Description:
BOTANICAL CLASSIFICATION 
       [0001]      Phalaenopsis  sp. 
       VARIETY DENOMINATION 
       [0002]    ‘Queen V6’. 
         [0003]    The present invention relates to botanical classification/cultivar designation:  Phalaenopsis  Orchid cultivar Queen V6. 
       BACKGROUND OF THE INVENTION 
       [0004]    The present invention comprises a new and distinct cultivar of  Phalaenopsis  Orchid, and hereinafter referred to by the cultivar name, ‘Queen V6’. 
         [0005]    The new cultivar is a planned breeding program conducted by the inventor in Tainan, Taiwan. The objective of the breeding program is to create new uniform pot-type  Phalaenopsis  Orchid cultivars having attractive flower coloration. 
         [0006]    The new cultivar was discovered by the inventor from within the progeny of a cross-pollination of two unidentified proprietary selections of  Phalaenopsis  Orchids, not patented, on Dec. 16, 1999, in a controlled environment in Tainan, Taiwan. 
         [0007]    Asexual propagation by tissue culture in a laboratory in Tainan, Taiwan has been used to increase the number of plants for evaluation and has demonstrated that the unique combination of characteristics as herein disclosed for the new  Phalaenopsis  Orchid, ‘Queen V6,’ are retained through successive generations of asexual reproduction. 
       SUMMARY OF THE INVENTION 
       [0008]    The following traits have been repeatedly observed and are determined to be basic characteristics of new cultivar which in combination distinguish this  Phalaenopsis  Orchid, ‘Queen V6,’ as a new and distinct cultivar: 
         [0009]    1. Flowers whose width in front view is broad, about 13 to 14 cm. 
         [0010]    2. Flowers having a persistent habit. 
         [0011]    3. Upright and sturdy flowering stems. 
         [0012]    4. Excellent postproduction longevity. 
         [0013]    Plants of the new cultivar differ primarily from plants of the parent cultivar in flower shape. 
         [0014]    Plants of the new  Phalaenopsis  Orchid can be compared to plants of the cultivar P. SogoYukidian, disclosed in R.H.S. In side-by-side comparisons conducted in Tainan, Taiwan, plants of the new  Phalaenopsis  Orchid differed from plants of the cultivar P. Sogo Yukidian in the following characteristics: 
         [0015]    1. Plants of the new  Phalaenopsis  Orchid are bigger than plants of the cultivar P. Sogo Yukidian. 
         [0016]    2. Plants of the new  Phalaenopsis  Orchid have broader leaves than plants of the cultivar P. Sogo Yukidian. 
         [0017]    3. Plants of the new  Phalaenopsis  Orchid have shorter inflorescences than plants of the cultivar P. Sogo Yukidian. 
         [0018]    4. Plants of the new  Phalaenopsis  Orchid have thinner peduncles than plants of the cultivar P. Sogo Yukidian. 
         [0019]    5. Plants of the new  Phalaenopsis  Orchid have larger flowers than plants of the cultivar P. Sogo Yukidian.

       [0024]    Plants of the new cultivar have not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light intensity, without however, any change in genotype. In the following description, color references are made to The Royal Horticultural Society Colour Chart, except where general terms of ordinary dictionary significance are used. 
         [0025]    Plants used for the aforementioned photographs and following detailed botanical description were grown in 12-cm containers in Tainan, Taiwan, in a greenhouse. The average temperature during vegetative growth was about 25-33° C., and the average temperature during reproductive growth was about 17-25° C.
