Description
BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Dendranthema grandiflora and referred to by the cultivar name Sparkling Yolaurie.

The new cultivar is a product of a mutation induction breeding program conducted by the inventor in Fort Myers, Fla., and Salinas, Calif. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having with desirable inflorescence form and color and good garden performance.

The new cultivar originated by exposing unrooted cuttings of the Chrysanthemum cultivar Laurie (discloed in U.S. Plant Pat. No. 9,818) to X-ray radiation at a level of 1,750 rads in December, 1994. Following the radiation treatment, the cuttings were rooted and terminal apices were removed (pinched) three times to promote lateral branch development. After lateral branches from the third pinch reached sufficient size, terminal cuttings were harvested, planted and flowered in a controlled environment in Salinas, Calif. The cultivar Sparkling Yolaurie was discovered and selected by the inventor as a single flowering plant within this population in June, 1995. The selection of this plant was based on its desirable ray floret color.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Salinas, Calif., has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Sparkling Yolaurie has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sparkling Yolaurie’. These characteristics in combination distinguish ‘Sparkling Yolaurie’ as a new and distinct cultivar:

1. Uniformly mounded plant habit.

2. Decorative-type inflorescences that are about 4.2 cm in diameter.

3. Attractive bright yellow-colored ray florets.

4. Numerous inflorescences per plant.

Plants of the new Chrysanthemum can be compared to plants of the parent cultivar Laurie. However, in side-by-side comparisons conducted by the Inventor under commercial practice, plants of the new Chrysanthemum differed from plants of the cultivar Laurie in the following characteristics:

1. Plants of the new Chrysanthemum are taller than plants of the cultivar Laurie.

2. Plants of the new Chrysanthemum have larger inflorescence discs than plants of the cultivar Laurie.

3. Plants of the new Chrysanthemum flower later than plants of the cultivar Laurie.

4. Ray floret color of plants of the new Chrysanthemum is bright yellow whereas ray floret color of plants of the cultivar Laurie are orange bronze.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new cultivar.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sparkling Yolaurie’.

The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences of the cultivar ‘Sparkling Yolaurie’. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Floret and foliage colors in the photographs may differ from the actual colors due to light reflectance.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Leamington, Ontario, Canada, under conditions which approximate those generally used in commercial garden Chrysanthemum production. One rooted cutting was planted in a 15-cm container on Jul. 20, 1998 and plants were grown outdoors under natural season conditions. Measurements and numerical values represent averages for typical flowering containers.

Botanical classification: Dendranthema grandiflora cultivar Sparkling Yolaurie.
