Abstract
The mode of inheritance of resistance to Fusarium oxysporum f.sp. cucu merinum races 1 and 2 in Wisconsin-2757 (WI-2757), a gynoecious cucumb er (Cucumis sativus L.), was determined by analysing segregation of F- 1, F-2 and BC1 populations of crosses with susceptible cultivar Straig ht-8. Resistance to either race 1 or race 2 in WI-2757 was conferred b y a single dominant gene. In allelism tests, resistance to either race in WI-2757 was determined by the gene Fcu-1, which also confers resis tance in line SMR-18.
