Abstract: Potato (Solanum tuberosum L.) is the most consumed food crop world-wide next to wheat and rice and potato production is rapidly increasing in Africa. Potato is a high potential food security crop in Ethiopia due to its high yield potential and nutritional quality tuber, short growing period and wider adaptability. Potato potentially grows in different corners of the country. In some parts of the country, potato is grown as a field crop whereas, in some other part, it is still grown as a garden crop. Despite the suitability of the agro-ecology for high quantity and quality potato production in the country, there are several constraints which drastically affect to the low production and productivity of potato crop under smallholder farmers condition. Therefore, the objective of this review study was to evaluate the current state of seed potato systems, seed potato husbandry, seed potato quality, seed potato storage and sourcing and marketing systems used by seed potato producers and potato utilization. The result of this review study showed that a number of factors are constraining the system. These consists lack of wide adaptive improved potato varieties, unavailability of improved storage facilities, the high cost of improved seed tuber, low price of produced tuber especially immediately during harvest are the major one. Based on the review information, it can be concluded that availing improved potato varieties, improved storage facility and creating better marketing opportunity are crucial to improve the seed potato systems.
