Resumo: Molecular marks in the study of genetic distance between local goats groups of northwest: I. DNA samples. Abstract - The groups of Brazilians goat of northeast are originally of units brought at the time of settling and had differentiated geenotipicaly due to the geographic isolation. The genetic groups MoxotÛ and Canindé had been homologated as distinct breed. Even so some authors support, under the historical point of view, that goat presented only diverse color coat pattern, but with a same genetic origin. To investigate the diversity and genetic distance of similar coat color pattern, this work harvested samples of the main destined flocks the conservation of genetic resources of Researchs Institutes in the Cear·, PiauÌ and Bahia. The samples of blood are stored in the Embrapa Caprinos and Embrapa Meio-Norte laboratories. Until the moment, 100 samples of the MoxotÛ breed had been sampled, 32 of the CanindÈ breed, 152 of the Marota breed, 45 of Azul breed and the 37 of the Repartida one. The samples of blood of 25 MoxotÛ, 25 Marota breed and 10 Azul breed has been extracted by the protocol of phenol. The markers investigated until the moment are the INRA006, INRA172, CSRC 0247 and ILSTS011. The data observed had been not yet analyzed
