Abstract

A new and distinct Chrysanthemum cultivar named `Chahalu` is provided. The new cultivar is a mutation of the `Chalecat` cultivar (U.S. Plant patent application Ser. No. 08/273,998, filed Jul. 12, 1994). Attractive very large double incurved blossoms of the pompon type are formed that are lemon yellow. The blossoms are long lasting and keep their form for approximately three weeks. The response period of the flowers is approximately nine weeks. Recurrent profuse flower production throughout the year is possible. The plant possesses strong stems, forms dark green glossy leaves, and commonly assumes a height of approximately 45 to 50 cm. The light blossom coloration contrasts nicely with the dark green foliage. The new cultivar is particularly suited for use in the production of a decorative pot Chrysanthemum that grows well single stem or disbudded. No growth regulator is necessary to achieve the short to medium plant height.

Description

SUMMARY OF THE INVENTION
The present invention comprises a new and distinct cultivar of Chrysanthemum, botanically known as Dendranthema grandiflora, and hereinafter is referred to by the cultivar name `Chahalu`.
The new cultivar of the present invention was created through the gamma irradiation of the `Chalecat` cultivar U.S. Plant patent application Ser. No. 08/273,998, filed Jul. 12, 1994). The parent `Chalecat` cultivar was formed by the crossing of the `Siky` cultivar (non-patented in the United States) and the `Prouesse` cultivar (non-patented in the United States) as described in my copending U.S. Plant patent application.
During June 1980, at Saint Paul Lez Durance, France, groups of 1,000 rooted cuttings of the `Chalecat` cultivar having an age of two weeks were irradiated with gamma rays through the packing boxes at rates of 1.8, 2.5 and 3.0 Krads. Following irradiation the plants were shipped to Nuaille, Trementines, France, and planted in 4 liter pots, pinched, and grown outside until September, next grown in greenhouses, were not disbudded, and were carefully observed. It was found that most of the plants irradiated at a rate of 3.0 Krads died. Those plants that were irradiated at a rate of 2.5 Krads exhibits no growth following pinching and were discarded. Many different mutations were observed in the plants that were irradiated at a rate of 1.8 Krads. A single mutation that exhibits the characteristics of the `Chahalu` cultivar were discovered among these plants. Also, a single mutation that exhibits the characteristics of the `Chatupa` cultivar (U.S. Plant patent application Ser. No. 08/273,997, filed Jul. 12, 1994) and a single mutation of the `Chalurido` cultivar (U.S. Plant patent application Ser. No. 08/273,999, filed Jul. 12, 1994) were discovered among the same group of plants. It would have been impossible for a plant scientist to have predicted in advance that new cultivars having the combination of characteristics of the presently claimed `Chahalu` cultivar and the sister `Chatupa` and `Chalurido` cultivars could have been formed even if the parent `Chalecat` cultivar would have been available for such experimentation.
It was found that the new cultivar of the present invention:
(a) exhibits attractive large double incurved pompon blossoms that are lemon yellow in coloration,
(b) exhibits a flower response period of approximately nine weeks,
(c) forms attractive dark green glossy foliage,
(d) achieves a short to medium plant height, and
(e) is particularly suited for pot mum production on a recurrent basis throughout the year.
The new cultivar is intended primarily as a decorative pot Chrysanthemum for growing indoors. However, it also can be grown for cut flower production in those instances where stems of approximately 40 cm. are acceptable. Also the new cultivar can be grown outdoors at temperatures above freezing.
The new cultivar can be grown single-stem or disbudded. An increased number of branches readily can be induced by pinching. The pinching of a cutting commonly produces approximately 4 stems per cutting. No growth regulator is required to produce the short to medium plant height; however, a growth regulator optionally can be utilized.
The new cultivar can be considered to be an October-flowering greenhouse variety with the natural flowering season commonly occurring in weeks 42 and 43 of the year. Attractive blossoms can be produced on a recurrent basis throughout the year with the indicated nine week response period. The blossoms are long lasting and commonly can be maintained on the plant for approximately three weeks, and commonly exhibit a vase life of approximately four weeks.
Asexual reproduction of the new cultivar by cuttings initially taken during 1982, as performed in Nuaille, Trementines, France, in a controlled environment has demonstrated that the characteristics of the new cultivar as herein described are firmly fixed and are retained through successive generations of asexual propagation.
