A medium PM-2 containing 3 mg/l NAA and 0.25 mg/l 6-BAP has been standarized on which callus can be grown from different plant parts of dihaploid and tetraploid potato genotypes. However, callus could not be initiated from petals and androecium. Callus growth was significantly more in tetraploid genotypes in comparison with dihaploid genotypes.
