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).

Festuca속의 토올페스큐와 메도우페스큐, 그리고 Lolium속의 이탈리안라이그라스들 간에 종속간 잡종을 얻기 위하여 기내수분과 기내배양을 실시하였다. 이들 작물들의 자방과 화분을 채취하여 소독을 하고 주두수분, 주두제거 수분, 배주수분의 3가지 방법으로 기내수분을 실시하였다. 그리고 이들의 배발육상태를 MS, N6 , White's의 배지종류와 IAA Kinetln, BA의 생장조절물질의 처리로서 비교하였다. 1. 토올페스큐, 메도우페스큐, 이탈리안라이그라스의 상호 조합간 기내수분에서 44~92%의 수정율을 나타내었다. 이들의 주두수분은 평균 67.8% 주두제거 수분은 평균 89%의 수정율을 보였으나 배주수분은 평균 61 %로 낮았다. 2. 화본과 수정배주에서 배발육을 촉진하는데는 White's 배지가 가장 효율적이었고 식물생장조절물질의 처리는 IAA(10mg/ )와 Kinetin(0.2 mg/ )의 혼합처리가 무처리보다 효과적이었으나 발아율은 극히 저조하였다 3. 기내배양으로 성숙 배주의 배부조직에서 유관책의 형성과 시원체조직의 분화를 확인할 수 있었으며 배주 내부에 후막세포들의 형성이 관찰되었다.
