Title: Phalaenopsis plant named ‘SUPHAL1302’

Description:
Latin name of the genus and species:  Phalaenopsis  hybrid. 
     Variety denomination: ‘SUPHAL1302’. 
     BACKGROUND OF THE INVENTION 
     This application relates to a new cultivar of  Phalaenopsis  hybrid. The new variety is the product of a planned breeding program. The new variety originated as a seedling from the crossing of the unpatented, proprietary seed parent  Phalaenopsis  ‘TP17PD’ with the unpatented, proprietary pollen parent referred to as  Phalaenopsis  ‘JWR5S’. The crossing was made by the inventor in his research greenhouse in Chonburi, Thailand in January of 2006. 
     The new variety was first selected by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in December of 2008 in a research greenhouse belonging to the inventor in Chonburi, Thailand. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘SUPHAL1302’, assessing stability of the unique characteristics of this variety. 
     Asexual reproduction of the new cultivar ‘SUPHAL1302’ was first performed at a commercial laboratory belonging to the inventor in Chonburi, Thailand by tissue culture in August of 2009. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, and tissue culture plantlets were in a laboratory belonging to the inventor, and not accessible to the public. Through subsequent propagation, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type. 
     SUMMARY OF THE INVENTION 
     The cultivar ‘SUPHAL1302’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SUPHAL1302’. These characteristics in combination distinguish ‘SUPHAL1302’ as a new and distinct  Phalaenopsis  cultivar:
         1. White flowers with red-purple apical and dorsal lobes.   2. Small leaf size.   3. Small flower size.       

     PARENT COMPARISON 
     Plants of the new cultivar ‘SUPHAL1302’ are similar to the seed parent,  Phalaenopsis  ‘TP17PD’ in most horticultural characteristics. The new variety, however, produces a red-purple lip instead of the yellow one of the seed parent. Additionally the lateral petals are not as pure white as those of the seed parent. 
     Plants of the new cultivar ‘SUPHAL1302’ are similar to the pollen parent,  Phalaenopsis  ‘JWR5S’ in most horticultural characteristics. Plants of the new variety however produce a larger flower than the pollen parent. 
     COMMERCIAL COMPARISON 
     ‘SUPHAL1302’ is similar in most horticultural characteristics to the unpatented variety  Phalaenopsis  ‘SUPHAL1005’. However the new variety, ‘SUPHAL1302’ differs from ‘SUPHAL1005’ in the following characteristics:
         1. Leaves are more upright.   2. Taller plant height.   3. Lateral and apical lobes are red-purple with a yellow base compared to the solid purple of ‘SUPHAL1005’.   4. Different apical lobe shape.       

    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
       The accompanying photograph in  FIG. 1  illustrates in full color a typical plant of ‘SUPHAL1302’ grown in a commercial greenhouse in Zuidbroek, the Netherlands. This plant is approximately 18 months old after deflasking, shown planted in an 11 cm container. 
         FIG. 2  illustrates a close up of the individual flower. 
       The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
