| Abstract: |
An African violet named Rhode Island having intensive pink flower color, with a somewhat deeper pink tone in the center, and frilled edges. The variety is profuse in bloom, with up to 15 flower stems each carrying up to 12 or more flowers per stem. The growth is uniform, the leaves dark green and shiny, and the flowers long lasting and non-dropping. The plant is saleable within 8 weeks after potting. |
| Claim: |
I claim:
1. A new and distinct cultivar of African violet plant known by the cultivary name Rhode Island and particularly characterized by the combined features of intensive pink flower color,with a somewhat darker pink center; profuse blooming habit providing a corolla which appears rather fluffy during full bloom; dark green shiny leaves; excellent growth habit, producing up to 15 flower stems, each of which contains up to 12 or moreflowers per stem, with the flowers being long lasting and non-dropping, and by its ability to provide a saleable plant within 8 weeks after potting. |
| Description: |
The present invention comprises a new anddistinct cultivar of African violet plant, botanically known as Saintpaulia ionantha, and hereinafter referred to by the cultivar name Rhode Island.
The new cultivar was referred to during the breeding and selection process by the designation d 29/23, and is a product of a planned breeding program. The basic objective of the breeding program was to create a new African violet cultivar havingintensive pink flower color with frilled petal edges.
The new cultivar was originated from a cross made in a controlled breeding program in Isselburg, West Germany. The female, or seed parent was a cultivar designated b 244/10 pink. The male, or pollen parent was a cultivar designated b 16/6 pinkfrilled.
The new cultivar Rhode Island was discovered and selected by me as a flowering plant within the progeny of the stated cross in a controlled environment in Isselburg, West Germany. Asexual reproduction of the new cultivar by leaf cuttings and bydivision of shoots, as performed by me at Isselburg, West Germany, has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and are retained through successive generations of asexual reproduction.
Rhode Island 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. The following observations, measurementsand values describe the new cultivar as grown in Isselburg, West Germany, under greenhouse conditions which closely approximate those generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Rhode Island, which in combination distinguish this African violet as a new and distinct cultivar:
1. Intensive pink flower with deeper tone in center, and filled edges.
2. Mature flowers darker in color, returning to pink when old.
3. Profuse and fluffy in bloom; older flower stems bend to tilt sidewards to make space for upcoming younger flowers from center.
4. Up to 15 flower stems, carrying between 5-12 or more flowers per stem.
5. Uniform in growth.
6. Saleable within 8 weeks after potting.
7. Dark green shiny leaves.
8. Long lasting and non-dropping flowers.
The accompanying photographic drawing shows a typical specimen plant of the new cultivar. The colors appearing in the photograph are as true as possible with color illustrations of this type.
In the following description, color references are made to the Horticultural Colour Chart (HCC) issued by Wilson Colour Ltd., except where general colors of ordinary significance are referred to. Color values were taken under natural lightconditions approximately mid-day in Isselburg, West Germany. It is noted that the color reproduction tends toward pink rather than pinkish purple, although the true color appears in the veining of the flowers. The color values stated below are correct.
