plant named ‘Sunjiraliki’

Abstract

A new and distinct cultivar of Begonia plant named ‘Sunjiraliki’, characterized by its compact, outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; and numerous single light yellow-colored flowers that are held above and beyond the foliar plane.

Description

Botanical designation: Begonia×tuberhybrida.

Cultivar denomination: ‘SUNJIRALIKI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia×tuberhybrida and hereinafter referred to by the name ‘Sunjiraliki’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Narusawa-mura, Minamituru-gun, Yamanashi, Japan. The objective of the breeding program is to create new compact and freely branching Begonia plants with a mounding plant habit and attractive leaf and flower coloration.

The new Begonia plant originated from a cross-pollination made by the Inventor in Narusawa-mura, Minamituru-gun, Yamanashi, Japan in June, 2007 of a proprietary selection of Begonia×tuberhybrida identified as code number FC04Y314N, not patented, as the female, or seed, parent with a proprietary selection of Begonia×tuberhybrida identified as code number FC04Y322N, not patented, as the male, or pollen, parent. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Narusawa-mura, Minamituru-gun, Yamanashi, Japan in July, 2008.

Asexual reproduction of the new Begonia plant by cuttings taken in a controlled greenhouse environment in Narusawa-mura, Minamituru-gun, Yamanashi, Japan since July, 2008 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Sunjiraliki’. These characteristics in combination distinguish ‘Sunjiraliki’ as a new and distinct Begonia plant:

• • 1. Compact, outwardly spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Numerous single light yellow-colored flowers that are held above and beyond the foliar plane.

Plants of the new Begonia differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Begonia have smaller leaves than plants of the female parent selection.
  • 2. Plants of the new Begonia have smaller male flowers than plants of the female parent selection.

Plants of the new Begonia differ primarily from plants of the male parent selection in plant height as plants of the new Begonia are more compact than plants of the male parent selection.

Plants of the new Begonia can be compared to plants of Begonia×tuberhybrida ‘Firecracker Orange’, not patented. In side-by-side comparisons conducted in Narusawa-mura, Minamituru-gun, Yamanashi, Japan, plants of the new Begonia differed primarily from plants of ‘Firecracker Orange’ in the following characteristics:

• • 1. Plants of the new Begonia were more compact than plants of ‘Firecracker Orange’.
  • 2. Plants of the new Begonia had slightly shorter internodes than plants of ‘Firecracker Orange’.
  • 3. Plants of the new Begonia had shorter leaves and leaf petioles than plants of ‘Firecracker Orange’.
  • 4. Plants of the new Begonia and ‘Firecracker Orange’ differed in leaf and leaf petiole color.
  • 5. Plants of the new Begonia were more freely flowering than plants of ‘Firecracker Orange’.
  • 6. Plants of the new Begonia had smaller male and female flowers than plants of ‘Firecracker Orange’.
  • 7. Plants of the new Begonia and ‘Firecracker Orange’ differed in flower color as plants of ‘Firecracker Orange’ had orange red-colored flowers.
  • 8. Plants of the new Begonia had shorter peduncles than plants of ‘Firecracker Orange’.
