One of the objectives of the SASHA project is to strengthen technical, financial and institutional capacities for the sustainable production of pre-basic sweetpotato seed in 11 sub-Saharan African countries. This flyer outlines the schematic of sweetpotato seed system and the progress made from June 2014 to July 2015 towards achieving this objective. It specifically summarizes work in developing and testing different seed system technologies to increase the multiplication rate for sweetpotato and improve the supply of quality, early generation seed; and exploring innovative partnership business models between public research programmes and private entities that may contribute to developing commercially viable seed systems.
