Abstract: A new variety of Chrysanthemum plant named `Mega Time Yellow,` having medium size, yellow single flowers with a small dark brown spot in the center of a lime green disc. The new variety has a medium vigor with a free branching uniform habit and a good foliage presentation.
Claim: What is claimed is:

1. A new and distinct variety of Chrysanthemum plant, substantially as described and illustrated herein.
Description: Latinname of the genus and species: Botanical classification: Chrysanthemum morifolium.

Variety denomination: The new Chrysanthemum variety denomination is `Mega Time Yellow`.

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 `Mega Time Yellow`.

`Mega Time Yellow`, identified as 20929-11 was discovered as a naturally occurring whole plant mutation in a controlled cultivated planting of the variety `Mega Time Amber` (U.S. Plant Pat. No. 15,194).

The new variety `Mega Time Yellow` 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

`Mega Time Yellow` is a pot type of Chrysanthemum plant variety having bright yellow single flowers with a small brown spot in the middle of a lime green disc.

Comparison with Parent

Plants of the new Chrysanthemum variety `Mega Time Yellow` are similar to the parent `Mega Time Amber` in plant habit and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants ofthe new Chrysanthemum variety `Mega Time Yellow` differed from plants of the parent `Mega Time Amber` in the following characteristics: 1. The new variety `Mega Time Yellow` produces bright yellow single flowers whereas the parent `Mega Time Amber`produces amber/golden single flowers. 2. Plants of the new variety `Mega Time Yellow` have a slower response than plants of the parent `Mega Time Amber`.

Comparison with Swing Time Yellow

Plants of the new Chrysanthemum variety `Mega Time Yellow` are dissimilar to plants of the variety `Swing Time Yellow` (U.S. Plant Pat. No. 15,463) in plant habit and growth rate. However, in side-by-side comparisons in Chichester, WestSussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety `Mega Time Yellow` differed from plants of `Swing Time Yellow` in the following characteristics: 1. The new variety `Mega Time Yellow` produces bright yellowsingle flowers with a small brown spot in the center of the disc whereas `Swing Time Yellow` produces golden yellow single flowers with a light green disc. 2. Plants of the new variety `Mega Time Yellow` have smaller and shorter inflorescence thanplants of `Swing Time Yellow`. 3. Plants of the new variety `Mega Time Yellow` have lighter foliage than plants of `Swing Time Yellow`. 4. Plants of the new variety `Mega Time Yellow` have a slower response time than plants of `Swing Time Yellow`.

BRIEF DESCRIPTION OF ILLUSTRATIONS

Typical specimens of the plant and flowers for the new Chrysanthemum variety `Mega Time Yellow` 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 `Mega Time Yellow` grown in a pot. The plant shown in the illustration is 60 days from the onset of Short Days.

DETAILED BOTANICAL DESCRIPTION

The following description of the new Chrysanthemum variety `Mega Time Yellow` is of plants grown in a greenhouse in Chichester, West Sussex, United Kingdom, in the month of June. The cultivar has not been observed under all possibleenvironmental 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 potChrysanthemum.

Plants of the new variety have been grown successfully under temperature conditions averaging about 19.degree. C. at night and about 17.degree. C. to 24.degree. C. during the day under light conditions of about 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 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 is1 liter. It has been observed that the shelf life of the new variety is about 28 days with a response time of about 8.5 weeks. The new variety is suitable for growth in a temperature range of about 15.degree. C. to 25.degree. 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.).
