Allelism of the Fcu-1 and Foc genes conferring resistance to fusarium wilt in cucumber

The inheritance of resistance to Fusarium oxysporum f.sp. cucumerinum race 1 was determined in the cucumber cv. WIS-248 by analyzing segregation of F sub(1), F sub(2), and BC populations of crosses with the susceptible cv. Straight-8. Resistance was conferred by a single dominant gene. In an allelis...

Zusammenfassung:	The inheritance of resistance to Fusarium oxysporum f.sp. cucumerinum race 1 was determined in the cucumber cv. WIS-248 by analyzing segregation of F sub(1), F sub(2), and BC populations of crosses with the susceptible cv. Straight-8. Resistance was conferred by a single dominant gene. In an allelism test, it was proven that the Fcu-1 gene, which confers resistance to F. oxysporum f.sp. cucumerinum races 1 and 2 in cucumber cv. SMR-18 and the Foc gene, which confers resistance to F. oxysporum f.sp. cucumerinum race 2 in cucumber cv. WIS-248, are indistinguishable.
