Abstract

The ability to introduce favorable alleles for multiple genes from a donor breed into a commercial breed through a backcross program of limited size was evaluated. The effects of fraction selected, marker interval, and number of quantitative trait loci were considered. Informative flanking markers were used to select progeny with the largest expected number of recipient QTL alleles for 5 generations. With
