Oriental × Trumpet Interspecific Hybrid Lily Cultivar with Double Color,‘Crown Bell’

Abstract

A new Oriental × Trumpet (OT) intersectional hybrid lily cultivar (‘Morning Bell’) with flourishing growth and high resistance to leaf burn and Botrytis infection was developed at the Taean Lily Experiment Station of Chungcheongnam-do Agricultural Research and Extension Services in 2015. In 2008, the yellow-flowered female parent, Lilium OT hybrid ‘Altari’ was c rossed with t he p ink-flowered male parent L. Oriental hybrid ‘Solaia’ using a cut-style pollination method. Adaptation trials were conducted on the candidate line to develop various characteristics through in vitro seed culture, multiplication, and seedling from 2009 to 2012. The first selection was made in 2013, and the line was tentatively named ‘OT13-9’. In this study, the external shape type, bulb production, growth, and flowering characteristics of ‘OT13-9’ were compared with those of ‘Candy Club’ from 2013 to 2015. Consumer preference for the evaluated characteristics was surveyed during a lily flower show held at the Flower Research Institute in 2014, and a second selection, named ‘Chungnam OT-3’, was made according to results from the show. This line was registered as the OT intersectional hybrid lily cultivar ‘Morning Bell’ in 2015. The natural flowering time of ‘Morning Bell’ began on July 2, which was similar to that of ‘Candy Club’ at the central district. The plant height of ‘Morning Bell’ was 120.8 cm, and flowers were of the following three types: double color (white-pink), dark with pink spots, or upward blooming. Production of high quality cut flowers and bulbs required careful use of general cultivation techniques, including control of diseases and insects and nutrient/moisture management.
