Abstract

A new and distinct cultivar of Osteospermum plant named ‘Tra Yelbic’, characterized by its compact plant habit; freely branching growth habit; dense and full plants; early and freely flowering habit; large daisy-type inflorescences with white-colored ray florets with yellow-colored apices; and good garden performance.

Description

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘Tra Yelbic’.

Referenced to closely-related applications: Title: Osteospermum Plant Named ‘Tra Tercot’. Applicant: Pim Kaagman. U.S. Plant pantent application Ser. No. 12/080,554: Filed concurrently with this application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis, and hereinafter referred to by the name ‘Tra Yelbic’.

The new Osteospermum is a product of a planned breeding program conducted by the Inventor in Andijk, The Netherlands. The objective of the program is to create and develop new compact Osteospermum cultivars with uniformly mounded plant habit, early and freely flowering habit and attractive ray and disc floret coloration.

The new Osteospermum originated from a cross-pollination conducted by the Inventor in Andijk, The Netherlands in June, 1999 of a proprietary selection of Osteospermum ecklonis identified as code number OZ-185-1, not patented, as the female, or seed, parent with a proprietary selection of Osteospermum ecklonis identified as code number OY-81-2, not patented, as the male, or pollen, parent. The new Osteospermum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Andijk, The Netherlands in January, 2004.

Asexual reproduction of the new Osteospermum by terminal cuttings in a controlled environment in Andijk, The Netherlands since January, 2004, has shown that the unique features of this new Osteospermum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of ‘Tra Yelbic’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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 ‘Tra Yelbic’. These characteristics in combination distinguish ‘Tra Yelbic’ as a new and distinct cultivar of Osteospermum:

• • 1. Compact plant habit.
  • 2. Freely branching growth habit; dense and full plants.
  • 3. Early and freely flowering habit.
  • 4. Large daisy-type inflorescences with white-colored ray florets with yellow-colored apices.
  • 5. Good garden performance.

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

• • 1. Plants of the new Osteospermum are more freely branching than plants of the female parent selection.
  • 2. Inflorescences of plants of the new Osteospermum are flatter and more open than inflorescences of plants of the female parent selection.
  • 3. Plants of the new Osteospermum and the female parent selection differ in ray floret color as ray florets of plants of the female parent selection are lemon yellow in color.

Plants of the new Osteospermum differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Osteospermum are more compact than plants of the male parent selection.
  • 2. Plants of the new Osteospermum has larger inflorescences than plants of the male parent selection.
  • 3. Plants of the new Osteospermum and the male parent selection differ in ray floret color as ray florets of plants of the male parent selection are purple in color.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ‘Tra Tercot’, U.S. Plant patent application Ser. No. 12/080,554 filed concurrently. Plants of the new Osteospermum differ primarily from plants of ‘Tra Tercot’ in ray floret color as plants of ‘Tra Tercot’ have salmon-colored ray florets. In addition, plants of the new Osteospermum have larger leaves than plants of ‘Tra Tercot’.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ‘Sunny Amanda’, disclosed in U.S. Plant Pat. No. 16,522. In side-by-side comparisons conducted in Hillscheid, Germany, plants of the new Osteospermum differed from plants of ‘Sunny Amanda’ in the following characteristics:

• • 1. Plants of the new Osteospermum were more freely branching than plants of ‘Sunny Amanda’.
  • 2. Plants of the new Osteospermum flowered earlier than plants of ‘Sunny Amanda’.
  • 3. Plants of the new Osteospermum had shorter peduncles than plants of ‘Sunny Amanda’.
