Abstract

A new variety of Chrysanthemum plant named ‘Grace Time Pearl Improved,’ having a good uniform canopy of light pink quill single flowers with a light green disc. The new variety has a medium vigor and a uniform spreading habit with a good foliage presentation.

Description

Latin name of the genus and species: Botanical classification: Chrysanthemum morifolium.
Variety denomination: The new Chrysanthemum variety denomination is ‘Grace Time Pearl Improved.’
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Chrysanthemum botanically known as Chrysanthemum morifolium, and referred to by the variety name ‘Grace Time Pearl Improved.’ ‘Grace Time Pearl Improved,’ identified as 20911-26, was discovered as a whole plant mutation found in a controlled cultivated planting of the variety ‘Grace Time Pink’ (U.S. Plant patent application Ser. No. 60/524,339). The new variety ‘Grace Time Pearl Improved’ has been asexually reproduced by vegetative cuttings in Chichester, West Sussex, United Kingdom and the distinguishing characteristics are retained through successive generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
‘Grace Time Pearl Improved’ is a pot type of Chrysanthemum plant variety having light pink quill single flowers with a light green disc.
Comparison with Parent
Plants of the new chrysanthemum variety ‘Grace Time Pearl Improved’ are similar to the parent variety ‘Grace Time Pink’ in plant habitat and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new chrysanthemum variety ‘Grace Time Pearl Improved’ compared to plants of the parent ‘Grace Time Pink’ in the following characteristics.
    • 1. The new variety ‘Grace Time Pearl Improved’ produces light pink single quill flowers whereas the parent ‘Grace Time Pink’ produces purple single quill flowers.
    • 2. Plants of the new variety ‘Grace Time Pearl Improved’ have similar inflorescence to the plants of the parent ‘Grace Time Pink.’
Comparison with Other Varieties
Plants of the new Chrysanthemum variety ‘Grace Time Pearl Improved’ are dissimilar to the variety ‘Mogul Time’ (U.S. Plant Pat. No. 14,262) in plant habitat and growth rate. However, in side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Grace Time Pearl Improved’ differed from plants of ‘Mogul Time’ in the following characteristics.
    • 1. The new variety ‘Grace Time Pearl Improved’ produces light pink quill single flowers whereas ‘Mogul Time’ produces purple quill spoon tip single flowers.
    • 2. Plants of the new variety ‘Grace Time Pearl Improved’ have smaller and shorter inflorescence than plants of ‘Mogul Time.’
BRIEF DESCRIPTION OF ILLUSTRATION
Typical specimens of the plant and flowers for the new Chrysanthemum variety ‘Grace Time Pearl Improved’ are shown in the accompanying digital photograph. The colors shown are as true as possible within the usual limits of this kind of illustration.
FIG. 1 is a whole plant view of the new variety ‘Grace Time Pearl Improved’ grown in a pot.
The plant shown in the illustration is 54 days from the commencement of Short Days.
 DETAILED BOTANICAL DESCRIPTION
The following description of the new Chrysanthemum variety ‘Grace Time Pearl Improved’ is of plants grown in a greenhouse in Chichester, West Sussex, United Kingdom in the month of September. The variety has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in the environment such as temperature, length of day and light intensity, without any variance in genotype. The commercial classification of the new variety is a pot Chrysanthemum.
Plants of the new variety have been grown successfully under temperature conditions averaging about 19° C. at night and about 17° C. to 24° C. during the day under light conditions of 5,000 to 6,000 foot candles. The plants respond well to the use of growth retardant, such as one B9 treatment at about 2 gm per liter. To produce a commercial product the plants may be pinched once with the center bud removed. The typical container size for commercial growth is 1 liter. It has been observed that the shelf life of the new variety is about 21 days with a response time of about 7.5 weeks. The new variety is suitable for growth in a temperature range of 15° C. to 25° C.
The new variety may be produced as a spray. The following description is with respect to a plant produced as pot. In the description of this new Chrysanthemum variety, color values have been taken from The Royal Horticultural Society Colour Chart (R.H.S.C.C.).
