ABSTRACT:
BOTANICAL CLASSIFICATION/CULTIVAR DENOMINATION
Euphorbia pulcherrima
Willd. cultivar KLEW01064.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as
Euphorbia pulcherrima
Willd., and hereinafter referred to by the name ‘KLEW01064’.
The new Poinsettia is a product of a planned breeding program conducted by the Inventor in Stuttgart, Germany. The objective of the breeding program is to create new Poinsettia cultivars with attractive flower bract coloration and uniform plant habit.
The new Poinsettia originated from a cross made by the Inventor in 1996 of a proprietary selection of
Euphorbia pulcherrima
Willd. identified as code number K 72, not patented, as the female, or seed, parent, with a proprietary selection of
Euphorbia pulcherrima
Willd. identified as code number L52, not patented, as the male, or pollen, parent. The cultivar KLEW01064 was discovered and selected by the Inventor in 1998 as a flowering plant within the progeny of the stated cross in a controlled environment in Stuttgart, Germany. The selection of this plant was based on its attractive flower bract coloration and uniform plant habit.
Asexual reproduction of the new Poinsettia by vegetative terminal cuttings taken at Stuttgart, Germany since 1999, has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KLEW01064’. These characteristics in combination distinguish ‘KLEW01064’ as a new and distinct Poinsettia cultivar:
1. Upright and uniform plant habit.
2. Dark green-colored leaves with purple-colored petioles.
3. Bright red-colored flower bracts.
4. Very early flowering; response time, about 6.5 weeks.
5. Good post-production longevity.
Plants of the new Poinsettia differ from plants of the female parent, the selection K 72, in the following characteristics:
1. Plants of the new Poinsettia are not as vigorous as plants of the selection K 72.
2. Leaves of plants of the new Poinsettia are more lobed than leaves of plants of the selection K 72.
3. Plants of the new Poinsettia have lighter red-colored flower bracts than plants of the selection K 72.
Plants of the new Poinsettia differ from plants of the male parent, the selection L 52, in the following chracteristics:
1. Plants of the new Poinsettia have darker green leaves than plants of the selection L 52.
2. Plants of the new Poinsettia have narrower leaves than plants of the selection L 52.
Plants of the new Poinsettia can also be compared to plants of the cultivar Fisson, disclosed in U.S. Plant Pat. No. 9,365. In side-by-side comparisions conducted in Stuttgart, Germany, plants of the new Poinsettia differed from plants of the cultivar Fisson in the following characteristics:
1. Plants of the new Poinsettia were more vigorous than plants of the cultivar Fisson.
2. Plants of the new Poinsettia flowered about one week earlier than plants of the cultivar Fisson.
