ORIGIN AND HISTORY OF THE NEW PLANT

The new plant of the present invention comprises a new and distinct cultivar of Chrysanthemum plant which is an induced mutation by gamma irradiation of a chrysanthemum named Reagan, which in turn is a cross of unknown Chrysanthemum morifolium parents. The chrysanthemum named Reagan is described in U.S. patent application Ser. No. 07/780,305. The invention was discovered by Martinus van der Jagt, Langeraarseweg 161F, 2461 CJ Langeraar, Holland in 1988. The invention has been asexually reproduced by cuttings in greenhouses at Ter Aar, Holland. The new cultivar has been found to retain its distinctive characteristics through successive propagations.

SUMMARY OF THE NEW PLANT

The present invention is a new and distinct variety of chrysanthemum of a medium sized bloom and orange color.

BRIEF DESCRIPTION OF THE DRAWINGS

The present new and distinct Chrysanthemum cultivar is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.

Sheet 1 shows the full bloom of the new cultivar;

Sheet 2, top, shows various stages of bloom of the new cultivar; and

Sheet 2, bottom, shows the foliage and petiole of the new cultivar.

DESCRIPTION OF THE INVENTION

This new variety of Chrysanthemum is of the botanical classification Chrysanthemum morifolium, and is named Orange Reagan. When grown in the vicinity of Ter Aar, Holland, it has a response time of approximately 71/2 weeks. This new variety produces medium sized orange blooms with a yellow green center having a 4 week performance (i.e., a Vase life of 24-28 days). This new variety of Chrysanthemum has been found to retain its distinctive characteristics throughout successive propagations and may be planted under greenhouse conditions in Holland between weeks fifty and thirty-five (i.e., between December 1 and August 30). Pest resistance, disease resistance and frost tolerance are unknown.

Three groups consisting of 300, 300 and 400 cuttings, respectively, of the parent Reagan chrysanthemum were irradiated at 1250, 1500 and 1750 RAD, respectively. The cultivar of the present application was taken from the second group.
