| Abstract:
Fusarium wilt, caused by Fusarium oxysporum f.sp. melonis, is a major disease of melons (Cucumis melo L.) worldwide. Resistance to races 0 and 2 is conferred by the dominant gene Fom-I. Molecular markers linked to Fom-I would be useful for marker-assisted selection in breeding for resistance. We have developed a backcross population from MR-1 and 'Ananas Yoqne'am' segregating for race 2 resistance. This population was screened for resistance to race 2 Fusarium wilt. Bulk segregant analysis was used to evaluate RAPD and AFLP markers potentially linked to Fom-I. | |
