Description

The present invention comprises a new and distinct cultivar of Chrysanthemum, botanically known as Dendranthema grandiflora, and referred to by the cultivar name Lemon Tayrona.
Lemon Tayrona, identified as 0804 (85-249G04), is a product of a mutation induction program. The new cultivar was discovered and selected by Cornelis P. VandenBerg on Sep. 4, 1990 as a reselection of an irradiation selection identified as 0614, which was selected on Nov. 13, 1989 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 11, 1989. The irradiated parent cultivar was the cultivar identified as Tayrona, disclosed in U.S. Plant Pat. No. 7,482. Tayrona is described as a decorative spray cut mum with a flat capitulum form; a white ray floret color with a fresh green center of the flower; diameter across face of capitulum of 63 to 73 mm when fully opened; flowering response period of 50 to 57 days after start of short days in Salinas, Calif., and of 64 to 68 days in Bogota, Colombia; plant height of 74 to 86 cm when grown in Salinas with 6 to 11 long days prior to start of short days, and of 97 to 119 cm when grown in Bogota with 14 to 15 long days prior to start of short days; and excellent tolerance to low night temperatures for bud initiation and flower development. The above description of Tayrona has a wider range of measurements than the description of Tayrona in U.S. Plant Pat. No. 7,482. This is based on the continued flowering trials of Tayrona after preparing the plant patent application for Tayrona. Tayrona was commercially introduced in July 1990.
The irradiation program resulting in Lemon Tayrona had as its primary objective the expansion of color ranges of the parent cultivar Tayrona. The irradiation program comprised irradiating cuttings of the parent cultivar at irradiation levels of 1500, 1750 and 2000 rads. A total of 1198 cuttings harvested from a total of 225 irradiated plants were planted on Sep. 11, 1989, Sep. 4, 1989 and Aug. 21, 1989 for plants irradiated at 1500 rads, 1750 rads and 2000 rads, respectively. Of these, 16 initial selections were made, which selections were then revegetated and reflowered. Four consecutive flowerings resulted in discarding 12 of the original 16 selections on Sep. 4, 1990. Three codes (plants) were reselected prior to discarding on the same date, while four codes were retained as PI (Possible Introduction) status. The four retained codes and the three reselections were tested in Salinas, Calif., and in Bogota, Colombia, ultimately resulting in discarding five of these codes, and the decision to introduce one code 0584 as Yellow Tayrona, disclosed in pending application Ser. No. 07/919,257, and one reselected code 0804 as Lemon Tayrona.
The first act of asexual reproduction of Lemon Tayrona was accomplished when vegetative cuttings were taken from the reselection in November 1990 in a controlled environment in Salinas, Calif., by technicians working under supervision of Cornelis P. VandenBerg.
Horticultural examination of controlled flowerings of successive plantings has shown that the unique combination of characteristics as herein disclosed for Lemon Tayrona are firmly fixed and are retained through successive generations of asexual reproduction.
Lemon Tayrona 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., and in Bogota, Colombia, under greenhouse conditions which approximate those generally used in commercial greenhouse practice. The low night temperature tolerance was determined in repeated flowerings in Bogota, Colombia.
The following traits have been repeatedly observed and are determined to be basic characteristics of Lemon Tayrona, which, in combination, distinguish this Chrysanthemum as a new and distinct cultivar:
1. Flat capitulum form.
2. Decorative capitulum type.
3. Light lemon-yellow ray floret color, with a fresh green center of the flower.
4. Diameter across face of capitulum of 63 to 73 mm when fully opened, when grown as a single stem spray cut mum.
5. Photoperiodic flowering response to short days when grown in Salinas, Calif., is 52 to 57 days after start of short days. Flowering response in Bogota, Colombia, under temperatures of minimum 7 degrees Celsius night and maximum 29 degrees Celsius day is 66 to 68 days.
6. Plant height is 74 to 79 cm when grown in Salinas with 7 to 10 long days prior to start or short days; height is 102 to 117 cm when grown in Bogota with 14 long days prior to start of short days.
7. Peduncle length of the first lateral at flowering after removing the apical bud without growth regulator applications is 10 cm when grown in Salinas, and 15 cm when grown in Bogota. Peduncle length of the fourth lateral at flowering is 13 cm when grown in Salinas, and 20 to 23 cm when grown in Bogota.
8. Excellent tolerance to minimum low night temperatures of 7° C. for bud initiation and flower development.
The accompanying photographic drawing is a side view of single stem cut spray mum of Lemon Tayrona, with the colors being as nearly true as possible with illustrations of this type.
Of the commercial cultivars known to the inventor, the most similar in comparison to Lemon Tayrona is the parent cultivar Tayrona. All traits of Lemon Tayrona are similar to those of Tayrona, except for the ray floret color, the flowering response and the plant height. Lemon Tayrona has a light lemon-yellow ray floret color, while Tayrona has a white ray floret color. Both Lemon Tayrona and Tayrona have a fresh green center of the flower. In several of our trials in Salinas Lemon Tayrona has been slightly slower in flowering response by one to two days than Tayrona. In one trial in Salinas Lemon Tayrona was 5 cm taller than Tayrona. In a recent flowering in Bogota, Colombia, Lemon Tayrona was one day slower in flowering response and 8 cm taller when compared with Tayrona.
In the following description color references are made to The Royal Horticultural Society Colour Chart. The color values were determined on plant material grown as a single stem spray cut mum in Salinas, Calif. on Dec. 27, 1991.
