Abstract

A new variety of Chrysanthemum plant named ‘Starlet White,’ having a good uniform canopy of small white single flowers. The new variety has medium vigor, a free branching and uniform spreading habit, and good foliage presentation.

Description

Latin name of the genus and species: Botanical classification: Chrysanthemum morifolium.
Variety denomination: The new Chrysanthemum variety denomination is ‘Starlet White.’
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 cultivar name ‘Starlet White.’
‘Starlet White,’ identified as 30450-0, originated from a cross made in a controlled breeding program in Chichester, West Sussex, United Kingdom. The female parent of the new variety is the unpatented variety known as ‘Leyla.’ The male parent of the new variety is the variety known as ‘Pidoul’ (U.S. Plant Pat. No. 10,218).
The new variety ‘Starlet White’ 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
‘Starlet White’ is a garden type of Chrysanthemum plant variety having a uniform domed and round shape carrying many small white single flowers.
Comparison With Female Parent
Plants of the new Chrysanthemum variety ‘Starlet White’ are similar to the female parent variety ‘Leyla’ 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 ‘Starlet White’ differed from plants of the parent ‘Leyla’ in the following characteristics.
    • 1. The new variety ‘Starlet White’ produces white flowers whereas the parent ‘Leyla’ produces yellow flowers.
    • 2. Plants of the new variety ‘Starlet White’ have smaller and shorter inflorescence than plants of the parent ‘Leyla.’
Comparison With Male Parent
Plants of the new Chrysanthemum variety ‘Starlet White’ are similar to the male parent ‘Pidoul’ in plant habit and growth rate. However, in side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Starlet White’ differed from plants of the parent ‘Pidoul’ in the following characteristics.
    • 1. The new variety ‘Starlet White’ has smaller white single flowers than the parent variety ‘Pidoul.’
    • 2. Plants of the new variety ‘Starlet White’ have less flowers than the parent variety ‘Pidoul.’
    • 3. Plants of the new variety ‘Starlet White’ are less vigorous than plants of the parent variety ‘Pidoul.’
Comparison With Other Varieties
Plants of the new Chrysanthemum variety ‘Starlet White’ are similar to the unpatented variety ‘Tightrope’ in plant habit and growth rate. However, in side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Starlet White’ differed from plants of ‘Tightrope’ in the following characteristics.
    • 1. The new variety ‘Starlet White’ has smaller white single flowers than the variety ‘Tightrope.’
    • 2. Plants of the new variety ‘Starlet White’ have more flowers than the variety ‘Tightrope.’
    • 3. Plants of the new variety ‘Starlet White’ are less vigorous than plants of the variety ‘Tightrope.’
BRIEF DESCRIPTION OF ILLUSTRATION
Typical specimens of the plant and flowers for the new Chrysanthemum variety ‘Starlet White’ 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 ‘Starlet White’ grown in a pot.
The plant shown in the illustration is 63 days from the commencement of planting outdoors in mid-June.
 DETAILED BOTANICAL DESCRIPTION
The following description of the new Chrysanthemum variety ‘Starlet White’ is of plants grown outside, natural season, in Chichester, West Sussex, United Kingdom in the month of June. The cultivar 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 garden Chrysanthemum.
Plants of the new variety have been grown successfully under temperature conditions averaging about 50° F. at night and about 65° F. to 75° F. during the day under natural light conditions. The plants were grown outdoors in mid-June in 4 liter pots using loamless compost. No growth retardants were used. To produce a commercial product the plants may be pinched once with the center bud removed. The typical container size for commercial growth is 4 liter. It has been observed that the shelf life of the new variety is about 25 days with a response time of about 9 weeks natural season. The new variety is suitable for growth in a temperature range of 50° F. to 75° F.
The new variety may be produced as a pot plant. The following description is with respect to a plant produced as garden pot plant. 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.).
