초록

Dendranthema grandiflourm ‘My City’ was developed from a cross cultivar at the Gyeonggi-do Agricultural Research ＆ Extension Services (GARES) in 2010. The cultivar ‘My City’ was initially derived from the cross in 2006 between ‘Fabienna’as a seed parent, a pot chrysanthemum cultivar with pink single type, and ‘Redwing’ as a pollen parent, a pot chrysanthemum cultivar with red single type. The cultivar has single type flowers with red basal color (RHS Orange Red Group N34A) mix yellow petals (RHS Yellow Group 11A). Trials for evaluation was conducted from 2008 to 2010 for a selection of that cultivar,including a shading culture in spring and a retarding culture in winter. The natural flowering time of ‘My City’ was October 26th, and year-round flowering is possible by shading or retarding treatment. The diameter of flower is 56.4mm. Numbers of flowers per stem and petals per flower of ‘My City’ were 13.4 and 26.2, respectively. Its leaf color is green (RHS Green Group 138B) and plant height is about 20.1 cm. The line was named as Gyeongkyo ‘B1-13’ and phenotype was evaluated 2010 as a new cultivar. This cultivar is weak to white rust and consumer’s preference of new pot chrysanthemum is high level than control. We expect that ‘My City’ has a great potential for year round cultivation and domestic market due to this cultivar has attractive flower color, reasonable plant height and vigorous branch growth.
