Abstract:
A new and distinct Asiatic Lily Hybrid named `PAC Sun` characterized by having large yellow flowers in a quality inflorescence on genetically dwarf stems with dense foliage excellent for pot plant production.

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of Lily hybrid, referred to commercially as an upright Asiatic hybrid pot lily, and given the cultivar name `PAC Sun`. 
     This invention was developed by controlled breeding in Aurora, Oreg. using (OH-6 ×OB-4), a proprietary, non-released plant as the seed parent and 9-80, another proprietary, non-released plant as the pollen parent. 
     This invention has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length, without, however, any variation in genotype. 
     The following traits have been repeatedly observed and are determined to be the basic characteristics of this invention which in combination distinguish this lily as a new and distinct cultivar: 1) large flowers of a bright yellow color with very few spots in a beautiful inflorescence; 2) beautiful, large, yellow green colored buds; 3) genetically dwarf stems excellent for pot plant production; 4) very uniform growth habit; 5) good vigor; and 6) good, dense foliage. Bulbs of this plant may be precooled and forced out of season for uniform pot plant production. In addition, this new lily shows good disease resistance. 
     This invention is best compared to `Lemon Pixie` (U.S. Plant No. 6,367). Compared to `Lemon Pixie`, this invention has better flower color, better foliage. Field bulb production of this new plant yields fewer multi-nosed erect concentric bulbs than `Lemon Pixie`. Multi-nosed bulbs are not salable for commercial forcing. The new plant is also shorter than `Lemon Pixie` land earlier blooming by one week. 
     Asexual reproduction of this new variety has been accomplished at Cebeco Lilies, Inc., Aurora, Oreg., by scaling and tissue culture. The resulting plants have shown that the above-mentioned unique features are stable and reproduce true to type in each successive propagation. 
    
    
     DESCRIPTION OF THE DRAWING 
     FIG. 1 is a close-up photograph which illustrates in greater detail a single flower of the new plant. 
     FIG. 2 is a photograph showing the `PAC Sun` lily. 
    
    
     The photographs of the drawing were taken in June 1996 in a studio and illustrate the typical flower and foliage form, with color as true as reasonably possible in this type of color photograph. This stem was grown in the Cebeco greenhouse in Aurora, Oreg. 
     DETAILED DESCRIPTION 
     The following is a detailed description of the invention based on plants produced under commercial practices in the Cebeco Lilies, Inc. fields in Hubbard, Oreg. in July 1996. Color references are made to The Royal Horticultural Society Colour Chart, except where the context indicates a term having its ordinary dictionary meaning.
