The chrysanthemum cultivar Field Green (Chrysanthemum x morifolium) was developed at the National Institute of Horticultural and Herbal Science, Rural Development Administration (RDA) in 2012. The cultivar Field Green was derived from the artificial crossing in 2008 between two spray chrysanthemum cultivars, Laque Roicks, a maternal p arent with y ellow single t ype flower, and F rill Green, a paternal parent with a green single type and white rust disease resistance. The vigorous plants with green petals and stable flower shapes were selected in 2009. After an evaluation of the characteristics, including shading culture in summer and retarding culture in spring and consecutive selections from 2010 to 2012, the final selection was made. The flowering time of Field Green was October 26 in a natural day length, and year-round production was possible by day-length treatment. This cultivar has single-type flowers with bright green ray florets and green disc florets. The number of ray florets is 18.8, and the flower diameter is 7.1 cm. The growth of the plant is vigorous, with a plant height of 130 cm. Field Green is highly resistant to white rust disease, and vase life is about 20 days in autumn. Number 2013-153 was applied to Field Green on February 20, 2013 for variety protection; its plant variety protection rights were then registered (No. 4839) on April 2, 2014 at the Korea Seed and Variety Service.
