SASHA Brief 03: Weevil resistant sweetpotato through biotechnology

Unfortunately, weevils continue every year to damage about a quarter of the sweetpotato harvest in countries like Uganda and alter the quality and safety of storage roots. A long effort to express Cry proteins that would kill weevil larvae in the infected storage root has not resulted in obtaining fully …

Poster 6: Breeder’s role in accelerating orange fleshed sweetpotato (OFSP) value chain development for nutrition and livelihoods in Africa

Being the starting point of the value chain, plant breeding carries a great responsibility. In addition to being a reliable food security crop, orange-fleshed sweet potato (OFSP) varieties are rich in beta-carotene; hence reduce vitamin A deficiency (VAD) in women and young children and is increasingly being recognized and expanding …

SASHA Brief 2016: Weevil resistant sweetpotato through biotechnology

Weevils damage about a quarter of the sweetpotato harvest in Uganda and induce the accumulation of toxic compounds in the healthy-looking parts of damaged storage roots. We have introduced new genes that produce anti-weevil proteins in the sweetpotato storage root through biotechnology. We may have found few with some resistance …

SASHA Brief 2011: Safety of weevil resistant sweetpotato varieties

Genetically modified (GM) crops contain traits that have been introduced by the tools of modern biotechnology. Their novelty has prompted comprehensive assessment of their human and environmental safety. With conventional breeding, thousands of genes are shuffled and recombined to obtain a desired trait. In comparison, modern biotechnology adds as little …
