    Abstract
    The biofortification of cassava roots is one of the actual goals of genetic breeding, with the development of roots richer in carotenoids. In order to evaluate the natural genetic variation of cassava, this study analyzed 78 accessions from the Brazilian Amazon to verify the presence of single nucleotide polymorphism molecular markers in the phytoene synthase 2 gene associated with root color. From the sequencing of 294 bp containing part of the intron 2 and the exon 3 of the psy2 gene, three SNPs located in the coding region and the existence of eight haplotypes were identified...
