摘要：

The inheritance of the resistance to Fusarium oxysporum f. sp. melonis (F.o.m.) races 0 and 2 in 'Tortuga', a Spanish cantalupensis accession, was studied from crosses of 'Tortuga' by the susceptible line 'Piel de Sapo' and the resistant one 'Charentais-Fom1' that carries the resistance gene Fom-1. The segregation patterns observed in the F-2 ('Tortuga' x 'Piel de Sapo') and the backcross ('Piel de Sapo' x ('Tortuga' x 'Piel de Sapo') populations, suggest that resistance of 'Tortuga' to races 0 and 2 of F.o.m. is conferred by two independent genes: one dominant and the other recessive. In the F2 derived from the cross between accessions 'Tortuga' and 'Charentais-Fom1', the lack of susceptible plants indicated that the two accessions are carrying the same resistance gene (Fom-1). The analysis of 158 F-2 plants ('Tortuga' x 'Piel de Sapo') with a Cleaved Amplified Polymorphic Sequence marker 618-CAPS, tightly linked to Fom-1 (0.9 cM), confirmed that 'Tortuga' also carries a recessive gene, that we propose to symbolize by fom-4.
