Breeding of the mini-type phalaenopsis cultivar ‘yellow green’, having deep-yellow flowers with a red lip

A new Phalaenopsis cultivar, ‘Yellow Green’, was bred at Kangsan Orchid, Korea. The new cultivar has small, deep-yellow flowers with a red lip, and was introduced by artificial crossing of the Phalaenopsis cultivar ‘Sogo Pride F-1016' and the Phalaenopsis cultivar ‘Tzu Ching Glint’. The elite individual KS-752-1, later named as ‘Yellow Green’, was selected among 300 individual progenies through over three years (2008-2010) of intensive selection for excellent vegetative and flowering characteristics. In the 1st (2011-2013) and 2nd (2014-2015) years of breeding, characteristic analysis was performed through stability and uniformity tests. ‘Yellow Green’ has flowers that are deep-yellow (RHS#: 5A) with a red lip (RHS#: N74A) and are small in size, measuring 4.6 cm in length and 4.9 cm in width. The flowers are light-green at the beginning and gradually turn to deep-yellow. Also, the flower buds are produced easily. ‘Yellow Green’ flowers are a compound raceme type, suitable for pot cultivation. Its leaves grow horizontally and are about 17.5 cm in length and 6.2 cm in width. This cultivar is characterized by the absence of genetic variation, fast in vitro propagation, and vigorous growth that facilitates cultivation. This cultivar was registered (Reg.#:6268) with the Korea Seed & Variety Service (KSVS) on July 18, 2016, and the plant breeder’s right is currently owned by the Kangsan Orchid Company, Korea.
