Chrysanthemum plant named ‘Omega Time Orange’

Abstract

A new variety of Chrysanthemum plant named ‘Omega Time Orange’, having pastel orange single flowers with a green disc. The new variety has a strong medium to tall vigor 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 ‘Omega Time Orange’.

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 ‘Omega Time Orange’.

‘Omega Time Orange’, identified as 20929-21 was discovered as a naturally occurring whole plant mutation in a controlled cultivated planting of the variety ‘Mega Time Rose’ (U.S. Plant Pat. No. 15,004).

The new variety ‘Omega Time Orange’ 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

‘Omega Time Orange’ is a pot type of Chrysanthemum plant variety having pastel orange single flowers with a green disc.

Comparison With Original Cultivar

Plants of the new Chrysanthemum variety ‘Omega Time Orange’ are similar to the original cultivar ‘Mega Time Rose’ in plant habit and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chyrsanthemum variety ‘Omega Time Orange’ compared to plants of the original cultivar ‘Mega Time Rose’ in the following characteristics:

• • 1. The new variety ‘Omega Time Orange’ produces orange single flowers whereas ‘Mega Time Rose’ produces pink single flowers.
  • 2. Plants of the new variety ‘Omega Time Orange’ have the same sized inflorescence as plants of ‘Mega Time Rose’.

Comparison with ‘Swing Time Dark’

Plants of the new Chrysanthemum variety ‘Omega Time Orange’ are dissimilar to plants of the variety ‘Swing Time Dark’ (U.S. Plant Pat. No. 14,896) 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 ‘Omega Time Orange’ differed from plants of ‘Swing Time Dark’ in the following characteristics:

• • 1. The new variety ‘Omega Time Orange’ produces pastel orange colored single flowers whereas ‘Swing Time Dark’ produces dark orange single flowers.
  • 2. Plants of the new variety ‘Omega Time Orange’ have larger and taller inflorescence than plants of ‘Swing Time Dark’.
  • 3. Plants of the new variety ‘Omega Time Orange’ have a quicker response than plants of ‘Swing Time Dark’.

DETAILED BOTANICAL DESCRIPTION

The following description of the new Chrysanthemum variety ‘Omega Time Orange’ 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 18° C. at night and about 24° C. to 25° C. during the day under light conditions of about 2500 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 7.5 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.).
