Groundnut seed systems in Senegal and NigerJNdjeungaauthorB RNtareauthorThe informal seed systems in Senegal and Niger are described. These systems still remain the main seed sources for almost all small-scale holder farmers in both countries. The systems perform fairly well at supplying seeds to end-users, distributing seeds at relatively low cost, and maintaining acceptable levels of seed viability and health. A tabulated list of groundnut varieties released in Niger and Senegal is provided. The trends in commercialized production of groundnut seeds in Niger and Senegal are presented.Groundnut2001International Crops Research Institute for the Semi-Arid TropicsArticle
