WHAT IS YANEB?
The Yam Nematodes Benin (YANEB) Project is working to strengthen yam production in Benin by identifying and using local and improved nematode-resistant varieties of yam. Benin is the fourth largest producer of yams globally, with 55% of its population depending on the crop for food and income security. Yam production in the country is currently declining due to several biotic and abiotic constraints, including plant-parasitic nematodes (PPN), which can cause 80–100% loss of tubers during storage. YANEB is building a greater understanding around PPN and developing nematode-resistant varieties of yam that will help increase food security and alleviate poverty across Benin.
WHAT ARE ITS AIMS?
The project has five main research aims:
- To assess the diversity, distribution, prevalence and incidence of PPN on yam throughout Benin with a focus on the Meloidogyne species and Scutellonema bradys
- To develop DNA-barcodes and high-throughput (multiplex) polymerase chain reaction (PCR) diagnostics for yam parasitic nematode (Meloidogyne and Scutellonema species) detection and identification
- To develop a pool of cultivars of high agronomic performance, resistance to yam parasitic nematodes and with good market value suitable for production in different conditions
- To produce clean planting material of the best cultivars for distribution to, and use by, farmers
- To strengthen the academic and/or technical capacities of students, NARS staff, technicians and yam farmers, and the research facilities of the Nematology Research Unit of the Faculty of Science and Technology of Dassa
