Description

Botanical denomination: Euphorbia pulcherrima Willd.

Cultivar designation: ‘Alreddy Red’.

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 cultivar name ‘Alreddy Red’.

The new Poinsettia is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program is to create new Poinsettia cultivars with upright and uniform plant habit, attractive flower bract shape and coloration, low temperature tolerance and good postproduction longevity.

The new Poinsettia originated from a cross-pollination made by the Inventor on Jan. 15, 2000 of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number 98026, not patented, as the female, or seed, parent, with a proprietary selection of Euphorbia pulcherrima Willd. identified as code number 98013, not patented, as the male, or pollen, parent. The cultivar Alreddy Red was discovered and selected by the Inventor on Nov. 16, 2000 as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Aalsmeer, The Netherlands.

Asexual reproduction of the new Poinsettia by vegetative terminal cuttings in a controlled environment in Aalsmeer, The Netherlands since July, 2001, 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 ‘Alreddy Red’. These characteristics in combination distinguish ‘Alreddy Red’ as a new and distinct Poinsettia cultivar:

    • 1. Upright and uniform plant habit.
    • 2. Strong sturdy stems.
    • 3. Dark green-colored leaves.
    • 4. Dark red-colored flower bracts.
    • 5. Early flowering habit; response time, about seven weeks.
    • 6. Excellent post-production longevity.
    • 7. Relatively tolerant to low temperatures.

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

    • 1. Plants of the new Poinsettia have smaller and darker red-colored flower bracts than plants of the female parent selection.
    • 2. Plants of the new Poinsettia are tolerant to lower temperatures than plants of the female parent selection.

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

    • 1. Plants of the new Poinsettia have longer postproduction longevity than plants of the male parent selection.
    • 2. Plants of the new Poinsettia are tolerant to lower temperatures than plants of the male parent selection.

Plants of the new Poinsettia can be compared to plants of the cultivar Fiscor, disclosed in U.S. Plant Pat. No. 9,364. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Poinsettia differed from plants of the cultivar Fiscor in the following characteristics:

    • 1. Plants of the new Poinsettia had stronger stems and were sturdier than plants of the cultivar Fiscor.
    • 2. Flower bract color of plants of the new Poinsettia was darker red than flower bract color of plants of the cultivar Fiscor.
    • 3. Plants of the new Poinsettia are tolerant to lower temperatures than plants of the cultivar Fiscor.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Poinsettia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Poinsettia. The photograph comprises a side perspective view of a single flowering plant of ‘Alreddy Red’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants of the new Poinsettia 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 aforementioned photograph, following observations and measurements describe plants grown in De Kwakel, The Netherlands during the fall under commercial practice in a glass-covered greenhouse with day and night temperatures averaging the first ten weeks at 20° C.; day and night temperatures averaging the last weeks of production at 17° C.; and light levels of about 200 W/m2. Cuttings were planted into 13-cm containers when rooted and pinched once. Plants were flowered under short day/long night (15 hour nyctoperiods) conditions. Plants were about 17 to 18 weeks from unrooted cuttings when the photograph and the detailed botanical description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
