Petunia plant named ‘X00-155-1’

Abstract

A new and distinct cultivar of Petunia plant named ‘X00-155-1’, characterized by its compact, mounded and outwardly spreading plant habit; freely and continuous branching habit; small leaf size; numerous small light violet-colored flowers with purple-colored throats; and resistance to Botrytis and Powdery Mildew.

Description

Botanical classification: Petunia×hybrida cultivar X00-155-1.

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 X00-155-1.

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 outwardly spreading Petunias with numerous small flowers with attractive flower colors.

The new Petunia originated from a cross-pollination made by the Inventor in 1999 of a proprietary Petunia selection identified as X99.23.9, not patented, as the female, or seed parent, with a proprietary Petunia selection identified as X99.3.7, 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 1999, in Cobbitty, New South Wales, Australia, on the basis of its outwardly spreading habit and numerous small flowers.

Asexual reproduction of the new cultivar by vegetative cuttings taken in Cobbitty, New South Wales, Australia since 2000 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 X00-155-1 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 characteristics of ‘X 00- 155-1’. These characteristics in combination distinguish ‘X00-155-1’ as a new and distinct cultivar:

1. Compact, mounded and outwardly spreading plant habit.

2. Freely branching habit.

3. Small leaf size.

4. Numerous small light violet-colored flowers with purple-colored throats.

5. Resistant to Botrytis and Powdery Mildew.

Compared to plants of the female parent, plants of the new Petunia have smaller flowers and differ in flower color. Compared to plants of the male parent, plants of the new Petunia have smaller flowers, flower earlier and differ in flower color.

Plants of the new Petunia can be compared to plants of the cultivar MP20, disclosed in U.S. Plant Pat. No. 12,857. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Petunia differed from plants of the cultivar MP20 in the following characteristics:

1. Plants of the new Petunia were more mounded and outwardly spreading than plants of the cultivar MP20.

2. Flowers of plants of the new Petunia had less prominent venation than flowers of plants of the cultivar MP20.

3. Plants of the new Petunia and the cultivar MP20 differed in flower color.

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 top of the sheet comprises a side perspective view of a typical flowering plant of ‘X 00- 155-1’ grown in a container.

The photograph at the bottom of the sheet comprises a close-up view of typical flower buds, developing flowers, open flowers and the upper and lower surfaces of typical leaves of ‘X00-155-1’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Lompoc, Calif., under commercial practice during the summer in a polycarbonate-covered greenhouse with day temperatures about 21 to 27° C., night temperatures about 16 to 18° C. and light levels about 5,000 to 9,000 foot-candles. Plants were grown with one rooted cutting per 15.25-cm container for about 11 weeks. 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.
