The present invention comprises a new and distinct cultivar of Chrysanthemum, botanically known as Dendranthema grandiflora, and referred to by the cultivar name Sweet Cherie.
Sweet Cherie, identified as 4234 (89-114A03) is a product of a mutation induction program. The new cultivar was discovered and selected by Susan M. Polys on Jan. 13, 1992, in a controlled environment in Salinas, Calif., as one flowering plant within a flowering block established as rooted cuttings from stock plants which had been exposed as unrooted cuttings to an X-ray source of 1500 rads in Fort Myers, Fla., on May 23, 1991. The irradiated parent cultivar was an unnamed proprietary seedling identified as 4207 (89-114003), and described as a daisy spray pot mum with a flat capitulum form; a very light pink ray floret color; diameter across face of capitulum of 32 to 48 mm when fully opened, flowering response period of 49 to 56 days after start of short days; plant height of 18 to 25 cm with 0 to 1 applications of 2500 ppm B-9 SP when grown as a pinched pot mum in a 15 cm pot; and spreading and prolific branching pattern, with 6 to 8 laterals after pinch. The parent cultivar has not been sold or offered for sale, or otherwise publicly disclosed.
The irradiation program resulting in Sweet Cherie had as its primary objective the expansion of the color range of the parent seedling 4207, with the ray floret color of the parent considered to be too light for commercial introduction, while all other characteristics of the parent were considered to be excellent. The irradiation program comprised irradiating cuttings of the parent cultivar at irradiation levels of 1500, 1750 and 2000 rads. A total of 2470 cuttings harvested from a total of 225 irradiated plants were planted on Sep. 9, 1991. Of these, 37 initial selections were made, which selections were then revegetated and reflowered. Three consecutive flowerings resulted in discarding 32 of the original 37 selections on Jul. 1, 1992. Five selections were retained and reflowered again, ultimately resulting in the decision to introduce all remaining selections as Sweet Cherie, Dark Cherie, Honey Cherie, Soft Cherie and Sunny Cherie. Applications are pending for the other induced mutations.
The first act of asexual reproduction of Sweet Cherie was accomplished when vegetative cuttings were taken from the initial selection in March 1992 in a controlled environment in Salinas, Calif., by technicians working under supervision of Susan M. Polys.
Horticultural examination of controlled flowerings of successive plantings has shown that the unique combination of characteristics as herein disclosed for Swewet Cherie are firmly fixed and are retained through successive generations of asexual reproduction.
Sweet Cherie 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, however, any variance in genotype.
The following observations, measurements and comparisons describe plants grown in Salinas, Calif. under greenhouse conditions which approximate those generally used in commercial greenhouse practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Sweet Cherie, which, in combination, distinguish this Chrysanthemum as a new and distinct cultivar:
1. Flat capitulum form.
2. Daisy capitulum type.
3. White ray floret color, with pinking buds and pink overcast of the underside of the ray florets.
4. Diameter across face of capitulum of 35 to 44 mm when fully opened, when grown as a pinched spray pot mum.
5. Very floriferous, with excellent display of many small flowers.
6. Photoperiodic flowering response of 50 to 53 days after start of short days.
7. Plant height, with 13 to 14 long days after sticking unrooted cuttings and with 0 to 1 applications of 2500 ppm B-9 SP, ranges from 20 to 28 cm when grown as a pinched pot mum with 4 cuttings in a 15 cm pot.
8. Branching pattern is spreading and prolific, each plant having 7 to 9 laterals after pinch.
9. Recommended as a spray pot mum.
The accompanying photographic drawings show typical inflorescence and leaf characteristics of Sweet Cherie, with the colors being as nearly true as possible with illustrations of this type.
Sheet 1 is a color photographic of a potted mum of Sweet Cherie, with 4 cuttings in a 15 cm pot.
Sheet 2 is a black and white photograph showing the upper and under sides of the leaves of the Cherie series at three stages of development (mature, intermediate and immature). In sheet 2 a measuring tape in centimeters has been added.
Of the commercial cultivars known to the inventor, the most similar in comparison to Sweet Cherie is the cultivar identified as Chantal, disclosed in U.S. Plant Pat. No. 7,516. Reference is made to attached Chart A, which compares certain characteristics of Sweet Cherie with the same characteristics of Chantal.
Similar traits are capitulum form and type, branching pattern, and recommendation as a spray pot mum. Sweet Cherie exhibits pinking of buds and a pink overcast of the underside of the ray florets, while the ray floret color of Chantal is clear white. Sweet Cherie has a larger diameter of capitulum than Chantal, a slower flowering response, and a taller plant height, requiring less long days to reach a commercially acceptable height than Chantal. The range of meaurements of Chantal is much wider than the range of measurements of Sweet Cherie, based on the fact that Chantal has been tested for many years, while Sweet Cherie has been tested for only nine months at the time of the application.
When compared with the parent seedling, all traits of Sweet Cherie are similar to those of the parent, except for the color of the ray florets. When comparing the description of Sweet Cherie with the description of the parent, it is evident that the parent seedling has a much wider range of measurements than Sweet Cherie. This is also based on evaluations over a long time period for the parent in comparison with the short time period that Sweet Cherie has been tested.
In the following description color references are made to The Royal Horticultural Society Color Chart. The color values were determined on plant material grow as a pinched spray pot mum in Salinas, Calif. on Feb. 23, 1993.
