Abstract

A distinct cultivar of Petunia plant named ‘Cobink’, characterized by its mounded and outwardly spreading plant habit; freely and continuous branching habit; and numerous pink double flowers.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia axillaris, and hereinafter referred to by the cultivar name Cobink.
The new Petunia is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The new Petunia originated from a cross made by the Inventor in 1997 of a proprietary selection of Petunia axillaris identified as X96.410.1 as the female, or seed, parent with the Petunia axillaris cultivar Silk Road, U.S. Plant patent application Ser. No. 09/450,095, as the male, or pollen, parent. The new Petunia was selected on the basis of its flower form, flower color and spreading growth habit.
Asexual reproduction of the new cultivar by terminal cuttings taken at Cobbitty, New South Wales, Australia, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Cobink have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.
The following traits have been repeatly observed and are determined to be the unique characteristics of ‘Cobink’. These characteristics in combination distinguish ‘Cobink’ as a new and distinct cultivar:
1. Mounded and outwardly spreading plant habit.
2. Freely and continuous branching habit.
3. Numerous double pink flowers.
Compared to plants of the single-flowered female parent, the selection X96.410.1, plants of the new cultivar have darker pink-colored flowers.
Plants of the male parent, the cultivar Silk Road, differ from plants of the new cultivar primarily in flower color as plants of ‘Silk Road’ have white-colored flowers.
Plants of the cultivar Cobink are similar in flower color to plants of the single-flowered cultivar Cascadia Charme, not patented. However in side-by-side comparisons conducted in Encinitas, Calif., plants of the cultivar Cobink differ from plants of the cultivar Cascadia Charme in the following characteristics:
1. Plants of the new Petunia are more compact than of plants of the cultivar Cascadia Charme.
2. Plants of the new Petunia have slightly smaller leaves and shorter internodes than plants of Cascadia Charme.
3. Plants of the new Petunia flower somewhat later than plants of the cultivar Cascadia Charme.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors.
The photograph at the top of the sheet comprises a side perspective view of three typical plants of ‘Cobink’ grown in a 25-cm container.
The photograph at the bottom of the sheet comprises close-up views of typical flower buds, open flowers and leaves of ‘Cobink’ (left side of photograph) and ‘Cascadia Charme’ (right side of photograph).
DETAILED BOTANICAL DESCRIPTION
The following observations, measurements and values describe plants of the new cultivar grown three plants per 25-cm containers in Encinitas, Calif. For the first six weeks after planting, plants were grown in plastic-covered greenhouses with average day and night temperatures of 23.3 and 18.9° C., respectively, and light levels averaging 3,000 foot-candles. Plants were then grown in full sun for about 12 weeks with day and night temperatures averaging 18 and 13° C., respectively, and light levels averaging 8,000 foot-candles.
Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
