Abstract

A new and distinct cultivar of Petunia plant named ‘Oscopet2’, characterized by its upright and outwardly spreading plant habit; moderately vigorous growth habit; narrow leaves; star-shaped purple-colored flowers; and relative tolerance to low temperatures.

Description

Botanical designation: Petunia×hybrida.
Cultivar denomination: ‘Oscopet2’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Oscopet2’.
The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new cold-tolerant Petunia cultivars with small leaves and attractive flower coloration.
The new Petunia plant originated from a cross-pollination made by the Inventor in March, 2004 in Asakura-city, Fukuoka, Japan of a proprietary selection of Petunia×hybrida identified as code number peku34, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number peku72, not patented, as the male, or pollen, parent. The new Petunia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Asakura-city, Fukuoka, Japan in May, 2005.
Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled environment in Asakura-city, Fukuoka, Japan since August, 2005, has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Petunia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Oscopet2’. These characteristics in combination distinguish ‘Oscopet2’ as a new and distinct cultivar of Petunia:
    • 1. Upright and outwardly spreading plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Narrow leaves.
    • 4. Star-shaped purple-colored flowers.
    • 5. Relatively tolerant to low temperatures.
Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Petunia have narrower leaves than plants of the female parent selection.
    • 2. Plants of the new Petunia have smaller flowers than plants of the female parent selection.
Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Petunia have narrower leaves than plants of the male parent selection.
    • 2. Flowers of plants of the new Petunia have sharper petal apices than plants of the male parent selection.
Plants of the new Petunia can also be compared to plants of ‘Oostchang’, not patented. In side-by-side comparisons conducted in Asakura-city, Fukuoka, Japan, plants of the new Petunia and ‘Oostchang’ differed primarily in the following characteristics:
    • 1. Plants of the new Petunia were more outwardly spreading than plants of ‘Oostchang’.
    • 2. Leaves of plants of the new Petunia were more viscid than leaves of plants of ‘Oostchang’.
    • 3. Plants of the new Petunia and ‘Oostchang’ differed in flower color as flowers of plants of ‘Oostchang’ had pink-colored flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Petunia, 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 accurately describe the colors of the new Petunia.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Oscopet2’ grown in a container.
The photograph on the second sheet is a close-up view of typical flowers and leaves of ‘Oscopet2’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown in De Kwakel, The Netherlands under commercial practice during the summer in an outdoor nursery. During the production of the plants, day temperatures ranged from 14° C. to 30° C. and night temperatures ranging from 5° C. to 16° C. Plants were pinched one time about two weeks after planting and had been growing for three months when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
