Thro, Alberto Duarte Vilarinhos.  aThe valuation of biological diversity comprises two schools of thought, one utilitarian prizing the economic application of species and another prizing all biodiversity "per se". Genetic resources associate with economics while biodiversity, as non-resources, relies on philosophyand ethics to claim an existence value. Genetic resources are part of the biological diversity. A distinction between genetic resources and biodiversity is attempted in this paper through a review of the literature. Genetic resources of Manihot encompass those plants which associate with an economic activity, secure man's food needs or, however playing a minor role, accrue to the machinery of production. Thus regarded, only six species of Manihot (besides a hybrid) truly qualify as genetic resources.  abiodiversity  aplant breeding  aBiodiversidade  aForragem  aMandioca  aRecurso Genético  aEspecies alimentares  aFood species  aForaje crops  aMelhoramento genetico  aResistance to diseages  aResistencia a doencas1 aMENDES, R.
