The present research was undertaken to determine the incompatibility and to characterize its mechanisms in crossing of chrysanthemum cultivars. Seed set of crossing of ‘Monalisa’ and ‘Lineker White’ with the pollens from four other cultivars was higher than that of the other cultivars. Since the seed set ratio was over 5%, ‘Monalisa’ and ‘Lineker White’ were cross-compatible. The other cultivars showed only 1-3% seed set and ‘Vyking’ and ‘Jeongheungsung’ showed no seed set. According to microscopic observations, there were obvious incompatible characteristics after pollinations. Pollens swelled less because of low hydration and a small quantity of secretion was found on the stigmas. The stigmatic papillae were filled with callosic deposits. Pollens did not germinate properly and showed short and coiled or bulbous pollen tubes. Fluorescence microscopic observations showed that pollens were prevented from germination or stigmatic penetration. The data in the present study suggest that the crossed chrysanthemum cultivars have similar characteristics of sporophytic self-incompatibility.
