| Abstract: | The present investigation was undertaken to find out the best medium composition for medium-term preservation of disease free potato shoot tips in in vitro system.Thirteen potato genotypes and fourteen treatments were taken under consideration for the present experiment.Among fourteen treatments,mannitol and sorbitol containing media proved to be the best for medium-term preservation of potato shoot tips.High concentration of mannitol delayed root formation. |
