Poinsettia plant named ‘Doeuprerib’

Botanical designation:Willd.

Cultivar denomination: ‘DOEUPRERIB’.

The present invention relates to a new and distinct cultivar of Poinsettia plant, botanically known asWilld., and hereinafter referred to by the cultivar name ‘Doeuprerib’.

The new Poinsettia plant is a product of a planned breeding program conducted by the Inventor in Encinitas, California. The objective of the breeding program is to create new uniform and early-flowering Poinsettia plants having large inflorescences with attractive flower bracts and excellent post-production longevity.

The new Poinsettia plant originated from a cross-pollination made by the Inventor in November 2017 of a proprietary selection ofWilld. identified as code number EZ14-000251-001 (PE15-52), not patented, as the female, or seed, parent, with a proprietary selection ofWilld. identified as code number EZ15-000116-001 (16-56), not patented, as the male, or pollen, parent. The new Poinsettia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Encinitas, California on Dec. 24, 2018.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, California since March 2019 has shown that the unique features of this new Poinsettia plant are stable and reproduced true to type in successive generations of asexual reproduction.

Plants of the new Poinsettia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Doeuprerib’. These characteristics in combination distinguish ‘Doeuprerib’ as a new and distinct Poinsettia plant:

In side-by-side comparisons conducted in Encinitas, California, plants of the new Poinsettia differ primarily from plants of the female parent selection in the following characteristics:

In side-by-side comparisons conducted in Encinitas, California, plants of the new Poinsettia differ primarily from plants of the male parent selection in the following characteristics:

Plants of the new Poinsettia can be compared to plants of theWilld. ‘Peterstar’, disclosed in U.S. Plant Pat. No. 8,259. In side-by-side comparisons, plants of the new Poinsettia differ primarily from plants of ‘Peterstar’ in the following characteristics:

Plants of the new Poinsettia can be compared to plants of theWilld. ‘490’, disclosed in U.S. Plant Pat. No. 7,825. In side-by-side comparisons, plants of the new Poinsettia differ primarily from plants of ‘490’ in the following characteristics:

Plants used in the aforementioned photographs and in the following detailed description were grown during the summer to late autumn in 16.5-cm containers in a polyethylene-covered greenhouse in Encinitas, California under natural season conditions and cultural practices typical of commercial Poinsettia production. During the production of the plants, day temperatures averaged 21° C., night temperatures ranged from 13° to 14° C. and light levels ranged from 3,500 to 4,500 foot-candles. Plants were pinched one time about six weeks after sticking unrooted cuttings and plants were 22 weeks old when the photographs and the description were taken. Measurements and numerical values represent averages for typical flowering plants. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
