The paper aimed to present the protocol for obtaining vitro tubers or also called micro tubers from two varieties of potato: Christian with regular colour of flesh and Salad Blue with purple flesh. This protocol is based on micropropagation technique which combine an agar-solidified phase succeeded by a liquid phase in the same vessel in aseptic conditions. Using the double-phase technique gave the opportunity to reduce the costs generated by the utilities.
