ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as
Osteospermum ecklonis
and referred to by the cultivar name Dondo.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Aabyhoj, Denmark. The objective of the breeding program was to create new Osteospermum cultivars with interesting ray floret colors.
The new cultivar originated from a cross made by the Inventor in 1995 of proprietary selection of
Osteospermum ecklonis
identified as 949343 as the female, or seed, parent and a proprietary selection of
Osteospermum ecklonis
identified as 949322 as the male, or pollen, parent. The new Osteospermum was selected by the Inventor as a flowering plant within the progeny of this cross in a controlled environment in Aabyhoj, Denmark, in 1996.
Plants of the new cultivar are different from plants of the female parent, the selection 949343, in inflorescence size and quantity of ray florets.
Plants of the new Osteospermum are different from plants of the male parent, the selection 949322, in plant habit inflorescence size and quantity of ray florets.
Asexual propagation of the new cultivar by terminal cutting at Aabyhoj, has shown that the unique features of this new Osteospermum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dondo’. These characteristics in combination distinguish ‘Dondo’ as a new and distinct cultivar:
1. Upright and outwardly spreading plant habit.
2. Numerous inflorescences per plant.
3. Pink ray florets with blue disc florets.
4. Tolerance to high temperatures.
The new cultivar can be compared to the Osteospermum cultivar Cape Daisy Congo, disclosed in U.S. Plant Pat. No. 10,342. In side-by-side comparisons conducted in Aabyhoj, Denmark, and Encinitas, Calif., plants of the new cultivar are smaller and less vigorous; are less freely branching; have smaller inflorescences; have darker red purple ray florets that resist fading better; and are more high temperature tolerant than plants of the cultivar Cape Daisy Congo.
The cultivar Dondo has 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.