`Chahalu` has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light, day length, contact with pesticides and/or subjection to growth retardant treatments.
The `Chahalu` cultivar of present invention exhibits a combination of characteristics that readily distinguish it from the parent `Chalecat` cultivar. For instance, the `Chahalu` cultivar exhibits a lemon yellow capitulum unlike the `Chalecat` cultivar, a foliage coloration between Green Group 137A and 139A unlike the Yellow-Green Group 147A coloration of the `Chalecat` cultivar, an angular stem cross section unlike the round cross section of the `Chalecat` cultivar, a stem coloration of Yellow-Green Group 144A unlike the Yellow-Green Group 146B of the `Chalecat` cultivar, a coarse leaf serration unlike the medium to fine serration of the `Chalecat` cultivar, a diverging margin of sinus between lateral leaf lobes generally unlike the `Chalecat` cultivar, and a claw at the base of the sinus between lateral leaf lobes unlike the `Chalecat` cultivar.
As indicated, other mutations of the `Chalecat` cultivar are the `Chatupa` cultivar and the `Chalurido` cultivar. Each of these additional cultivars can be readily distinguished from the parent `Chalecat` cultivar with respect to a number of plant characteristics.
The `Chatupa` cultivar exhibits a honey gold capitulum unlike the `Chahalu` cultivar, commonly forms a generally larger capitulum than the `Chahalu` cultivar, a foliage coloration of Green Group 137A unlike the coloration between Green Group 137A and 139A of the `Chahalu` cultivar, a stem coloration between Yellow-Green Group 144A and 144B unlike the Yellow-Green Group 144A coloration of the `Chahalu` cultivar, medium leaf serration unlike the coarse leaf serration of the `Chahalu` cultivar, a leaf base shape of rounded tending to cordate unlike the acute base of the `Chahalu` cultivar, and a converging margin of sinus between lateral leaf lobes unlike the diverging margin of the `Chahalu` cultivar.
The `Chalurido` cultivar exhibits a capitulum having inner surfaces of Venetian violet and silvery lavender outer surfaces unlike the `Chahalu` cultivar, commonly forms a fully opened capitulum having a generally smaller diameter than the `Chahalu` cultivar, a foliage coloration of Yellow-Green Group 147A unlike the coloration between Green Group 137A and 139A for the `Chahalu` cultivar, a more variable fine to coarse leaf serration than the `Chahalu` cultivar, approximately 37 to 40 leaves per typical stem in a long day crop before the bud opens unlike the lesser number of approximately 27 to 31 for the `Chahalu` cultivar, a variable converging margin of sinus between lateral lobes unlike the diverging margin of the `Chahalu` cultivar, and a generally asymmetric leaf base unlike the acute leaf base of the `Chahalu` cultivar.
The new `Chahalu` cultivar is being marketed under the Lemon Cymbal trademark.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs were prepared during June, 1994, and show as nearly true as it is reasonably possible to make the same in color illustrations of this character, typical plants and plant parts of the new cultivar of the present invention. The plants were 12 weeks of age and were grown at Nuaille, Trementines, France, under standard greenhouse conditions which approximate those commonly utilized for the production of decorative pot mums. The plant had been disbudded in order to encourage the formation of one large bloom per stem. There had been one application of Alar growth regulant at a concentration of 3 grams per liter. A measuring tape is included in FIGS. 3 and 4 wherein centimeters and inches are shown for size comparisons.
FIG. 1 illustrates typical specimens of the overall plant wherein five cuttings were placed in a 20 cm. pot. The large incurved lemon yellow blossoms generally in the form of large round balls, as well as the foliage, are apparent.
FIG. 2 illustrates a closer view of a typical flower.
FIG. 3 illustrates from left to right, under, and upper views of largely unopened buds, and buds in the course of opening. The pink coloration that sometimes appears at the bases of the outer sides of the petals, particularly during the natural flowering season, is not apparent.
FIG. 4 illustrates at the top row, the upper surfaces of typical leaves of various sizes, and at the bottom row the under surfaces of typical leaves of various sizes.
DETAILED DESCRIPTION
The chart used in the identification of colors described hereafter is the R.H.S. Colour Chart of the Royal Horticultural Society, London, England. In some instances more common color terms are provided and are to be accorded their usual dictionary significance.
