Patent Document

Field of the invention: Botanical classification/cultivar designation:  Doritaenopsis  Orchid cultivar SOGO F2451. 
   BACKGROUND OF THE INVENTION 
   The present invention comprises a new and distinct cultivar of  Doritaenopsis  Orchid, a hybrid of  Doritis×Doritis  of the family Orchidaceae, and hereinafter referred to by the cultivar name, SOGO F2451. The genus  Doritaenopsis  is a member of the family Orchidaceae. 
     Doritaenopsis  comprise a group of bigeneric hybrids generally intermediate in character between the parent genera, which are suitable for cultivation in the home or greenhouse. The parent genera of  Doritaenopsis  are predominantly epiphytic or rock dwelling, and are native to tropical Asia, Malay Archipelago, and Oceania. The species typically have 2-ranked fleshy oblong or elliptic leaves affixed to a short central stem (monopodial growth), which vary in size from 5 to 8 inches to over 2 feet. The leaves may be entirely green or mottled with silver grey. 
     Doritaenopsis  orchid, often referred to ‘Moth Orchids’ in the horticultural trade, are frequently used to furnish cut flowers for the florist trade, or sold as flowering potted plants for home or interiorscape. 
     Doritaenopsis  produce upright racemes, often with many showy flowers, which open in succession beginning with the lowermost. The flowers possess three sepals, and three petals, the lateral ones being alike. The lowermost petal, called the labellum, is three lobed and is often more brightly colored than other flower segments. Flower colors are frequently various shades of pink, white and yellow. 
     Doritaenopsis  orchids are typically propagated from seeds. However,  Doritaenopsis  is capable of being asexually reproduced from offshoots, which frequently arise from the lower bracts of the inflorescence. The resulting plants are detached from the mother plant and may be planted in a suitable substrate. 
   ‘SOGO F2451’ is a product of a planned breeding program conducted by the inventor in Kaohsiung County, Taiwan, R.O.C. The objective of the breeding program is to create new uniform pot-type  Doritaenopsis  Orchid cultivars having attractive flower coloration. The inventor has been addressed himself to the Orchids breeding since 1985. 
   ‘SOGO F2451’ was discovered by the inventor from within the progeny of a cross-pollination of one  Doritaenopsis  orchid, Dtps. ‘SOGO Gotris’ and one  Doritaenopsis  orchid, Dtps. ‘SOGO Golden’ on February 1999, in a controlled environment in Kaohsiung County, Taiwan, R.O.C. 
   Asexual propagation by tissue culture in a laboratory in Pingdong County, Taiwan, R.O.C. has been used to increase the number of plants for evaluation and has demonstrated in a controlled environment in Kaohsiung County, Taiwan, R.O.C. that the unique combination of characteristics as herein disclosed for the new  Doritaenopsis  Orchid are firmly fixed and are retained through successive generations of asexual reproduction. 
   SUMMARY OF THE INVENTION 
   The following traits have been repeatedly observed and are determined to be basic characteristics of ‘SOGO F2451’ which in combination distinguish this  Doritaenopsis  Orchid as a new and distinct cultivar:
         1. Yellow overlaid with purple toward pink base and the red purple with white border colored labellum.   2. Freely flowering habit.   3. Upright, freely branching and sturdy flowering stems.   4. Excellent postproduction longevity.       

   Plants of ‘SOGO F2451’ differ primarily from plants of the parent cultivars in flower color. The main color of petals of Dtps. ‘SOGO Gotris’ is RHS 5A, and the pattern color thereof is RHS 46A. The main color of the petals of Dtps. ‘SOGO Golden’ is RHS 13A. Since this latter parent has a monochromatic flower, there is no pattern color. 
   Currently, there is no commercial cultivar to which ‘SOGO F2451’ can be meaningfully compared.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   ‘SOGO F2451’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, fertilization and day length without any change in the genotype. 
   The observations and measurements describe plants grown in Kaohsiung County, Taiwan, R.O.C. under the conditions, which approximate those generally used in commercial practice. 
   In the following description, color references are made to The Royal Horticultural Society (R.H.S.) Colour Chart. 
   Plants used for the aforementioned photographs and the following detailed botanical description were 18 months in maturity and grown in the pots of 13 cm, in a controlled greenhouse with day-night temperature around 25-18 degree Celsius, and light intensity between 15,000-20,000 lux natural light, in Kaohsiung County, Taiwan, R.O.C.
