**Figure 7.** Flow cytometric analysis (left) and chromosome observation (right) of the seedlings obtained from reciprocal crosses between the diploid and the chimera of the Meiwa kumquat. Bars = 10 μm. **A**: Diploid (2n = 2x = 18). **B**: Triploid (2n = 3x = 27). **C**: Tetraploid (2n = 4x = 36). Arrows indicate the relative fluorescence of internal standard (the haploid pummelo (2n = x = 9, Yahata et al., [19])).

**Figure 8.** The triploid seedling obtained from the cross between the diploid and the chimera of the Meiwa kumquat (bar = 1 cm).
