West and Central Africa (WCA) account for almost 70% of groundnut production in Africa playing an important role to farmers’ livelihood and significantly contributes to the export sector of the countries in the region. However, the productivity in the region is limited due to many factors including biotic and abiotic constraints. The gap between potential and realized yield is large in subsistence farming. To address these issues, ICRISAT has been working with national partners in the region to improve productivity of groundnut with the Tropical Legumes project support. ICRISAT has supplied more than 2,500 trait-specific advanced breeding lines (resistance to foliar diseases, rosette, aflatoxin contamination, early and medium maturing, confectionery types and tolerant to drought) to the national programs in WCA for genetic enhancement of groundnut. Based on the NPT and PVS trials, the national programs in Niger released four varieties (RRB, ICG 9346, J11 and Fleur 11). In Nigeria, three short-duration, rosette resistant varieties (Samnut-24, Samnut-25 and Samnut-26) were released. In Mali, eight varieties including ICGV 86015 and ICGV 86124 were selected by farmers. While six and four varieties were released in Senegal and Ghana respectively. Most of these varieties were preferred by farmers for their high yield, disease resistance, drought tolerance, short duration, seed size, suitability for home consumption, seed color and market demand and had yield advantage of up to 42% over the local varieties grown by farmers. The current efforts to deploy modern breeding approaches and tools to enhance genetic gains are discussed.
