ABSTRACT:
BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION
Petunia hybrida
cultivar Kirimaji Double Rose.
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 Rose’.
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 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 Rose 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 Rose’. These characteristics in combination distinguish ‘Kirimaji Double Rose’ as a new and distinct cultivar of Petunia:
1. Cascading and prostrate plant habit.
2. Freely branching growth habit.
3. Early flowering habit.
4. Red purple-colored semi-double flowers with brighter red purple-colored venation.
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 Double Cascade Pink. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Petunia differed from plants of the cultivar Double Cascade Pink in the following characteristics:
1. Plants of the new Petunia were more prostrate and not as upright as plants of the cultivar Double Cascade Pink.
2. Plants of the new Petunia had slightly smaller flowers than plants of the cultivar Double Cascade Pink.
Plants of the new cultivar can be compared to plants of the cultivar Doubloon Pink 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 Pink Star in the following characteristics:
1. Plants of the new Petunia had slightly smaller flowers than plants of the cultivar Doubloon Pink Star.
2. Plants of the new Petunia had red purple-colored flowers with brighter red purple-colored venation whereas plants of the cultivar Doubloon Pink Star had light pink-colored flowers with dark purple-colored venation.
