Genomic Tools for Sweetpotato Improvement (GT4SP)
The more than 13.5 million metric tons (MT) of sweetpotato produced in Sub-Saharan Africa annually feed millions of people. However, the full potential of sweetpotato has yet to be recognized as large yield gaps (ca. 20 MT/ha) exist across rain-fed SSA due to a wide range of biotic and abiotic constraints, and the lack of productive, resilient, consumer-preferred varieties.
This project will develop modern genomic, genetic, and bioinformatics tools to facilitate crop improvement and improve genetic gains in sweetpotato, an important food security and cash crop with highly recognized potential to alleviate hunger, vitamin A deficiency, and poverty in Sub-Saharan Africa (SSA), and predominantly grown in small plot holdings by poor women farmers.
Key Project Information
Our specific project objectives include: (i) development of genomic and genetic resources for sweetpotato improvement, including complete genome sequencing of NCNSP-0323 and NCNSP0306 two diploid lines expected to be suitable for use as the cultivated sweetpotato, I. batatas, reference genomes; (ii) development of a genome sequence-based molecular marker platform, with supporting bioinformatics, quantitative genetic methods, and analytical environment to facilitate modern sweetpotato breeding; (iii) multi-location phenotyping and marker-trait/validation studies in Uganda and Ghana; (iv) traditional and web-based training and capacity development efforts to incorporate MAB tools in sweetpotato breeding programs in Africa; and (v) effective project management and communication processes to ensure project success and dissemination of newly-developed resources to the wider sweetpotato and scientific communities.

Presentation: The Genomic Tools for Sweetpotato (GT4SP) Improvement Project - Building a modern breeding platform for sweetpotato improvementAccording to Craig Yencho’s presentation, if yield was improved in the sweetpotato growing areas, then the SPHI goal of 10 million by 2020 could be very realistic. Yencho presented the development ...
