them accumulated significant levels of the foreign gene product while the other two expressed it only to low levels. Thus, like many other dicotyledonous plant species, sweet pepper can be transformed by A. tumefaciens and regenerated into healthy, fertile plants that express foreign genes.
