WHAT IS CBRRR?
The Common Bean Root Rot Resistance project (CBRRR) is researching the spread and effects of root rot disease complexes in Uganda. Root rots are one of the main threats to common bean production in sub-Saharan Africa, causing estimated losses of 221,000 metric tons a year. CBRRR is therefore working to determine the prevalence and incidence of these diseases and develop root rot resistant varieties of common bean that can be used by smallholder farmers across East and Central Africa.
WHAT ARE ITS AIMS?
The main objectives of this project are:
- To collect S. rolfsii and Pythium spp. isolates and map their distribution across the different agro-ecologies in Uganda
- To conduct phenotypic and genotypic characterisation of S. rolfsii and Pythium spp. isolates
- To develop molecular diagnostic tools for the detection of S. rolfsii
- To screen breeding lines and local germplasm for resistance to S. rolfsii and Pythium spp. root rots
- To identify genetic markers associated with Sclerotium root rot resistance genes
WHO IS DELIVERING CBRRR?
- National Crops Resources Research Institute (NaCRRI)
- International Center for Tropical Agriculture (CIAT)
