摘要
Ninety-three recombinant inbred lines were produced by single-seed descent from reciprocal crosses of Cucumis melo 'PMAR No. 5' and 'Harukei No. 3'. Using these lines, resistance to race 1 of powdery mildew, cotton aphid resistance and flesh colour were studied. Resistance of 'PMAR No. 5' to the powdery mildew fungus appeared to be conferred by two dominant and independent genes, because F, plants were moderately resistant and the observed segregation ratio of the resistant, moderately resistant and susceptible lines was 42:31:19. Genetic analysis revealed that cotton aphid resistance and flesh colour were controlled by single dominant genes. The usefulness of recombinant inbred lines was discussed.
