Dahlia plant named `Gallery Salvador`

Abstract

A distinct cultivar of Dahlia plant named `Gallery Salvador`, characterized by its suitability for potted plants, garden or patio plants, or as cut flowers; upright and spreading, compact and freely branching plant habit; medium green foliage; early and profuse flowering; rapid growth rate; large decorative-type inflorescences that are about 12 cm in diameter; light pink-colored ray florets; and good postproduction longevity.

Description

The present invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia hybrid and referred to by the cultivar name `Gallery Salvador`.

The new cultivar is a product of a planned breeding program conducted by the inventor in Lisse, The Netherlands. The objective of the breeding program is to create compact Dahlia cultivars that flower early and profusely with desirable ray floret color and good post-production longevity.

The new cultivar originated from a cross made by the inventor in the summer of 1992, of the nonpatented commercial cultivar `Oriental Dream` as the female, or seed, parent with the nonpatented commercial cultivar `Tout a Toi` as the male, or pollen, parent. Compared to plants of the parent cultivars, the new Dahlia is more compact, more freely branching and inflorescences have a different ray floret color.

The cultivar `Gallery Salvador` was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Lisse, The Netherlands, in 1992. The selection of this plant was based on its compact and freely branching habit, unique ray floret color, floriferousness and good postproduction longevity.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Lisse, The Netherlands, has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.

The cultivar `Gallery Salvador` has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Gallery Salvador`. These characteristics in combination distinguish `Gallery Salvador` as a new and distinct cultivar:

1. Suitable for potted plants, garden or patio plants, or as cut flowers.

2. Upright and spreading, compact and freely branching plant habit.

3. Medium green foliage.

4. Early and profuse flowering.

5. Rapid growth rate.

6. Large decorative-type inflorescences that are about 12 cm in diameter.

7. Light pink-colored ray florets.

8. Good postproduction longevity with open inflorescences maintaining good substance and color for about 14 days and plants maintaining good substance and flowering for 3 to 4 months.

The accompanying photograph illustrates the overall appearance of the new cultivar. The colored photograph comprises a side perspective view of a typical flowering plant of `Gallery Salvador`. This photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Floret and foliage colors in the photograph may differ from the actual colors due to light reflectance.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Lisse, The Netherlands, under conditions which approximate those generally used in commercial potted Dahlia production with day temperatures averaging 21.degree. C. and night temperatures averaging 14.degree. C. Plants were grown during the summer and measurements and numerical values were averages derived from typical flowering plants in September.
