Patent Abstract:
A new and distinct cultivar of  Doritaenopsis  plant named ‘Moon N12’ has white petals and sepals with light purple shadow near the labellum, upright and sturdy flowering stems, and excellent postproduction longevity.

Full Description:
Botanical classification:  Doritaenopsis  sp. 
   Variety denomination: ‘Moon N12’. 
   The present invention relates to botanical classification/ cultivar designation:  Doritaenopsis  Orchid cultivar Moon N12. 
   BACKGROUND OF THE INVENTION 
   The present invention comprises a new and distinct cultivar of  Doritaenopsis  Orchid, and hereinafter is referred to by the cultivar name, ‘Moon N12’. 
   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  Doritaenopsis  Orchid cultivars having attractive flower coloration. 
   The new cultivar was discovered by the inventor from within the progeny of a cross-pollination of two unnamed proprietary selections of  Doritaenopsis  and  Phalaenopsis  Orchids, not patented, on Oct. 18, 1999, in a controlled environment in Tainan, Taiwan. 
   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  Doritaenopsis  Orchid, ‘Moon N12,’ 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 a new cultivar which, in combination, distinguish this  Doritaenopsis  Orchid as a new and distinct cultivar:
         1. Flowers whose width in front view is broad, about 11 to 13 cm.   2. Flowers having a persistent habit.   3. Upright, freely branching and sturdy flowering stems.   4. Excellent postproduction longevity.       

   Plants of the new cultivar differ primarily from plants of the parent cultivar in flower color. 
   Plants of the new  Doritaenopsis  Orchid can be compared to plants of the male parent  Phalaenopsis  and the female parent  Doritaenopsis . In side-by-side comparisons conducted in Tainan, Taiwan, plants of the new  Doritaenopsis  Orchid differed from plants of the male parent  Phalaenopsis  and the female parent  Doritaenopsis  in the following characteristics:
         1. Plants of the new  Doritaenopsis  Orchid are bigger than plants of the male parent  Phalaenopsis  and the female parent  Doritaenopsis.      2. Plants of the new  Doritaenopsis  Orchid have broader leaves than plants of the male parent  Phalaenopsis  and the female parent  Doritaenopsis.      3. Plants of the new  Doritaenopsis  Orchid have shorter inflorescences than plants of the male parent  Phalaenopsis  and the female parent  Doritaenopsis.      Plants of the new  Doritaenopsis  Orchid have stronger peduncles than plants of the male parent  Phalaenopsis  and the female parent  Doritaenopsis.
