**10. On-farm management of local seed diversity**

In Nigeria, in spite of the event of the formal certified seed sector, many rural farmers continue to use traditional seeds or other planting materials to meet their seed need [55]. They have their own method of selection and conservation of seeds. This method varies slightly from one crop to another. Indeed, seeds are collected at maturity on apparent healthy plants and saved from season to season by individual farmers. As with selection, storage and conservation methods varied with crops. As such, seeds were stored either in packages and suspended at kitchen roofs (in the case of maize and cowpea, for example, in Yorubaland in Nigeria) or in grain and bottled (case of peppers, tomatoes, etc.). Yet, there can also be significant amounts of exchange between neighbors and relatives. They are also purchased when necessary. On-farm management of local seed diversity is predominant in the Nigeria seed sector since conversely to the cotton culture; no organized provision system exists for food crops.
