Solanum tuberosum is the third world ranking species in terms of yield and consumption, after rice and wheat. Ipomoea batatas is the seventh world ranking production vegetable and provides food for over 68% of population. They are growing and fructification in hard climate conditions with arid soils or desert (sweet potato), and have important role in biodiversity through culture conditions adaptability, plant diseases and pathogens resistance (potato). Despite all these advantages, infections that are combined on those species reduce production capacity up to 90% in both species and this factor can be controlled to some extent by using micropropagation techniques and thermotherapy. Scientific papers, treaties and communications were studied in order to gather the most relevant dates regarding micropro-pagation of those two species. The high genetic variability this two species have makes it difficult to standardize micro-propagation protocols, such as disinfection, phytohormones combinations and other techniques used in micropro-pagation regarding the devirosation of the plant material and the production of virus free material. Solanum tuberosum and Ipomoea batatas are two species that are two of the most cultivated worldwide, in poor or in development countries based on their nutritional values and their economic importance, scientists and breeders are focusing on biotechnologies to produce new varieties with high production capacity and promising resistance to pest, diseases and viruses.
