The mode of inheritance of resistance to Fusarium wilt in watermelon was determined by analyzing the segregation of F₁, F₂, F₃ progenies of crosses involving one susceptible (Mallali) and two resistant (Calhoun Gray, Summit) watermelon cultivars and backcross progenies to the susceptible parental cultivar. The ratios obtained indicate that resistance to race 1 of Fusarium oxysporum f. sp. niveum is controlled by a dominant gene.
