Fifty-four wheat genotypes from different origins and eras were evaluated based on the use of RAPD markers. Once genetic variability is detected among breeding materials, appropriate crosses can be done, sppeding up breeding processe and decreasing costs. Of 100 primers screened, 20 produced scorable bands, which generated 91 bands. The average genetic similatiry value among all genotype pairs was 0.88, showing large genetic relationships in the wheat germplasm evaluated. The dendogram clustered the genotypes into mine groups and showed efficiency in identifying genetic variability. agenetic similarity apolymorphism aTrigo aTriticum Aestivum aMolecular markers aVariabilidade genética1 aBARBOSA NETO, J.
