ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Bracteantha plant, botanically known as
Bracteantha bracteata
and referred to by the name ‘Redbragol’.
The new Bracteantha is a product of a planned breeding program conducted by the Inventor in Redland Bay, Queensland, Australia. The objective of the program is to create and develop Bracteantha cultivars with a compact growth habit, numerous inflorescences with attractive involucral bract coloration, and long-lasting inflorescences.
The new Bracteantha originated from a cross by the Inventor of a proprietary selection of
Bracteantha bracteata
identified as code number 95-137, not patented, as the female, or seed, parent with a proprietary selection of
Bracteantha bracteata
identified as code number 95-155, not patented, as the male, or pollen, parent. The new Bracteantha was discovered and selected by the Inventor as a plant within the progeny of the stated cross in a controlled environment in Redland Bay, Queensland, Australia in 1997. The selection of the new Bracteantha was based on its bright yellow-colored involucral bracts and compact growth habit.
Asexual reproduction of the new Bracteantha by terminal cuttings taken in a controlled environment in Redland Bay, Queensland, Australia, has shown that the unique features of this new Bracteantha are stable and reproduced true to type in successive generations.
The new Bracteantha has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, light intensity, photoperiod, and water and nutritional status without, however, any variance in genotype.
The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘Redbragol’ and distinguish the new Bracteantha as a new and distinct cultivar:
1. Compact and bushy growth habit.
2. Upright, outwardly spreading and rounded plant form.
3. Freely-flowering habit.
4. Bright yellow-colored involucral bracts and orange-colored disc florets.
5. Short and strong peduncles that hold inflorescences above the foliage.
Plants of the new Bracteantha can be compard to plants of the female parent, the selection 95-137. In side-by-side comparisons conducted by the Inventor in Redland Bay, Queensland, Australia, plants of the new Bracteantha differed from plants of the selection 95-137 in the following characteristics:
1. Inflorescence shape of the new Bracteantha is star-shaped whereas inflorescence shape of the selection 95-137 is rounded.
2. Inflorescences of the new Bracteantha have fewer involucral bracts than inflorescences of the selection 95-137.
3. Inflorescences of the new Bracteantha have bright yellow-colored involucral bracts whereas inflorescences of the selection 95-137 have pink-colored involucral bracts.
Plants of the new Bracteantha can be compared to plants of the male parent, the selection 95-155. In side-by-side comparisons conducted by the Inventor in Redland Bay, Queensland, Australia, plants of the new Bracteantha differed from plants of the selection 95-155 in the following characteristics:
1. Growth habit of the new Bracteantha is compact and bushy whereas growth habit of the selection 95-155 is upright and open.
2. Plants of the new Bracteantha have larger inflorescences than plants of the selection 95-155.
3. Inflorescences of the new Bracteantha have bright yellow-colored involucral bracts whereas inflorescences of the selection 95-155 have red-colored involucral bracts.
Plants of the new Bracteantha can also be compared to plants of the cultivar Hastings Gold, not patented. In side-by-side comparisons conducted by the Inventor in Redland Bay, Queensland, Australia, plants of the new Bracteantha differed from plants of the cultivar Hastings Gold in the following characteristics:
1. Plants of the new Bracteantha are more freely flowering than plants of the cultivar Hastings Gold.
2. Plants of the new Bracteantha have larger inflorescences than plants of the cultivar Hastings Gold.
3. Plants of the new Bracteantha have shorter peduncles than plants of the cultivar Hastings Gold.
Plants of the new Bracteantha differ primarily from plants of the cultivar Redbrapin, U.S. Plant patent application Ser. No. 09/844,367, filed concurrently, in involucral coloration as plants of the cultivar Redbrapin have dark pink-colored involucral bracts.
