| Abstract: |
A new cultivar of Streptocarpus.times.hybridus plant is characterized by abundant production of unique rhodamine purple flowers on vigorous plants. |
| Claim: |
I claim:
1. A new and distinct variety of Streptocarpus substantially as herein shown and described. |
| Description: |
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct cultivar of Cape Primrose (Streptocarpus.times.hybridus Voss.) known by the name of Rosy-Finch. This selection was developed for the commercial greenhouse industry as a flowering potted plant. Rosy-Finch exhibits compact, vigorous growth, improved heat tolerance, and abundant flower production under progressive commercial practices. The flower color, shape and pattern offers a novel combination not previously available.
In 1978 an ideotype breeding program was initiated to improve the characteristics of Cape Primroses for commercial production. Weismoor Hybrids, J. Innes Hybrids, "Constant Nymph" Series, Oglevees Bavarian Bells, and cultivars of unknown originwere intermated using conventional breeding procedures. F.sub.1 selections were selfed and the best progenies used as background parents for the ideotype. Breeding lines were established in each of the major color classes in the F.sub.3 generation. Selection criteria included floriferousness, good foliage quality and symmetrical compact habit. The pedigree of Rosy-Finch is as follows: ##STR1##
The new cultivar was first asexually reproduced by leaf cuttings in the University of Wisconsin Department of Horticulture greenhouses in Madison, Wis., in 1982. It has been found to retain its distinctive characteristics through successivepropagations.
This new cultivar was evaluated by a jury of industry specialists and professional plant breeders for aesthetic qualities, and screened though production trials for desireable propagation, production and flowering characteristics.
The new cultivar, when grown in a greenhouse in Madison, Wis. has a response time of about 11 weeks. This response time is measured from the potting of plantlets in a five inch pot to the time when the plant has six flowers. Anthesis was about91/2 weeks after potting.
A nonenabling printed publication describes Rosy-Finch (Hopka C and Beck GE (1984) Hortsci. 19:314-316).
DESCRIPTION OF THE DRAWING
The accompanying photograph illustrates the new cultivar, the colors being as nearly true as possible with color illustrations of this type. However, the most accurate representation of the colors is the description (below) referenced to TheRoyal Horticultural Society Colour Chart.
DESCRIPTION OF THE NEW PLANT
The botanical description of the new cultivar follows. The data was collected from asexually propagated plants produced at the University of Wisconsin-Madison, Department of Horticulture. The plant histories were taken on 14-week old plantsproduced in a double-layered polyethylene greenhouse under natural light. Color readings were taken indoors under cool-white fluorescent light. Color references are those displayed in The Royal Horticultural Society Colour Chart.
