Description:	Cassava (Manihot esculenta Crantz) belongs to the Euphorbiaceae plant family and is the only cultivated species of the genus. Eighty, out of 98 species of the genus, occurs in Brazil with distribution from the high lands of the central plateau of Brazil down to low lands in Amazon Basis and Northeast cost. This pool of genes from the diversity of the genus and the cultivated species is under intense studies in our laboratory to gain knowledge in the storage root potential for improving storage root quality associated to human health. Herbarium database, field trip expedition, DNA molecular markers technology, organization of a GENEBANK of clones, functional genomics technology, and development of new commercial products from the diversity has been carried out in the past six years. In the present document we are reporting the compiled information generated to illustrate our concept working-model to improve cassava. Results, so far, indicate that: 1. The Central plateau of Brazil presents the largest diversity in terms of number of species of the genus. 2. The low lands of Brazil, mainly Amazon Basis, present the largest diversity within the cultivated species. 3. The largest diversity within the cultivated species occurs in Amazon and Northeast of Brazil. 4. Unusual storage root traits have been identified in traditional clones. 5. Natural mutations have been described for the first time in cassava storage root. 6. Processing technologies have been approached to add value to the new cassava clones. In addition solid collaboration among Brazilian and USA institutions have created. 7. Functional genomics has been.
