Quality seed is the starting point for any successful agricultural venture and a functioning sweetpotato seed system contributes to food security and income generation. The transition between breeder and pre-basic (i.e. first generation or foundation) seed production is a major bottleneck in the functioning of an efficient seed system for sweetpotato. This brief, describes the efforts of SASHA to strengthen technical, financial and institutional capacities for the sustainable production of pre-basic sweetpotato seed in 11 sub-Saharan African countries. This is via developing and testing different seed system technologies to increase the multiplication rate for sweetpotato and improve the supply of quality, early generation seed. These systems are projected to be self-sustaining by channelling revenue from seed sales back into future seed production.
