More than 1000 sweet potato varieties are grown by smallholders in Papua New Guinea. This is a pardoxical situation for a plant that is propagated vegetatively and was imported from Latin America. Where did this remarkable diversity come from and how do producers make use of it? Researchers from CIRAD and CEFE recently showed that most of the varieties were bred locally from plants resulting from sexual recombination that appeared spontaneously in plots. This is a dynamic process that enables producers to adapt to change, and constitutes an asset for the future.
