Lines with combined resistance to groundnut rosette disease, aphids, early and late leaf spots evaluated
for yield performance (2007)
During the 2006 crop season, a number of lines with desirable agronomic and quality characteristics (plant type,
pod shape, seed size and color) will be entered into preliminary on station trials to evaluate their yield
potential.

A report on groundnut participatory variety selection published (2007)
A draft synthesis report on the participatory variety selection (PVS) process was prepared, summarizing groundnut
variety selection trials conducted in Mali, Niger, Nigeria and Senegal. It documents the pathways to adoption of
improved groundnut varieties, the lessons learned and the perspectives for enhancing variety adoption. Surveys were
initiated in Dec 2006 for additional information to strengthen the report.

10-25 breeding lines with multiple resistance to groundnut rosette and foliar diseases made available on
request to NARS in WCA (2008)
Promising lines from the preliminary evaluation trials will be made available to NARS on request.

Activity 3B6.3: Conduct adoption and impact assessment of groundnut improvement research in WCA
Survey on the adoption and impact of improved groundnut varieties in four countries of WCA completed
(2008).
Surveys on the adoption of improved varieties in Mali, Niger and Nigeria were initiated in December 2006.

Output 3C: Crop management, Aspergillus flavus resistant groundnut varieties and post-harvest technologies
available to reduce aflatoxin contamination in food and feed products in the SAT of WCA
MTP Output Target 2006: Analysis of results from integrated aflatoxin management options trials undertaken
The main health related research area the WCA is pursuing concerns of aflatoxin contamination in groundnut.
Aflatoxin is carcinogenic and have a broad range of negative side effects on the immune system and growth and
development, especially of children. While it would be useful to understand the medical ramifications better, we
focus on options to reduce contamination of food and feed products. The field research conducted with farmers
confirms on-station results that aflatoxin contamination can be reduced significantly, down to levels that are safe for
consumption for young children. Monitoring of marketed products also showed that quality of available products
covers an enormous range, including samples that are safe for consumption. Producer and consumer awareness of
the existing problem, as well as options for its improvement are extremely low, but we are starting to tackle them.
Output target 3C1: Post-harvest technologies, and resistant groundnut varieties tested with producers, and
contamination levels monitored at the consumer end.
Research results from on-farm trails testing different options for reducing aflatoxin contamination in a range of
locations are all very positive, and showing the feasibility of control options. These results need to be published, and
undergo economic feasibility analysis.
