| Abstract: |
A daisy capitulum type of chrysanthemum plant which is a sport of the cultivar Circus, disclosed in U.S. Plant Pat. No. 4,188. Cirbronze is distinguished from the parent cultivar by its medium bronze ray floret color. |
| Claim: |
We claim:
1. A new and distinct cultivar of Chrysanthemum morifolium, Ramat., known by the cultivar name Cirbronze and particularly characterized as to uniqueness by the combined characteristicsof daisy capitulum type; flat capitulum form; medium bronze ray floret color, diameter across face of capitulum from 55 to 75 mm. at maturity; uniform nine week flowering response to photoperiodic control; medium plant height; and semi-spreadingbranching pattern. |
| Description: |
The present invention comprises a new and distinct cultivar of Chrysanthemum morifolium, Ramat., hereinafter referred to by the cultivar name of Cirbronze.
Cirbronze is a product of planned sport induction program which had the objective of expanding the color range of the parental cultivar, Circus (U.S. Plant Pat. No. 4,188).
Cirbronze was discovered and selected by William E. Duffett and Jack M. Meek on Feb. 14, 1977 as one plant within a flowering block of Circus in a controlled environment in Barberton, Ohio. Plants within the flowering block were derived fromstock plants which had been irradiated as rooted cuttings with an x-ray source of 2600 r units.
The first act of asexual reproduction of Cirbronze was accomplished when vegetative cuttings were taken from the initial selection in April, 1977 in a controlled environment in Barberton, Ohio by a technician working under formulationsestablished and supervised by William E. Duffett and Jack M. Meek. Horticultural examination of selected units initiated Apr. 25, 1978 has demonstrated that the combination of characteristics as herein disclosed for Cirbronze are firmly fixed and areretained through successive generations of asexual reproduction.
Cirbronze 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. The following observations, measurements, andcomparisons describe plants grown in Salinas, Calif. under greenhouse environmental conditions which approximate those generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Cirbronze which in combination distinguish this chrysanthemum as a new and distinct cultivar:
(1 ) Daisy capitulum type.
(2) Flat capitulum form.
(3) Medium bronze ray floret color.
(4 ) Diameter across face of inflorescence ranging from 55 to 75 mm. at maturity.
(5) Uniform nine week photoperiodic flowering response to short days.
(6) Medium plant height (requires 1 to 2 long day weeks prior to short days and one application 2500 ppm B-9 SP 14 to 21 days after the beginning of short days to attain a flowered plant height of 30 to 45 cm. when grown as a pinched pot foryear round flowerings).
(7) Semi-spreading branching pattern.
(8) Yellow green (immature) to yellow (mature) disc floret color.
The accompanying color photographic drawing shows typical inflorescence and foliage characteristics of Cirbronze. Some difficulty was encountered in obtaining accurate color representation, the photographic rendition being more blue and less redthan the actual flower color of Cirbronze. The color readings in the following description are, however, correct.
Of the many commercial cultivars known to the present inventors, the most similar existing cultivars in comparison to Cirbronze are the parental cultivar Circus and Dixie (U.S. Plant Pat. No. 3,655). Reference is made to attached Chart A whichcompares certain characteristics of Cirbronze with the same characteristics of Circus and Dixie. General comparisons are as follows:
(1.) In comparison to Circus, Cirbronze has different ray floret color, with all other characteristics being similar to those same characteristics of Circus.
(2) In comparison to Dixie, Cirbronze has less orange ray floret color, smaller diameter across face of capitulum, and taller plant height. The branching pattern, flowering response period, capitulum form, and capitulum type of Cirbronze aresimilar to those same characteristics of Dixie.
In the following description, color references are made to The Royal Horticultural Society Colour Chart. The color values for the foliage and reproductive organs were determined between 11:00 and 11:30 A.M. on June 8, 1978 under 200 foot-candlelight intensity at Salinas, Calif. The color values for the inflorescence were determined between 10:30 and 11:00 A.M. on Jan. 29, 1979 under 100 foot-candle light intensity at Salinas, Calif.
