Geranium plant -- BSR-100B Dark Salmon cultivar

Abstract

A new and distinct tetraploid Pelargonium.times.hortorum cultivar named BSR-100B Dark Salmon is provided. This new Zonal Geranium cultivar was the result of a controlled breeding program wherein the Tango cultivar (U.S. Plant Pat. No. 5,933) was pollinated by the Fidelio cultivar (U.S. Plant Pat. No. 5,752). The new cultivar forms attractive semi-double salmon florets which contrast well with dark green foliage which lacks zoning. The attractive dark green foliage coloration is well retained even during shipment. The growth habit is inherently compact and self-branching and does not require the use of growth regulators to maintain such growth characteristic. Good tolerance to wind and rain is exhibited.

Description

SUMMARY OF THE INVENTION

The present invention comprises a new and distinct Geranium cultivar, botanically known as Pelargonium.times.hortorum, and hereinafter is referred to by the cultivar name BSR-100B Dark Salmon.

The new cultivar is the product of a planned breeding program which had as its objective the creation of a highly productive new Geranium cultivar which exhibits attractive blossoms, dark green foliage, a compact self-branching growth habit, no requirement for the use of a growth regulator, a propensity for rapid rooting, and stable foliage coloration during shipment. This objective was satisfactorily fulfilled in the cultivar of the present invention.

The breeding program which resulted in the production of the new cultivar of the present invention was carried out in a controlled environment during 1988 at Santa Maria, Calif., U.S.A. The female parent (i.e., the seed parent) was the TANGO cultivar (U.S. Plant Pat. No. 5,933). Such female parent formed semi-double red florets, and formed dark green foliage. The male parent (i.e., the pollen parent) was the Fidelio variety (U.S. Plant Pat. No. 5,752). Such male parent formed semi-double medium salmon florets, and formed medium green foliage. The parentage of the new cultivar can be summarized as follows:

TANGO.times.FIDELIO.

The seeds resulting from the above pollination were sown and plantlets were obtained which were physically and biologically different from each other. Selective study which was finalized on Jan. 15, 1989, at Santa Maria, Calif. resulted in the identification of a single plant of the new cultivar. This plant initially was designated BSF-100B.

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

(a) exhibits attractive large semi-double salmon florets,

(b) forms attractive dark green foliage which resists breakdown during shipment,

(c) bears leaves which lack zoning, and

(d) exhibits an inherently compact and self-branching growth habit in the absence of growth regulators.

Older peduncles present on plants of the new cultivar after exposure to sunlight commonly assume the coloration of Red-Purple Group 59A.

Asexual reproduction of the new cultivar by vegetative cuttings initially taken on Feb. 10, 1989, and horticulturally examined in a controlled environment on Apr. 15, 1989, at Santa Maria, Calif., has demonstrated that the characteristics of the new cultivar as herein described are firmly fixed and are retained through successive generations of asexual propagation.

When plant material of the BSF-100B Dark Salmon cultivar is subjected to standard random amplified polymorphic DNA marker analysis (RAPD) using polymerase chain reaction (PCR) and a known unique set of DNA primers, it is found to exhibit a distinctive fingerprint map which is on file at the Ball Flora Plant Division of George J. Ball, Inc. at Arroyo Grande, Calif. BSR-100B Dark Salmon has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length.

When the new cultivar of the present invention is compared to the Eclipse Light Salmon cultivar, it is found that THE BSR-100B Dark Salmon cultivar exhibits a darker blossom coloration and a somewhat lighter foliage coloration as specified in greater detail hereafter. The peduncles tend to be Red-Purple Group 60A on the new cultivar and Red-Purple Group 59B on the Eclipse Light Salmon cultivar. Also, the foliage of the Eclipse Light Salmon cultivar exhibits a slight zone which tends to be absent on the BSR-100B Dark Salmon cultivar.

The new cultivar of the present invention is being marketed under the Showcase trademark.
