Title: Phalaenopsis orchid plant named ‘PHALDTYK’

Description:
Genus and species:  Phalaenopsis  hybrid. 
     Variety denomination: ‘PHALDTYK’. 
     BACKGROUND OF THE NEW PLANT 
     The present invention relates to a new and distinct cultivar of  Phalaenopsis  plant, botanically known as  Phalaenopsis  hybrid of the Orchidaceae family, commonly referred to as moth orchid, and hereinafter referred to by the variety name ‘PHALDTYK’. 
     The new  Phalaenopsis  plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, The Netherlands. The objective of this breeding program was to create a new  Phalaenopsis  plant with numerous attractive and unique light purple shaded flowers, suitable for potted plant production. 
     The new  Phalaenopsis  plant ‘PHALDTYK’ is a result of cross-pollination made by the inventor in July 2005 in Bleiswijk, The Netherlands of the proprietary female, or seed parent,  Phalaenopsis  hybrid ‘22790-01’ (unpatented) with the proprietary male, or pollen parent,  Phalaenopsis  hybrid ‘7693-020’ (unpatented). 
     The new  Phalaenopsis  was selected by the inventor as a single plant within the progeny of the stated cross-pollination in a controlled greenhouse in Bleiswijk, The Netherlands in October 2008. Asexual reproduction of the new  Phalaenopsis  plant by meristem tissue culture since 2011 in Bleiswijk, The Netherlands, has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations. 
     Plant Breeder&#39;s Rights for this variety have been applied for in Europe on Apr. 18, 2016. ‘PHALDTYK’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing date of this application. 
     SUMMARY OF THE INVENTION 
     The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Bleiswijk, The Netherlands and can be used to distinguish ‘PHALDTYK’ as a new and distinct variety of  Phalaenopsis  plant.
         1) Light purple shaded flowers;   2) 1 to 3 peduncles;   3) Peduncle is long and sturdy; and   4) Shape of the leaf is obovate.       

    
    
     
       DESCRIPTION OF THE PHOTOGRAPHS 
       This new  Phalaenopsis  plant is illustrated by the accompanying photographs which show the overall plant habit including blooms and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken in a greenhouse in Bleiswijk, The Netherlands, from 50-week old plants in June 2016. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

         FIG. 2  shows a close-up of a flower of ‘PHALDTYK’. 
         FIG. 3  shows a close-up of the leaves of ‘PHALDTYK’. 
     
    
    
     DESCRIPTION OF THE NEW VARIETY 
     The following detailed description sets forth the distinctive characteristics of ‘PHALDTYK’. Plants of the new  Phalaenopsis  have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and day length, without, however, any variance in genotype. The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined under 4000-6000 lux natural light in a greenhouse in Bleiswijk, The Netherlands. Observations and measurements were made in June 2016 on 50-week old plants which were planted from a nursery tray in 12 centimeter (diameter) 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.

     COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES 
     The female parent of ‘PHALDTYK’, cultivar ‘22790-01’ (unpatented), is no longer in existence, so a meaningful comparison cannot be made. 
     The male parent of ‘PHALDTYK’, cultivar ‘7693-020’ (unpatented), is no longer in existence, so a meaningful comparison cannot be made. 
     ‘PHALDTYK’ is most similar to the commercial  Phalaenopsis  plants named ‘PHALBARBOK’ (unpatented) and ‘PHALMACHE’ (unpatented). ‘PHALDTYK’ differs from the commercial variety ‘PHALBARBOK’ in that ‘PHALDTYK’ has evenly colored lateral sepals, a light purple column and orange whiskers with yellow tips, whereas ‘PHALBARBOK’ has dotted lateral sepals, a purple column and pale purple whiskers. Additionally, ‘PHALDTYK’ has longer whiskers than ‘PHALBARBOK’. 
     ‘PHALDTYK’ differs from the commercial variety ‘PHALMACHE’ in that ‘PHALDTYK’ has flowers with a shaded pattern, evenly colored lateral sepals, a light purple column, orange whiskers with yellow tips and a rounded petal apex, whereas ‘PHALMACHE’ has flowers with a centered pattern, striped lateral sepals, a purple column, purple whiskers and an emarginated petal apex. Additionally, ‘PHALDTYK’ has longer whiskers and narrower petals than ‘PHALMACHE’.
