Description The West and Central Africa region accounts for more than 70%
of the groundnut production in Africa. The crop is challenged by
various biotic and abiotic production constraints with drought
being the main abiotic constraint. ICRISAT has been working
with national breeding programs to develop improved groundnut
varieties. The approach used included identifying sources of
resistance, developing populations, evaluating in target environments
and releasing improved farmer preferred varieties for production.
The Tropical Legumes project initiated in 2007 has been
instrumental in strengthening the breeding program in the region.
Nine drought resistant/tolerant accessions were identified
from evaluation of the mini core collections, and these accessions
have been utilized as parents in crossing programs. Since
2007, ICRISAT distributed more than 1000 advanced breeding
lines to national programs. Farmer participatory variety selection
was found very useful for fast track release and adoption of improved
varieties. Twenty two varieties have been released/registered
across the region as a result of project efforts (4 in Ghana,
5 in Mali, 4 in Niger, 3 in Nigeria and 6 in Senegal). These varieties
are high yielding (yield advantage of >20%) with resistance
or tolerance to drought and major diseases. Currently, efforts
are underway to improve the efficiency of breeding programs
and to enhance genetic gain. These include designing product
pipelines based on traits of breeding interest; reducing generation
advancement process of breeding populations by growing
2 to 3 generations per year; integrating modern genomic tools;
digitizing data collection, analysis, management and sharing by
using BMS; and enhancing the skills of breeders and technicians.
