Geranium plant named "BFP-864 Bright Lavender"

Abstract

The new and distinct Pelargonium.times.hortorum cultivar named `BFP-864 Bright Lavender` is provided. This new Zonal Geranium was the result of a controlled breeding program wherein the a plant designed 3841-3 (non-patented in the United States) was pollinated by the `Fox` cultivar U.S. Plant Pat. No. 7,083). The new cultivar forms attractive semi-double lavender florets commonly with white coloration that radiates outwardly from the bases of the petals. Medium 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-864 Bright Lavender`.

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, 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 3841-3 (non-patented in the United States) which exhibits single dark pink florets with dark green foliage. The male parent (i.e., pollen parent) was the `Fox` cultivar (United States Plant Pat. No. 7,083) which exhibits semi-double purple florets with medium green foliage. The parentage of the new `BFP-864 Bright Lavender` cultivar can be summarized as follows:

3841-3.times.`Fox`.

`BFP-864 Bright Lavender` 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-864.

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

(a) exhibits attractive semi-double lavender florets commonly with white coloration that radiates outwardly from the bases of the petals,

(b) forms attractive medium green foliage, and

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

When plant material of the `BFP-864 Bright Lavender` 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-864 Bright Lavender` 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-864 Bright Lavender` cultivar is fixed and is retained through successive generations of such asexual reproduction.

The new `BFP-864 Bright Lavender` 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 `BFP-721 Bright Lilac` cultivar (United States plant patent application Ser. No. 08/341,991, filed Nov. 14, 1994 ) 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 `BFP-721 Bright Lilac` cultivar, it is found that the `BFP-864 Bright Lavender` cultivar exhibits a less compact growth habit (e.g., approximately 27 to 33 cm. in height vs. approximately 26 to 28 cm.), smaller florets (e.g., approximately 4.2 to 4.4 cm. vs. approximately 4.5 to 5.0 cm. in diameter), and larger leaves (e.g., approximately 9.0 to 10.0.times. approximately 7.6 to 8.5 cm. vs. approximately 8.0 to 9.0 cm..times.approximately 7.0 to 7.5 cm.). The `BFP-864 Bright Lavender` cultivar additionally exhibits longer pedicels, and fewer florets per umbel as specified in greater detail hereafter.

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

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph of FIG. 1 shows the general appearance of an overall plant of the new `BFP-864 Bright Lavender` cultivar with colors being as nearly true as it is reasonably possible to make the same in a color illustration of this character. The plant was being grown in a greenhouse at West Chicago, Ill., U.S.A.

DETAILED DESCRIPTION
