Targeting three large-effect QTL (located on the chromosome arm 3BL, 5DS and 2DL, respectively), we investigated the feasibility of enhancing FCR resistance by gene pyramiding. Significant effects were detected for each of the three QTL in both populations assessed. Lines with any combination of two resistant alleles gave significantly better resistance than those with a single resistant allele only and those without any allele, and lines possessing all three resistant alleles showed the best resistance. These results demonstrated that gene pyramiding can be an effective approach in improving FCR resistance. Those lines with resistant alleles from all three QTL could be valuable genetic stocks for breeding programs.
