GOBII is the first large-scale public-sector effort to systematically apply high-density genotypic information to the breeding of staple crops in the developing world. The project will develop and implement genomic data managment systems to enhance the capacity of public sector breeding programs to deliver increased rates of genetic gain. Initially the focus is on rice, wheat, maize, sorghum and chickpea in South Asia and Sub-Saharan Africa. The genomic data management systems will include databases, imputation systems, and decision support tools for plant breeders.
