Development of low cost technology for in vitro mass multiplication of potato (Solanum tuberosum L.)

Production of potato is constrained by lack of disease-free planting materials. This can be circumvented through tissue culture but the technology is costly limiting its adoption. As composition of culture medium used for shoot regeneration has a great influence on cost and there is a potential for use of locally available low cost resources as alternatives to the conventional costly laboratory resources. There is...
