Callusogenesis and regeneration ability of cotyledon and hypocotyl explants from three Bulgarian pepper varieties in MS basal medium supplemented with l-3mg/l BAP. l.0mg/1 IAA and 0.5mg/l GA3 was studied. In the different variants of culture medium was registered high level of callusogenesis and organogenesis in both type of explants from the all varieties. The highest percentage of plant-regenerants is established in cotyledon explants (from 3.3 to 18.3) in variant 3 of the culture medium containing 3mg/l BA. In the process of micropropagation by stem explants of the same studied pepper varieties the addition of the vitamins C. B12. Casein hydrolysate and Ferulic acid had a stimulation effect on the plant growth in height and rooting. In result of anther cultivation from three pepper varieties and four breeding lines the highest percentage of embryo structure formation was registered in varieties Albena and Strjama (12.0 and 13.8 respectively). The Bulgarian peppers are recalcitrant and their in vitro answer is different depending from the explants type, genotype and the culture media composition
