Abstract: The invention a novel and efficient method for protoplast culture comprising the steps of isolating the protoplasts from a cell suspension, mixing the protoplasts with equal volumes of alginate solution, placing 40-50 &mgr;l of CaCl2 solution on a glass microslide, placing a mixture of protoplasts and alginate solution on the glass microslide and immediately covering by a glass coverglass, adding CaCl2 solution from the sides of coverglass, sliding down the coverglass towards one side and placing it in a petridish containing protoplast culture medium, sealing the petridishes, incubating it and transferring the extra thin alginate layer with celled colonies to regeneration medium for development of culture.
