Abstract:
A new and distinct cultivar of New Guinea  Impatiens  plant named ‘Balcebpiel’ characterized by its large pink-colored flowers, medium green-colored foliage, medium upright, mounded growth habit, and excellent basal branching.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     The present invention relates to a new and distinct New Guinea  Impatiens  plant botanically known as  Impatiens Hawkeri  and hereinafter referred to by the cultivar name ‘Balcebpiel’.  
         [0002]     The new cultivar was developed by the inventor in a controlled breeding program during June 2000 at Arroyo Grande, Calif. The objective of the breeding program was to develop New Guinea  Impatiens  cultivars with numerous large flowers, excellent basal branching and upright compact to moderate growth habits.  
         [0003]     The female (seed) parent of ‘Balcebpiel’ was the proprietary  Impatiens Hawkeri  selection designated ‘1585-4’ (not patented), characterized by its upright growth habit, light pink-colored flowers and medium green-colored foliage. The male (pollen) parent of ‘Balcebpiel’ was proprietary  Impatiens Hawkeri  selection designated ‘BFP-2565’ (not patented), characterized by its pink-colored flowers and dark green-colored foliage. ‘Balcebpiel’ was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination in January of 2001 at Arroyo Grande, Calif. and was initially designated ‘3183-2’.  
         [0004]     Asexual reproduction of the new cultivar by terminal stem cuttings taken since January 2001 at West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.  
       SUMMARY OF THE INVENTION  
       [0005]     It was repeatedly found that the cultivar of the present invention:  
         [0006]     1. Exhibits large round pink-colored flowers,  
         [0007]     2. Forms medium green-colored foliage,  
         [0008]     3. Exhibits a good basal branching character, and  
         [0009]     4. Exhibits a medium, upright mounded growth habit.  
         [0010]     Plants of the new cultivar differ from plants of the female parent primarily in flower color and from plants of the male parent primarily in foliage color.  
         [0011]     Of the many commercially available New Guinea  Impatiens  cultivars known to the inventor, ‘Balcebpiel’ is most similar to ‘BFP-844’ (U.S. Plant Pat. No. 11,415). However, in side-by-side comparisons conducted in West Chicago, Ill., plants of the new cultivar differed from plants of ‘BFP844’ in the following characteristics.  
         [0012]     1. Plants of the new cultivar have more branches than plants of ‘BFP844’,  
         [0013]     2. Plants of the new cultivar have shorter branches than plants of ‘BFP844’, and  
         [0014]     3. Plants of the new cultivar have larger flowers than plants of ‘BFP844’. 
     
    
     BRIEF DESCRIPTION OF THE PHOTOGRAPH  
       [0015]     The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balcebpiel’. The plants were grown from rooted cuttings for 14 weeks in a greenhouse at West Chicago, Ill.  
         [0016]      FIG. 1  illustrates a side view of the overall growth and flowering habit of ‘Balcebpiel’.  
         [0017]      FIG. 2  illustrates a close-up view of a single flower of ‘Balcebpiel’. 
     
    
     DETAILED DESCRIPTION  
       [0018]     The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length without, however, any variance in genotype.  
         [0019]     The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 1995 edition, except where general color terms of ordinary significance are used. The color values were determined on Sep. 11, 2003 between 1:00 and 1:45 p.m. under natural daylight conditions.  
         [0020]     The following measurements and comparisons describe plants produced from cuttings taken from stock plants and grown under greenhouse conditions comparable to those used in commercial practice. The plants were grown in 10 cm pots for 14 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 72° F. during the day and approximately 65° F. during the night. Greenhouse light levels were maintained at approximately 4,000-7,000 footcandles during the day.
