Abstract

A distinct cultivar of Petunia plant named ‘MPD2’, characterized by its compact, outwardly spreading and cascading plant habit; freely branching habit; and numerous small double flowers that are light purple in color with dark violet-colored venation.

Description

Botanical designation: Petunia×hybrida.
Cultivar denomination: ‘MPD2’.
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 cultivar name MPD2.
The new Petunia is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the breeding program is to create new Petunias with numerous small double flowers with attractive flower colors.
The new Petunia originated from a cross-pollination made by the Inventor in December, 2001 of a proprietary Petunia×hybrida selection identified as X01.154.3, not patented, as the female, or seed parent, with a proprietary Petunia×hybrida selection identified as PKC27, not patented, as the male, or pollen parent. The new Petunia was selected as a single plant from the resulting progeny of the cross-pollination by the Inventor in a controlled environment in Cobbitty, New South Wales, Australia in October, 2002.
Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Cobbitty, New South Wales, Australia since October, 2002 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 MPD2 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique charcteristics of ‘MPD2’. These chacteristics in combination distinguish ‘MPD2’ as a new and distinct Petunia cultivar:
    • 1. Compact, outwardly spreading and cascading plant habit.
    • 2. Freely branching habit.
    • 3. Numerous small double flowers that are light purple in color with dark violet-colored venation.
Plants of the Petunia differ primarily from plants of the female parent selection in flower form as plants of the female parent selection have single flowers. Compared to plants of the male parent selection, plants of the new Petunia are more compact and have a more spreading plant habit. In addition, plants of the new Petunia differ primarily from plants of the male parent selection in flower coloration as plants of the male parent selection have white-colored flowers.
Plants of the new Petunia can be compared to plants of the cultivar Tedropur, disclosed in U.S. Plant Pat. No. 14,179. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Petunia differed from plants of the cultivar Tedropur in the following characteristics:
    • 1. Plants of the new Petunia were more spreading than plants of the cultivar Tedropur.
    • 2. Plants of the new Petunia and the cultivar Tedropur differed in flower coloration as plants of the cultivar Tedropur have purple violet-colored flowers.
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 accurately describe the colors of the new Petunia.
The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘MPD2’ grown in a container.
The photograph at the top of the sheet comprises a close-up view of typical flowers and leaves of ‘MPD2’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Lompoc, Calif., under commercial practice during the winter and early spring in a polycarbonate-covered greenhouse with day temperatures ranging from 21 to 24° C., night temperatures ranging from 16 to 18° C., and light levels ranging from 5,000 to 9,000 foot candles. Plants were grown for about 14 weeks with one plant per 14-cm container. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
