Geranium plant named `BFP-825 Salmon Rose`

Abstract

The new and distinct Pelargonium.times.hortorum cultivar named `BFP-825 Salmon Rose` is provided. This new Zonal Geranium was the result of a controlled breeding program wherein a plant designated G4111-4 (non-patented in the United States) was pollinated by the `Laura` cultivar (U.S. Plant Pat. No. 7,087). The new cultivar forms attractive semi-double light rose florets. Medium green foliage with zonation is well retained during shipment. The growth habit is medium self-branching and does not require the use of a growth regulator.

Description

SUMMARY OF THE INVENTION

The present invention comprises a new and distinct Geranium cultivar, botanically known as Pelargonium.times.hortorum Bailey, and hereinafter is referred to by the cultivar name `BFP-825 Salmon Rose`.

The new cultivar is a product of a planned breeding program which had the objective of the creation of a Geranium cultivar that exhibts uniform flowers, medium green foliage, a medium self-branching growth habit that requires no growth regulator, a propensity for rapid rooting, and stable foliage coloration during shipment.

The breeding program that resulted in the production of the new cultivar of the present invention was carried out in a controlled environment during 1992 at Arroyo Grande, Calif., U.S.A. The female parent (i.e., seed parent) was a plant designated G4111-4 (non-patented in the United States) which exhibits semi-double red florets with medium green foliage. The male parent (i.e., pollen parent) was the `Laura` cultivar (U.S. Plant Pat. No. 7,087) which exhibits semi-double lavender florets with medium green foliage. The parentage of the new `BFP-825 Salmon Rose` cultivar can be summarized as follows:

G4111-4.times.`Laura`.

The `BFP-825 Salmon Rose` cultivar was discovered and selected during 1992 as a highly distinctive flowering plant from among the progeny of the stated cross at Arroyo Grande, Calif., U.S.A. This plant was initially designated BFP-825.

It was found that the new cultivar of the present invention:

(a) exhibits attractive semi-double light rose florets,

(b) forms medium green foliage with zonation, and

(c) exhibits a medium self-branching growth habit in the absence of a growth regulator.

When plant material of the `BFP-825 Salmon Rose` cultivar is subjected to standard random amplified polymorphic DNA marker analysis (RAPD) using polymerase chain reaction (PCR) and a known set of DNA primers, it is found to exhibit a distinctive fingerprint map which is on file at the Ball FloraPlant Division of Geo. J. Ball, Inc. at Arroyo Grande, Calif., U.S.A.

The first act of asexual reproduction of the `BFP-825 Salmon Rose` cultivar was accomplished when vegetative cuttings were taken from the initial selection in a controlled environment at Arroyo Grande, Calif., U.S.A., by a technician working under the direction and supervision of the originator of the new cultivar. Horticultural examination of plants resulting from such asexual propagation during 1993 has demonstrated that the combination of unique characteristics as herein described for the `BFP-285 Salmon Rose` cultivar is firmly fixed and is retained through successive generations of such asexual reproduction.

The new `BFP-825 Salmon Rose` cultivar has not been observed under all possible environmental conditions. Accordingly, the described phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length.

Of the many commercial cultivars, the `Americana Cherry Rose` cultivar (U.S. Plant Pat. No. 7,935) is considered to be the most similar to the new cultivar of the present invention. When the new cultivar of the present invention is compared to the `Americana Cherry Rose` cultivar, it is found that the `BFP-825 Salmon Rose` cultivar exhibits distinctly larger umbels (e.g., approximately 11.0 to 13.0 cm. vs. approximately 9.4 to 11.0 cm.) and larger florets (e.g., approximately 4.6 to 5.2 cm. vs. approximately 4.0 to 4.5 cm.).

The new cultivar of the present invention is being marketed by Geo. J. Ball, Inc. under the Designer trademark.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph of FIG. 1 shows a typical plant of the new `BFP-825 Salmon Rose` cultivar with colors being as nearly true as it is reasonably possible to make the same in color illustrations of this character. Typical flower and foliage characteristics are illuustrated. The plant was being grown in a greenhouse at West Chicago, Ill., U.S.A.

DETAILED DESCRIPTION

The following observations, measurements and comparisons describe plants grown in Ball FloraPlant's greenhouses located at West Chicago, Ill., U.S.A., under conditions which approximate those generally used in commercial practice. In the following description, color references are made to the R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color values were determined between 9:00 and 9:30 a.m. on Dec. 27, 1994, under natural light conditions of 2,000 footcandles.
