Tropical legume project impact on groundnut improvement research outputs in NigeriaC AEchekwuauthorUAlhassanauthorS GMohammedauthorB NMotagiauthorH AAjeigbeauthorBAhmedauthorM BVabiauthorGroundnut is an important component of the farming systems in the dry savannas of Nigeria. It is planted on 34% of cultivated area and contributes to 54% of household cash in the country. Groundnut production in Nigeria has suffered from major setbacks; fungal and bacteria diseases, aflatoxin contamination and weak seed system. However, considerable progress had been made by IAR, ICRISAT and several partners to overcome these setbacks through the development and deployment of improved groundnut varieties and associated crop management systems. Earlier released Rosette resistant varieties, RMP12 (SAMNUT10) and RMP91 (SAMNUT11), were late maturing varieties. With climate change resulting in shortened growing season, the need for early-maturing, disease- and drought-tolerant varieties became urgent. Collaborative efforts of several partners resulted in the official registration and release of medium duration: SAMNUT21 (UGA2), SAMNUT22 (M 572, 80I), and early-maturing varieties SAMNUT23 (ICGV-IS 96894) in 2001. With the arrival on the scene of the Tropical Legume Project (TL), along with the excellent research and development support, Samnut-24 and Samnut-25 and Samnut-26, were released. These varieties are part of the achievements from TL activities during 2012-13 and are our pride. These varieties are making a difference in the lives of farmers, improved the sustainability of the systems and also increased the cultivation of groundnut even in the dry season. TL project in Nigeria took the unique opportunity to partner with USAID-Groundnut up-scalling project to build capacity of farmers and awareness of improved production technologies and make seeds of improved varieties available.Crop ImprovementNigeriaGroundnut2017-02Conference or Workshop Item
