Abstract

A Chrysanthemum plant named Yellow Davis particularly characterized by its flat capitulum form; daisy capitulum type; yellow ray floret color; diameter across face of capitulum of 64 to 70 mm when fully opened, when grown as a pinched spray pot mum; photoperiodic flowering response to short days of 56 to 61 days; plant height, with 15 to 16 long days after sticking unrooted cuttings and with 1 to 2 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; branching pattern is spreading, each plant having 4 to 6 laterals after pinch; and recommended as spray pot mum.

Description

The present invention comprises a new and distinct cultivar of Chrysanthemum, botanically known as Dendranthema grandiflora, and referred to by the cultivar name Yellow Davis.
Yellow Davis, identified as 5439 (84-382J03), is a product of a mutation induction program. The new cultivar was discovered and selected by Susan M. Polys on Apr. 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 Nov. 21, 1991. The irradiated parent cultivar was the cultivar identified as Light Davis, disclosed in U.S. Plant Pat. No. 8,293.
The irradiation program resulting in Yellow Davis had as its primary objective the expansion of color ranges of the parent cultivar Light Davis. The irradiation program comprised irradiating cuttings of the parent cultivar at irradiation levels of 1500 and 1750 rads. A total of 541 cuttings harvested from a total of 150 irradiated plants were planted on Feb. 24 and Feb. 10, 1992. Of these, 4 initial selections were made, which selections were then revegetated and reflowered. Three consecutive flowerings resulted in discarding 3 of the original 4 selections on Dec. 21, 1992. Continued flowering trials resulted in the decision to introduce the one remaining selection as Yellow Davis.
The first act of asexual reproduction of Yellow Davis was accomplished when vegetative cuttings were taken from the initial selection in June 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 Yellow Davis are firmly fixed and are retained through successive generations of asexual reproduction.
Yellow Davis 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 Yellow Davis, which, in combination, distinguish this Chrysanthemum as a new and distinct cultivar.
1. Flat capitulum form.
2. Daisy capitulum type.
3. Yellow ray floret color.
4. Diameter across face of capitulum of 64 to 70 mm when fully opened, when grown as a pinched spray pot mum.
5. Photoperiodic flowering response to short days of 56 to 61 days.
6. Plant height, with 15 to 16 long days after sticking unrooted cuttings and with 1 to 2 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.
7. Branching pattern is spreading, each plant having 4 to 6 laterals after pinch.
8. Recommended as spray pot mum.
The accompanying photographic drawing is a side view of a potted mum of Yellow Davis, with 4 cuttings in a 15 cm pot, 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 Yellow Davis is the parent cultivar Light Davis. All traits of Yellow Davis are similar to those of Light Davis except for ray floret color. The ray floret color of Yellow Davis is yellow, compared with the light red-purple ray floret color of Light Davis.
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 pinched spray pot mum in Salinas, Calif. on Jun. 22, 1993.
