The first separation of cassava accessions into
three groups based on the DAPC of SNP markers indicated
a hierarchical level for use in targeting possible
contrasting intersections based on molecular information.
Therefore, considering the groups that are formed
by DAPC, the best crosses among the CMD resistance
sources and the cassava elite varieties that are most frequently
planted in Brazil were selected considering the
two most contrasting combinations regarding genomic
relatedness (Table 4).
