Breeding for New Evergreen Dianthus Cultivar 'URI 2010-6' with Bright Red Flower Color

摘要

A new Dianthus cultivar 'URI 2010-6' was selected among F-1 progenies from a cross between interspecific hybrid 'Evergreen Emerald' as the seed parent and D. chinensis 'Ruby' as the pollen parent. In 2007, the cross was made, and the seedlings of FT progenies were obtained and investigated. After three rounds of characteristic evaluation from 2008 to 2010, a clone was selected and registered as 'URI 2010-6' at the Korea Seed and Variety Service (plant variety protection number: 4431) in 2011. The (lower of 'URI 2010-6' is caryophyllaceous, single type, and mainly bright red (Red, N79C) with secondary white (White, N155C) on the edge or as spots on the petal. The flower has diameter of 2.7 cm and length of 0.8 cm. This cultivar blooms continuously about 150 d on average and may be used as evergreen plant during winter months.
