초록

At the Flower Research Institute of Chungcheongnam-do agricultural research and extension service, ‘Shusin’ and ‘ST06-005-11’ were crossed and a candidate descendant, ‘ST09-173-06’, was selected based on disease resistance and other morphological traits. We intensively tested the candidate line on various characteristics, including the floral qualities through shading and retarding culture, starting from year 2009. In 2011, we registered this line as the standard chrysanthemum (Dendranthema grandiflorum Ramat.) cultivar ‘Baekseol’. The natural flowering time of 'Baekseol' starts the 24th of October, which is earlier than ‘Jinba’ (29th of October). ‘Baekseol’ is favorable at winter growing season and the flower vase life is 17 days. The cut flower length of ‘Baekseol’ is 87.2 cm, which is shorter than ‘Jinba’ (97.4 cm) and the lateral branch number of ‘Baekseol’ (15.6 per plant) is less than ‘Jinba’ (21.8 per plant). The flower size of ‘Baekseol’ is 14.6 cm (‘Jinba’, 13.4 cm) and the petal number per flower is 430.4 (316.3 per flower for ‘Jinba’). Careful nutrient management is required at t he e arly g rowing s tage. T he s hort d ay t reatment i s appropriate when the plant is approximately 40 - 45 cm. In addition, flower bud differentiation temperature is approximately 16 - 17℃.
