High-resolution mapping of resistance to cassava mosaic geminiviruses in cassava using genotyping-by-sequencing and its implications for breeding

Cassava mosaic disease is the most important disease of cassava in Africa and the Indian sub-continent

Abstract

Highlights from this paper:

  • Cassava mosaic disease seriously affects production of cassava in Africa and India.

  • Singe-gene resistance from related landraces is extensively deployed in breeding.

  • High-resolution mapping using genotyping-by-sequencing identifies a single locus.

  • Previously published resistance-linked markers co-locate with identified locus.

  • This suggests a very narrow genetic of the resistance in the crop鈥檚 genepool.

This work is part of the 鈥淣ext Generation Cassava Breeding Project鈥� which is supported by the UK Department for International Development, in partnership with the Bill & Melinda Gates Foundation.
