Geranium plant named `BFP-837 Scarlet`

Abstract

The new and distinct Pelargonium.times.hortorum cultivar named `BFP-837 Scarlet` is provided. This new Zonal Geranium was the result of a controlled breeding program wherein the a plant designated 11185A (non-Patented in the United States) was pollinated by a plant designated PAS 186-4-4-1 (non-patented in the United States). The new cultivar forms attractive large semi-double scarlet florets commonly with a darker area on two petals of each floret. Dark green foliage is well retained during shipment. A medium self-branching growth habit is exhibited that 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-837 Scarlet`.

The new cultivar is a product of a planned breeding program which had the objective of the creation of a Geranium cultivar that exhibits uniform flowers, dark 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 carred 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 11185A (non-patented in the United States) which exhibits single bright rose florets with medium green foliage. The male parent (i.e., pollen parent) was a plant designated PAS 186-4-4-1 (non-patented in the United States) which exhibits semi-double coral florets with dark green foliage. The parentage of the new `BFP-837 Scarlet` cultivar can be summarized as follows:

11185A.times.PAS 186-4-4-1.

`BFP-837 Scarlet` 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-837.

It was found that the new cultivar of the present invention

(a) exhibits attractive large semi-double scarlet florest commonly having a darker area on two petals of each floret,

(b) forms attractive dark green foliage, and

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

When plant material of the `BFP-837 l Scarlet` 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 `BFP-837 Scarlet` 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-837 Scarlet` cultivar is fixed and is retained through successive generations of such asexual reproduction.

The new `BFP-837 Scarlet` 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 `BSR-232 Light Scarlet` cultivar (U.S. Plant Pat. No. 8,285) 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 `BSR-232 Light Scarlet` cultivar, it is found that the `BFP-837 Scarlet` cultivar exhibits a less compact growth habit (e.g., approximately 29 to 31 cm. in height vs. approximately 23 to 28 cm.), generally larger florets (e.g., approximately 5.6 to 5.9 cm. vs. approximately 4.2 to 4.5 cm.), and generally more petaloids (e.g., approximately 4 to 5 vs. approximately 2 to 4). The `BFP-837 Scarlet` cultivar additionally exhibits longer peduncles, longer pedicels, and larger leaves as specified in greater detail hereafter.

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

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.
