ABSTRACT:

Botanical classification cultivar designation:
Calibrachoa pygmaea×Calibrachoa parviflora
cultivar Kirifu Compact Blue.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as
Calibrachoa pygmaea×Calibrachoa parviflora
, and hereinafter referred to by the name ‘Kirifu Compact Blue’.
The new Calibrachoa 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 Calibrachoa cultivars with small leaves and flowers.
The new Calibrachoa originated from a cross-pollination made by the Inventors in April, 1995, in Tochigi, Japan, of an unnamed proprietary selection of
Calibrachoa pygmaea
, not patented, as the female, or seed, parent with an unnamed proprietary selection of
Calibrachoa parviflora
, not patented, as the male, or pollen, parent. The new Calibrachoa 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 September, 1996.
Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Saitama-ken, Japan, since March, 1997, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Kirifu Compact Blue 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 ‘Kirifu Compact Blue’. These characteristics in combination distinguish ‘Kirifu Compact Blue’ as a new and distinct cultivar of Calibrachoa:
1. Spreading and prostrate plant habit.
2. Freely branching growth habit.
3. Short internodes giving a dense bushy appearance.
4. Small leaves.
5. Early and freely flowering habit.
6. Small pale violet-colored flowers.
7. Good weather tolerance.
Plants of the new Calibrachoa can be compared to plants of the female parent, an unnamed proprietary selection of
Calibrachoa pygmaea
. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Calibrachoa differed from plants of the female parent in the following characteristics:
1. Flowers of plants of the new Calibrachoa were smaller than flowers of plants of the female parent.
2. Flowers of plants of the new Calibrachoa were pale violet in color whereas flowers of plants of the female parent were white in color.
3. Flowers of plants of the new Calibrachoa produced very little pollen whereas flowers of plants of the female parent produced abundant pollen.
Plants of the new Calibrachoa can be compared to plants of the male parent, an unnamed proprietary selection of
Calibrachoa parviflora
. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Calibrachoa differed from plants of the male parent in the following characteristics:
1. Flowers of plants of the new Calibrachoa were smaller than flowers of plants of the male parent.
2. Flowers of plants of the new Calibrachoa were pale violet in color whereas flowers of plants of the male parent were purple in color.
Plants of the new Calibrachoa differ primarily from plants of the Calibrachoa cultivars Kirifu Blue, disclosed in a U.S. Plant patent application Ser. No. 10/122,734 filed concurrently, Kirifu Red, disclosed in a U.S. Plant patent application Ser. No. 10/122,690 filed concurrently, and Kirifu Compact Red, disclosed in a U.S. Plant patent application Ser. No. 10/122,688 filed concurrently, primarily in flower coloration and plant size.
Plants of the new cultivar can be compared to plants of the cultivar Liricashower Pink, not patented. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Calibrachoa differed from plants of the cultivar Liricashower Pink in the following characteristics:
1. Plants of the new Calibrachoa were not as tall and broad as plants of the cultivar Liricashower Pink.
2. Flowers of plants of the new Calibrachoa were smaller than flowers of plants of the cultivar Liricashower Pink.
3. Flowers of plants of the new Calibrachoa were pale violet in color whereas flowers of plants of the cultivar Liricashower Pink were red purple in color.
