Originally, most lilies for cut-flower were Asiatic and Oriental hybrids. These days, however, interspecific hybrid cultivars are reared worldwide and customers expect various flower types and colors. ‘Cream Bell’ cultivar is an interspecific OT hybrid (Oriental hybrid × Trumpet hybrid) bred at Chungnam-do ARES in 2013. In 2007, interspecific pollination by stigma cut-style of OT hybrid 'Yelloween' and Trumpet hybrid 'Pink Perfection' was conducted to foster the cultivar with flourishing growth, high resistibility to leaf burn and leaf blight. It went through seed culture, multiplication, and seedling from 2007 to 2010. Breeding hybrid evaluation showed that the quality of the hybrid is excellent. From 2011 to 2013, unheated vinyl house cultivation and cultivar registration were performed for characterization. The flower of this lily is clear cream and primrose in color, without spots. It has a width of 18.2 cm and the consistent large flower has a trumpet style, along with many inner and outer perianth overlap. The stem has an oatmeal color and mid-size leaves. Flowering time in the central district starts on the 27th June, which seems to be relatively early. The flower direction is oriented inflorescence and semi-upward, and the cultivar shows robustness to leaf burn and leaf blight. The bulb can be grown with stem and leaf after cutting the flower, as the plant is quite tall. Also, with the high rate of bulb growth, bulb production is convenient. Cut flower production is of high quality with only routine cultivation control (disease, insects, nutrient, and moisture).
