The intermediate resistance to black spot disease in the induced mutant, 'Gold Nijisseiki (γ-1-1)' was characterized by the appearance of necrotic symptoms only on young leaves treated with the host-specific toxin solution. To examine whether the intermediate resistance is genetically transmissible to the F1 seedlings from crosses between 'Gold Nijisseiki' and resistant or susceptible cultivars, the degree of resistance to the disease in the F1 seedlings was evaluated. For the identification of the seedlings with intermediate resistance in the F1 generation, the application of toxin solutions at 0.1 and 5 ppm to the disks from the 1st and 5th leaves was a reliable method. By using this method, many seedlings with intermediate resistance were identified in the F1 generation only when 'Gold Nijisseiki' was used as the parent. The segregation ratios in the F1 generation suggested that an incomplete recessive mutation was induced in the L-II cell layer of the mutant, 'Gold Nijisseiki'.
