Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Petunia hybrida cultivar Kirimaji Double Capricious.

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 Capricious’.

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 Petunia selection, not patented, as the female, or seed, parent with the Petunia cultivar Sonata Pure White, 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 Capricious 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 Capricious’. These characteristics in combination distinguish ‘Kirimaji Double Capricious’ as a new and distinct cultivar of Petunia:

1. Cascading and prostrate plant habit.

2. Freely branching growth habit.

3. Early flowering habit.

4. Light purple-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, an 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 and color as plants of the female parent had white-colored single flowers.

Plants of the new Petunia can be compared to plants of the male parent, the cultivar Sonata Pure White. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Petunia differed from plants of the cultivar Sonata Pure White in the following characteristics:

1. Plants of the new Petunia were more prostrate and not as upright as plants of the cultivar Sonata Pure White.

2. Plants of the new Petunia had slightly smaller flowers than plants of the cultivar Sonata Pure White.

3. Plants of the new Petunia had light purple-colored flowers whereas plants of the cultivar Sonata Pure White had white-colored flowers.

Plants of the new cultivar can also be compared to plants of the cultivar Surfinia Super Double Blue Vein, 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 Surfinia Super Double Blue Vein in the following characteristics:

1. Plants of the new Petunia had slightly smaller flowers than plants of the cultivar Surfinia Super Double Blue Vein.

2. Plants of the new Petunia had light purple-colored flowers whereas plants of the cultivar Surfinia Super Double Blue Vein had bright purple-colored flowers with dark red purple-colored venation.

Plants of the new cultivar can also be compared to plants of the cultivar Doubloon Lilac 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 Lilac Star in the following characteristics:

1. Plants of the new Petunia had slightly smaller flowers than plants of the cultivar Doubloon Lilac Star.

2. Plants of the new Petunia had light purple-colored flowers whereas plants of the cultivar Doubloon Lilac Star had light purple-colored flowers with dark purple-colored venation.

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. Twenty-centimeter containers with three plants per container were used for the aforementioned photographs and the following description. Plants were grown under conditions which closely approximate commercial production conditions during the winter in Santa Paula, Calif. in a polyethylene-covered greenhouse. Plants used for the photographs and the description were about 14 weeks from planting rooted young plants. During the production period, day temperatures averaged 28° C., night temperatures averaged 21° C., and light levels were about 5,000 footcandles.
