**6. Conclusion**

Potato is ranked as the fourth most important staple food crop and the number one non-grain food commodity as per the Food and Agriculture Organization of the United Nations (FAO) (2018). It has increasingly become an international commodity cultivated across the world. In Central Africa, Potato is cultivated in mountainous regions where climatic conditions are favourable. However, its productivity is still very low (510 tons/ha) due to the use of degenerated potato seeds and poor agricultural practices by farmers. Limited use of quality seed potatoes, by less than 4% of farmers is due to lack of appropriate facilities, in vitro laboratory, which cannot be affordable to potato seed producers. So, in this chapter different techniques of cuttings that could be applicable to farmers are developed by using meristematic tissues which are considered free diseases and restore the genetic potentiality of cultivated varieties.

It was proved that the use of good quality seeds increased the productivity of potatoes by more than 35%. In order to make them available during cropping seasons, it would be necessary to take into account the variable dormancy of the different varieties and to establish an appropriate agricultural calendar the potato seed production, which examples have been given in this chapter.
