The index of coincidence was obtained using the ratio between twice the number of progenies in which both selection indexes coincide and the sum of the total number of progenies containing the selection index A plus the total number of progenies containing the selection index B (Pedrozo, Benites, Barbosa, Resende, & Silva, 2009).
