Abstract
A Chrysanthemum plant named Bright Tracy particularly characterized by its flat capitulum form; daisy capitulum type, with 4 to 6 layers of ray florets; yellow ray floret color; diameter across face of capitulum of 54 to 70 mm when fully opened; branching pattern is spreading and prolific; natural season flower date of August 27 to 29 when planting rooted cuttings on June 17 to 21 in Salinas, Calif., and of September 23 to 28 when planted rooted cuttings June 15 to 18 in Hightstown, N.J.; plant height of 20 to 33 cm when grown in fall under natural daylength with no growth regulators; and durable, uniform performance.
Description
The present invention comprises a new and distinct cultivar of Chrysanthemum, botanically known as Dendranthema grandiflora, and referred to by the cultivar name Bright Tracy.
Bright Tracy, identified as 9618 (85-095A01), is a product of a mutation induction program. The new cultivar was discovered and selected by inventor Leon Glicenstein on Apr. 9, 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 2000 rads in Fort Myers, Fla. on Oct. 24, 1991. The irradiated parent cultivar was the cultivar Tracy, disclosed in U.S. Plant Pat. No. 8,609 and described as a daisy garden mum with white flower color.
The irradiation program resulting in Bright Tracy had as its primary objective the expansion of color ranges of the parent cultivar Tracy. The irradiation program comprised irradiation of cuttings of the parent cultivar at irradiation levels of 1500, 1750 and 2000 rads. A total of 1101 cuttings harvested from a total of 225 irradiated plants were planted on Feb. 24, 10 and 3, 1992, respectively. Of these, 9 initial selections were made, which selections were then revegetated and reflowered. Three consecutive flowerings resulted in discarding 7 of the original 9 selections on Dec. 16, 1992. The remaining selections were maintained as PIs (Possible Introductions) and further trialed in Salinas, Calif., Hightstown, N.J. and Leamington, Ontario, Canada, ultimately resulting in the decision to introduce one selection as Bright Tracy, and the other selection as Dreamy Tracy, disclosed in pending application Ser. No. 08/516,564.
The first act of asexual reproduction of Bright Tracy was accomplished when vegetative cuttings were taken from the initial selection in June of 1992 in a controlled environment in Salinas, Calif., by technicians working under supervision of Leon Glicenstein.
Horticultural examination of controlled flowerings of successive plantings has shown that the unique combination of characteristics as herein disclosed for Bright Tracy are firmly fixed and are retained through successive generations of asexual reproduction.
Bright Tracy 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 controlled open areas in Salinas, Calif., and in Hightstown, N.J. Rooted cuttings were established in soil and maintained outdoors under the natural temperature and daylength prevailing during June through October.
The following traits have been repeatedly observed and are determined to be basic characteristics of Bright Tracy, which, in combination, distinguish this Chrysanthemum as a new and distinct cultivar:
1. Flat capitulum form.
2. Daisy capitulum type, with 4 to 6 layers of ray florets.
3. Yellow ray floret color.
4. Diameter across face of capitulum of 54 to 70 mm when fully opened.
5. Branching pattern is spreading and prolific.
6. Natural season flower date of August 27 to 29 when planting rooted cuttings on June 17 to 21 in Salinas, Calif., and of September 23 to 28 when planting rooted cuttings June 15 to 18 in Hightstown, N.J.
7. Plant height of 20 to 33 cm when grown in fall under natural daylength with no growth regulators.
8. Durable, uniform performance.
The accompanying photographic drawing is a color photograph of Bright Tracy grown as a pinched garden mum under natural season outside conditions in Salinas, Calif., with the colors being as nearly true as possible with illustrations of this type. Plants were grown outside and dug and transplanted into 15 cm pots at flowering time for photography purposes.
Of the commercial cultivars known to the inventor, the most similar in comparison to Bright Tracy is the parent cultivar Tracy. All traits of Bright Tracy are similar to those of Tracy, except for the ray floret color. The ray floret color of Bright Tracy is yellow (5A to 5B, fading to 5C), while the ray floret color of Tracy is white. In comparison to sibling cultivar Dreamy Tracy, the latter consistently flowers 3-7 days earlier, has a slightly shorter plant height by 2-4 cm, and has a different ray floret color.
