Germplasm Enhancement for Increasing Groundnut Productivity and Production in West and Central Africa uri icon

abstract

  • West and Central Africa (WCA) account for almost 70% of groundnut production in Africa playing an important roleto farmers? livelihood and significantly contributes to the export sector of the countries in the region. However, theproductivity in the region is limited due to many factors including biotic and abiotic constraints. The gap betweenpotential and realized yield is large in subsistence farming. To address these issues, ICRISAT has been workingwith 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 nationalprograms in WCA for genetic enhancement of groundnut. Based on the NPT and PVS trials, the national programsin Niger released four varieties (RRB, ICG 9346, J11 and Fleur 11). In Nigeria, three short-duration, rosette resistantvarieties (Samnut-24, Samnut-25 and Samnut-26) were released. In Mali, eight varieties including ICGV 86015 andICGV 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, shortduration, seed size, suitability for home consumption, seed color and market demand and had yield advantage ofup to 42% over the local varieties grown by farmers. The current efforts to deploy modern breeding approachesand tools to enhance genetic gains are discussed
