Antirrhinum plant named ‘Sunkispinfu’

Abstract

A new and distinct cultivar of Antirrhinum plant named ‘Sunkispinfu’, characterized by its vigorous, upright and mounded plant habit; freely branching habit and short internodes; dense and bushy plant form; numerous intense pink-colored flowers streaked with red purple; long flowering period; and good garden performance.

Description

Botanical designation: Antirrhinum majus.

Cultivar denomination: ‘Sunkispinfu’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Antirrhinum, botanically known as Antirrhinum majus and hereinafter referred to by the name ‘Sunkispinfu’.

The new Antirrhinum is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new compact and freely flowering potted Antirrhinums with unique flower coloration.

The new Antirrhinum originated from a cross-pollination in Higashiomi, Shiga, Japan in May, 2003 of a proprietary selection of Antirrhinum majus identified as code number His97-2, not patented, as the female, or seed, parent with a proprietary selection of Antirrhinum majus identified as code number 02Ant33-1, not patented, as the male, or seed, parent. The new Antirrhinum was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan.

Asexual reproduction of the new Antirrhinum by cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since April, 2005, has shown that the unique features of this new Antirrhinum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Antirrhinum has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Sunkispinfu’. These characteristics in combination distinguish ‘Sunkispinfu’ as a new and distinct cultivar of Antirrhinum:

• • 1. Vigorous, upright and mounded plant habit.
  • 2. Freely branching habit and short internodes; dense and bushy plant form.
  • 3. Numerous intense pink-colored flowers streaked with red purple.
  • 4. Long flowering period.
  • 5. Good garden performance.

Plants of the new Antirrhinum differ from plants of the female parent selection primarily in flower color as plants of the female parent have white-colored flowers.

Plants of the new Antirrhinum differ from plants of the male parent selection primarily in flower color as plants of the new Antirrhinum have red purple-colored flowers.

Plants of the new Antirrhinum can be compared to plants of Antirrhinum majus ‘Sunkispinfufu’, disclosed in a U.S. Plant Patent application Ser. No. 12/157,309. Plants of the new Antirrhinum differ primarily from plants of ‘Sunkispinfufu’ in flower color as plants of ‘Sunkispinfufu’ have pale pink-colored flowers streaked with red purple.

Plants of the new Antirrhinum can also be compared to plants of Antirrhinum ‘Festa Pink’, not patented. In side-by-side comparisons, plants of the new Antirrhinum and ‘Festa Pink’ differed in the following characteristics:

• • 1. Plants of the new Antirrhinum were larger and more vigorous than plants of ‘Festa Pink’.
  • 2. Plants of the new Antirrhinum were more freely branching than plants of ‘Festa Pink’.
  • 3. Plants of the new Antirrhinum had smaller leaves than plants of ‘Festa Pink’.
  • 4. Plants of the new Antirrhinum were more freely flowering than plants of ‘Festa Pink’.
  • 5. Plants of the new Antirrhinum had larger inflorescences and flowers than plants of ‘Festa Pink’.
  • 6. Plants of the new Antirrhinum and ‘Festa Pink’ differed in flower color as plants of ‘Festa Pink’ had red purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Antirrhinum, 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 Antirrhinum.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunkispinfu’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of typical flowers of ‘Sunkispinfu’.
