| Abstract: |
This invention relates to a new and distinct cultivar of geranium (Pelargonium.times.Xhortorum) named `Centennial` substantially as described herein, characterized as being particularly well adapted to both commercial greenhouse production and garden performance, and as being early flowering, floriferous, self-branching, compact and producing bright scarlet semidouble flowers. |
| Claim: |
What is claimed is:
1. A new and distinct cultivar of geranium substantially as shown and described herein, characterized as being particularly well adapted to both commercial greenhouseproduction and garden performance and as being early flowering, floriferous, self-branching, compact, and producing bright scarlet, semidouble flowers. |
| Description: |
The present invention relates to a newand distinct cultivar of geranium (Pelargonium.times.Xhortorum) called `Centennial`. This cultivar is early flowering, floriferous, self-branching, compact, and produces bright scarlet, semidouble flowers. Moreover, the cultivar is particularly welladapted to both commercial greenhouse production and garden performance.
The cultivar was developed from an organized, scientifically designed breeding program carried out at the Department of Horticulture, The Pennsylvania State University, University Park, Pa. 16802. The breeding program was designed to create newgeranium genotypes with clear, bright colors which combined the flowering ability and compactness of European cultivars with the heat tolerance, low-light tolerance, and excellent greenhouse production qualities of Penn State material. The pedigree ofthis cultivar is as follows: ##STR1##
Centennial may share some common traits with the patented cultivar `#(812)-(82-116-13)` because they are selections from the same parentage and because they both conform to the general selection criteria designed into the breeding program. `Centennial` is distinguished from `#821-(82-116-13)` by having: longer internodes and leaf petioles which result in a larger yet compact plant; a substantially greater number of florets per inflorescence which improves floral conformation; a greaterfloret which adds to the attractiveness of individual florets, number of petals per and by shorter peduncles which place the inflorescences closer to the foliage and provide a much more balanced floral display. In addition, floral pigmentation is moreuniform; `Centennial` does not exhibit the dark red spot which is characteristic of `#821-(82-116-13)`.
The selection was asexually propagated by cuttings and the reproductions ran true.
BRIEF DESCRIPTION OF THE DRAWING
The FIGURE illustrates in color the cultivar including foliage and flowers.
With reference to the detailed description of the cultivar which follows, the test plant was grown in a glasshouse under full, natural light, at a nighttemperature of approximately 58.degree. F., and a day temperature of approximately 68.degree. F. Soilless medium was fertilized with every watering with 200 ppm nitrogen from 15-16-17.
Color readings were taken under incandescent light at 200 foot candles and color identification was by reference to the Royal Horticultural Society Colour Charts, except where common terms of color definition are employed.
