The main
advantages of MABC are (1) efficient foreground selection
for the target locus, (2) efficient background selection for
the recurrent parent genome, (3) minimization of linkage
drag surrounding the locus being introgressed, and (4)
rapid breeding of new genotypes with favorable traits. The
effectiveness of MABC depends on the availability of closely
linked markers and/or franking markers for the target locus,
the size of the population, the number of backcrosses,
and the position and number of markers for background
selection
