Abstract: In callus induction of Gossypium hirsutum L.cv.coker 201, IAA and 2, 4-D showed positive effect and KT showed negative effect, while negative effect was shown with the three hormones in suspensions.The best enzymatic combination in protoplast isolation from embryogenetic suspensions was 3% cellulase(Onozuka R10)+1.5%pectinase, and the best hormone combination in protoplast culture was IAA 0.5mg/L+KT 0.1mg/L. Appropriately increasing protoplast density benefited protoplast culture. Light and temprature affected the protoplast culture.Protoplast-derived calli growed rapidly in suspension culture medium without any hormone and regenerated plants through differentiation culture.

Key words: Gossypium hirsutum L, Protoplast culture, Plant regeneration
