Chrysanthemum plant named ‘Radiant Time’

Abstract

A new variety of Chrysanthemum plant named ‘Radiant Time’, having medium sized yellow and red blooms and a light green disc. The variety has a strong medium vigor with good foliage presentation and a long shelflife.

Description

Latin name of the genus and species: Botanical classification: Chrysanthemum morifolium.

Variety denomination: The new Chrysanthemum variety denomination is ‘Radiant Time’.

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 ‘Radiant Time’.

‘Radiant Time’, identified as 21589-0 originated from a cross made in a controlled breeding program in Chichester, West Sussex, United Kingdom.

The female parent of the new variety is Machismo Time (U.S. Plant Patent Application Publication No. 2003/0056261), identified as 20360-0. The male parent is the variety known as Swing Time Dark, (U.S. Plant Pat. No. 14,896). The new variety ‘Radiant Time’ 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

‘Radiant Time’ is a pot type of Chrysanthemum plant variety having medium sized blooms with yellow and red ray florets and yellow-green disc.

Comparison with Female Parent

Plants of the new Chrysanthemum variety ‘Radiant Time’ are dissimilar to the female parent ‘Machismo Time’ in plant habit and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Radiant Time’ differed from plants of the female parent ‘Machismo Time’ in the following characteristics:

• • 1. The new variety ‘Radiant Time’ produces medium large yellow and red single flowers whereas the female parent ‘Machismo Time’ produces medium small yellow and red single flowers.
  • 2. Plants of the new variety ‘Radiant Time’ have larger and taller inflorescence than plants of the female parent ‘Machismo Time’.
  • 3. Plants of the new variety ‘Radiant Time’ have a quicker response time than the plants of ‘Machismo Time’.
  • 4. Plants of the new variety ‘Radiant Time’ have a medium vigor whereas plants of ‘Machismo Time’ have a taller vigor.

Comparison with Male Parent

Plants of the new Chrysanthemum variety ‘Radiant Time’ are dissimilar to the male parent ‘Swing Time Dark’ in plant habit and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Radiant Time’ differed from plants of the male parent ‘Swing Time Dark’ in the following characteristics:

• • 1. The new variety ‘Radiant Time’ produces yellow and red single flowers whereas the male parent ‘Swing Time Dark’ produces orange single flowers.
  • 2. Plants of the new variety ‘Radiant Time’ have larger and taller inflorescence than plants of the male parent ‘Swing Time Dark’.

Comparison with ‘Doing Time’

Plants of the new Chrysanthemum variety ‘Radiant Time’ are similar to plants of the unpatented variety ‘Doing Time’ 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 ‘Radiant Time’ compared to plants of ‘Doing Time’ in the following characteristics:

• • 1. The new variety ‘Radiant Time’ produces flatter form of yellow and red single flowers whereas ‘Doing Time’ produces cupped yellow and red single flowers.
  • 2. Plants of the new variety ‘Radiant Time’ have larger and taller inflorescence than plants of ‘Doing Time’.
  • 3. Plants of the new variety ‘Radiant Time’ have a longer shelflife than plants of ‘Doing Time’.

DETAILED BOTANICAL DESCRIPTION

The following description of the new Chrysanthemum variety ‘Radiant Time’ is of plants grown in a greenhouse in Chichester, West Sussex, United Kingdom, in the month of October. 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 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 about 2,500 Lux. The plants respond well to the use of growth retardant, such as one B9 treatment at about 2 grams 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 28 days with a response time of about 7 weeks. The new variety is suitable for growth in a temperature range of 15° C. to 25° C.

The following description is with respect to a plant produced as pot Chrysanthemum. 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.).
