Abstract

A distinct cultivar of Petunia plant named ‘Kirimaji Double White’, characterized by its low mounding cascading to prostrate plant habit; freely branching growth habit; early and freely flowering habit; white-colored semi-double flowers; and good weather tolerance.

Description

Botanical classification/cultivar designation: Petunia hybrida cultivar Kirimaji Double White.
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 ‘Kirimaji Double White’.
The new Petunia is a product of a planned breeding program conducted by the Inventors in Tochigi, Japan. The objective of the breeding program is to create new double Petunia cultivars that have stronger growth and attractive flower coloration.
The new Petunia originated from a cross-pollination made by the Inventors in March, 1999, in Tochigi, Japan, of an unnamed proprietary selection of Petunia, not patented, as the female, or seed, parent with the Petunia cultivar Double Cascade Pink, not patented, as the male, or pollen, parent. The new Petunia was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Tochigi, Japan, in July, 2000. The selection of this plant was based on its strong plant growth habit and attractive flower coloration.
Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Tochigi, Japan, since July, 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 Kirimaji Double White 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 ‘Kirimaji Double White’. These characteristics in combination distinguish ‘Kirimaji Double White’ as a new and distinct cultivar of Petunia:
1. Low mounding cascading to prostrate plant habit.
2. Freely branching growth habit.
3. Early and freely flowering habit.
4. White-colored semi-double flowers.
5. Good weather tolerance; tolerant to wind, rain, and low and high temperatures.
Plants of the new Petunia can be compared to plants of the female parent, the unnamed proprietary Petunia selection. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Petunia differed from plants of the female parent primarily in flower form as plants of the female parent had single flowers.
Plants of the new Petunia can be compared to plants of the male parent, the cultivar Double Cascade Pink. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Petunia were not as upright and had slightly smaller flowers than plants of the cultivar Double Cascade Pink. In addition, plants of the cultivar Double Cascade Pink had pink-colored flowers.
Plants of the new cultivar can be compared to plants of the cultivar Doubloon White Star, not patented. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Petunia differed from plants of the cultivar Doubloon White Star in the following characteristics:
1. Plants of the new Petunia had slightly smaller flowers than plants of the cultivar Doubloon White Star.
2. Petal apices of plants of the new Petunia were somewhat rounded whereas petal apices of plants of the cultivar Doubloon White Star were pointed.
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 photograph 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 ‘Kirimaji Double White’. The photograph on the second sheet comprises a close-up view of a typical flower of ‘Kirimaji Double White’.
DETAILED BOTANICAL DESCRIPTION
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. Plants used for the aforementioned photographs and the following description were grown in containers and under conditions which closely approximate commercial production conditions during the spring in Santa Paula, Calif. in a polyethylene-covered greenhouse. Plants used for the photographs and the description were about nine weeks from planting rooted young plants. During the production period, day temperatures ranged from 20 to 35° C., night temperatures ranged from 10 to 20° C., and light levels ranged from 20 to 40 klux.
