The Grain Research Program (GRP) is a newly established programme that was developed by a team of multidisciplinary grain researchers from different institutes and programmes at FABI and elsewhere in South Africa. The GRP was formed to engage directly with grain stakeholders to initiate research that will support this sector by identifying future challenges to the industry and exploring solutions to these challenges. To its stakeholders in agriculture, the GRP also provides extension and disease/pest diagnostic services. In other words, the vision of the GRP is to contribute to South Africa’s food security and bioeconomy by conducting basic and solution-oriented research, which in turn forms a base for further innovation in the South African agricultural sector. 

Other FABI programmes in the grain health domain:

Applied Mycology

Cereal Foliar Pathogen Research

DSI-NRF Centre of Excellence in Plant Health Biotechnology

Crop Floral Biology And Environments

Molecular Plant Physiology

Molecular Plant-Pathogen Interactions

Potato Pathology Programme

Seed Science
