Abstract
A new and distinct cultivar of Poinsettia plant named ‘Fiscor Dark Red’ characterized by having dark-red bract color; medium-sized, almost flat inflorescence with weakly lobed bracts; intense dark-green foliage with slight dentation; compact and wide, lowly molded plant habit; medium to late flowering response; and relatively good keeping quality of bracts and foliage.
Description
The present invention relates to a new and distinct cultivar of poinsettia plant known by the cultivar name ‘Fiscor Dark Red’ and botanically known as Euphorbia pulcherrima.
‘Fiscor Dark Red’ is a product of a mutation induction program carried out by the inventor, Katharina Zerr, in Hillscheid, Germany, in 1994. The primary objective of the induction program was to expand the bract color ranges of ‘Fiscor’ (U.S. Plant Pat. No. 9,364). ‘Fiscor’ is characterized by its relatively dark red-colored bracts, dark-green foliage and comparatively compact plant habit.
The irradiation program comprised exposing rooted cuttings taken from plants of the parent cultivar to an X-ray source of 30 Gy dosage in Ahrensburg, Germany, under the supervision of the inventor. The irradiated plants were grown out in a greenhouse in Hillscheid, Germany, and were asexually propagated by the inventor by taking cuttings. The plants resulting from these cuttings were screened for mutations as small, flowering, single-stem plants beginning in fall of 1994. The mutations discovered were identified by numbers. Parts of plants exhibiting a mutation of interest were left to develop vegetative shoots which were used as cuttings and grown out.
‘Fiscor Dark Red’ originated from a single plant (no. 222) having a distinctly darker-red bract color, which was discovered in the spring of 1995. This plant, which appeared to be completely mutated, was propagated vegetatively by taking cuttings, and the off-spring were screened for uniformity in the spring of 1996 prior to further propagation. The clone was examined more closely in autumn of 1997, and again in the late summer and autumn of 1998 in Hillscheid, Germany. Horticultural examination of the clone starting in 1997 and continuing thereafter has confirmed that the combination of characteristics as herein disclosed for ‘Fiscor Dark Red’ are firmly fixed and retained through successive generations of asexual reproduction.
The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fiscor Dark Red’ which in combination distinguish this Poinsettia as a new and distinct cultivar:
1. Dark-red bract color;
2. Medium-sized, almost flat inflorescence with weakly lobed bracts;
3. Intense dark-green foliage with slight dentation;
4. Compact and wide, lowly molded plant habit;
5. Medium to late flowering response; and
6. Relatively good keeping quality of bracts and foliage.
‘Fiscor Dark Red’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and daylength without any change in genotype. The following observations, measurements and comparisons describe plants grown in Langley, British Columbia, Canada, under greenhouse conditions which approximate those generally used in commercial practice.
Of the many commercial cultivars known to the inventor, the most similar in comparison to ‘Fiscor Dark Red’ are the parent cultivar ‘Fiscor’ and the co-pending cultivar ‘Fisson Dark Red’ (U.S. Plant patent application Ser. No. 09/496,459). In comparison to ‘Fiscor’, ‘Fiscor Dark Red’ has a considerably darker red bract color, slightly narrower bracts and leaves, and even more intense anthocyanin coloration of stems and petioles.
In comparison to ‘Fisson Dark Red’, ‘Fiscor Dark Red’ has differently shaped inflorescence with flat, not folded, and relatively smooth-surfaced bracts. ‘Fiscor Dark Red’ has a wider but shorter plant habit than ‘Fisson Dark Red’.
The accompanying color photographic illustration shows typical inflorescence and foliage of a mature potted plant of ‘Fiscor Dark Red’, with colors being as true as possible with illustrations of this type.
The plants described were grown in a greenhouse in Langley, British Columbis, Canada, in the fall of 1998. Rooted cuttings were planted into 15-cm pots (in diameter) on August 10, and were pinched on August 20, leaving 8 nodes. The minimum temperature was 23° C. until October 10, 20° C. to mid-November, and lower thereafter. The plants initiated flowers under natural short-day conditions in the fall. The following measurements were made on Nov. 24-25, 1998, 15 weeks after planting of rooting cuttings. Additional observations were made in Hillscheid, Germany, in early December using 17 week old plants of similar size.
Observations and measurements were mainly taken at the beginning of flowering. In the following description, color references are made to The Royal Horticultural Society (R.H.S.) Color Chart. The color values were determined indoors in a north light.
