A New Spray Chrysanthemum Cultivar, “Ilweol” with Anemone Type and Yellow Color

A new chrysanthemum (Dendranthema grandiflorum) cultivar “Ilweol” was released by National Horticultural Research Institute (NHRI), Rural Development Administration (RDA), in 2001. The cross was made in 1998 between “Soneo”, an anemone type cultivar bred earlier in NHRI, and “96B1-159”, a breeding line of NHRI. The characteristics are investigated from 1999 to 2001 for the evaluation and selection of this variety, including shading culture in summer and retarding culture in autumn. The natural flowering time of “Ilweol” is early November, but year-round flowering is possible by shading and lighting. It has anemone type flowers, yellow petals and bright red brown flower center. The diameters of flower and flower center are 4.2, 2.3 cm, respectively. The number of the petals is 30 and the days to flower from short day treatment is about 65 in spring and summer season. This variety has strong plant dormancy in late autumn.
