Globally, there is great interest in applying new genomic technologies to accelerate genetic gains in developing country breeding programs. However, these methods have not been adopted in developing country level National Agricultural Research Institutes (NARI) due a mismatch between available genomic selection approaches and the existing operations of NARI breeding programs. Globally, there is great interest in applying new genomic technologies to accelerate genetic gains in developing country breeding programs. However, these methods have not been adopted in developing country level National Agricultural Research Institutes (NARI) due a mismatch between available genomic selection approaches and the existing operations of NARI breeding programs.
This project aims to develop genomic approaches from within a NARI breeding program to reduce barriers for adoption. Specifically, these improved genomics selection approaches will be deployed to address several key constraints for dual-purpose sorghums used by smallholders in Haiti. The targets will be improving grain yield while maintaining forage yield and quality, improving tolerance to low/high pH soils, and improving tolerance to post-emergence and post-flowering water limitation.

This project began an Associate Award from USAID, the Feed the Future Innovatin Lab for Genomics-Assisted Sorghum Breeding in 2016 (AID-OAA-LA-16-00003) led by Dr. Edward Buckler at Cornell University, Dr. Gael Pressoir at Université Quisqueya, and Dr. Geoffrey Morris at Kansas State University. After much success, the Associate Award ended and this project continues the work and research. This project ensures that innovations on aphid and drought resilient varieties by the Université Quisqueya sorghum program will lead to durable solutions for smallholder farmers and downstream stakeholders in Haiti. Further, technology will be developmed to facilitate the diffusion of the technology from Haiti to other smallholder-serving breeding programs in Latin America and beyond. By designing genomics-assisted breeding approaches in a National Agricultural Research Institute (NARI), the resulting technology will be better suited for adoption by other NARIs globally. The tools and resources developed in this project will facilitate adoption of genomics-assisted breeding by partner programs in West and East Africa and will be diffused globally via breeding informatics initiatives (GOBII and BMS).
The project is developing new aphid resistance marker technology, to further reduce aphid damage and mitigate the possibility that the RMES1 gene is overcome by the aphid. Genotype and phenotype data collection for aphid resistance in the Université Quisqueya program has been completed, and initial mapping of new aphid-resistance loci is underway. Similarly, new drought tolerance loci have been identified based on field phenotyping of drought response in the Université Quisqueya program. Using the same aphid and drought phenotype data, researchers are testing hypotheses on potential tradeoffs and limitations of the current aphid and drought resilience traits used by Université Quisqueya to develop breeding strategies that circumvent these issues.
