A study aimed at understanding the different methods of storage and conservation of cereal seeds was carried out in the locality of Gazawa, region of Far-North/Cameroon. The objective was to determine the local conservation knowledge of farmers in order to preserve the diversity of production plant material and promote sustainable integrated management of plant genetic resources. Based on a methodological survey, question and answers based on target sample of fifty individual persons. It follows that in total 6 varieties of maize (CMS-9015, CMS-8806, CMS-8501, CMS-8704, TZEE-W and EVDT) and 6 varieties of sorghum (CS-54, CS -61, CS-95, Damougari, S-35 and Zouaye) are popularized, maintained. The EVDT varieties of corn and CS-95, CS-61, Damougari of sorghum are kept ex-situ in cold rooms or conservation structures. Optimal dehydration method, warehouse maintenance applied and in conservation structures help to maintain seeds quality and varietal diversity. The only variety of rice recorded was Nerica 3 and 25 collections of pennicilary millet from the Far-North and North of Cameroon, ICRISAT and INERA are being popularized. The local varieties Sectaire (22.85 %), Dadoudou (11.42 %), Farigawa, Salié, Viri by 8.57 %, local white maize (5.71 %) and Panar (2.85 %) are the most appreciated and cultivated by farmers for their organoleptic properties, their nutritional values and their productivity. The local seeds of the farmers are kept with the corn cobs enclosed in the husks, the panicles covered with the powder of the glumes hanging in sheds.
