Yams (Dioscorea sp., family Dioscoreacea) which are annual or perennial tuber-bearing and climbing plants are an important tuber crop in Anambra State of Nigeria. It is the only crop that is celebrated amongst the people. Over 600 species exit but only few are cultivated as food for man’s use. The yam belt stretches from the humid rainforest in the South to the Northern Guinea Savannah. About 85% of a yam tuber is edible, comprising of 15-23% starch, 1-2.5% protein, 0.05- 0.2% fat and so forth. Diverse species exit in the different communities as a result of farmers preferences. This very important food crop is faced with serious problems of loss of biodiversity and land degradation. Earlier survey carried out for collection and conservation of the diversities of this crop could not be sustained in the gene bank as a good number of them have gone on extinction. This necessitated the need for collaborative efforts by Global Crop Diversity Trust (GCDT) and National Root Crops Research Institute (NRCRI), Umudike to embark on a survey to collect all the landraces in the yam belt of Nigeria in which Anambra State falls, with the aim of identifying those that are extinct from the farming systems of the studied areas. Questionnaire with open-ended questions was used to gather information from the farmers. Information on farmer’s varietal, agronomic, culinary, socio-cultural and economic characteristics was discussed. Farmers in the studied areas reported that a total of five yam accessions have gone on extinction.
