Phalaenopsis Hybrid
‘PHALDISAM’
The present invention comprises a new and distinct cultivar of Phalaenopsis plant, botanically known as Phalaenopsis of the Orchidaceae family, and hereinafter referred to by the cultivar name ‘PHALDISAM’.
Phalaenopsis comprises a genus of about 60 species of herbaceous perennials many of which, or the hybrids thereof, are suitable for cultivar in the home or greenhouse. Phalaenopsis is predominantly epiphytic or rock dwelling, and is native to tropical Asia, the Malay Archipelago, and Oceania. The species typically has 2-ranked, fleshy, oblong or elliptic leaves affixed to a short central stem (monopodial growth), which vary in size from 12 to 20 cm to over 60 cm. The leaves may be entirely green or mottled with silver grey.
Phalaenopsis orchids, often referred to as ‘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.
Phalaenopsis produces upright or pendent lateral racemes or panicles, 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 petals, called the labellum, are three-lobed and are often more brightly-colored than the other flower segments. Flower colors include various shades of pink, white, yellow, and red-brown.
Phalaenopsis orchids are typically propagated from seeds. Asexual propagation of Phalaenopsis is often done from off-shoots which arise from the lower bracts of the inflorescence. The resulting plants are detached from the mother plants and may be planted in a suitable substrate.
The new Phalaenopsis ‘PHALDISAM’ is particularly characterized by its attractive and unique white flowers with dark purple flecks, economical propagation by tissue culture, rapid growth, and a plant dimension suitable for packaging and shipping to the market.
‘PHALDISAM’ is a product of a planned breeding program conducted in Bleiswijk, The Netherlands.
The new Phalaenopsis ‘PHALDISAM’ originated from a cross made in August 2005 in Bleiswijk, The Netherlands. The female parent is a white flecked Phalaenopsis pot plant named ‘21062-0018’ (unpatented), while the male parent is a pink Phalaenopsis pot plant named ‘04347-0001’ (unpatented). A single plant was selected in August 2008 and has been asexually reproduced repeatedly by meristem tissue culture in Bleiswijk, The Netherlands over a 3.5-year period. The new variety has been found to retain its distinctive characteristics through successive asexual propagations.
Asexual reproduction of ‘PHALDISAM’ by tissue culture was first performed in July 2011 in Bleiswijk, The Netherlands and has demonstrated that the new cultivar is firmly fixed and retained through successive generations of asexual reproduction.
Plant Breeder's Rights for this variety have been applied for in Europe on Apr. 25, 2014. ‘PHALDISAM’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing date of this application.
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Bleiswijk, The Netherlands.
1) White flowers with dark purple flecks, the intensity of which depends on the temperature during opening of the flower buds;
2) 1 to 2 peduncles;
3) Peduncle is long and moderate;
4) The shape of the leaf is obovate and moderately elongated; and
5) Plants are propagated by meristem tissue culture.
This new Phalaenopsis plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 50-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in October 2014.
The following detailed description sets forth the distinctive characteristics of ‘PHALDISAM’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 50-week old plants which were planted from tissue culture in 12 centimeter pots and grown in a greenhouse between 27° C. to 29° C. for 30 weeks, continued by a cooling period of 8 weeks between 18° C. to 20° C. and 12 weeks in a greenhouse of 21° C. Observations were made in October 2014. Color readings were taken under 4-6000 lux natural light in the greenhouse. Color references are primarily to The RHS Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).
‘PHALDISAM’ differs from female parent ‘21062-0018’ (unpatented) in that ‘PHALDISAM’ has a red-purple lip with a small yellow spot towards the callus, whereas ‘21062-0018’ has a yellow-white and lilac lip. Additionally, ‘PHALDISAM’ has a type V lateral lobe and darker green leaves, whereas ‘21062-0018’ has a type IV lateral lobe and lighter green leaves.
‘PHALDISAM’ differs from male parent ‘04347-0001’ (unpatented) in that ‘PHALDISAM’ has flowers that are white with dark purple flecks and a dark purple callus, whereas ‘04347-0001’ has flowers that are evenly pink and a yellow dotted callus. Additionally, ‘PHALDISAM’ has more narrow petals with undulation of the margin, whereas ‘04347-0001’ has broader petals with an entire margin.
‘PHALDISAM’ differs from commercial variety ‘PHALFUNEL’ (unpatented) in that ‘PHALDISAM’ has a red-purple apical lobe of the lip with a small yellow spot towards the callus and shorter whiskers, whereas ‘PHALFUNEL’ has a yellow-white apical lobe of the lip and longer whiskers. Additionally, ‘PHALDISAM’ has a purple column, whereas ‘PHALFUNEL’ has a white column.
