USPP8041P - Chrysanthemum plant--Bronze Mundial cultivar - Google Patents

Abstract

A new and distinct cultivar of Chrysanthemum plant named Bronze Mundial is provided. The new cultivar is a spontaneous mutation of the Mundial cultivar (U.S. Plant patent application Ser. No. 679,528, filed concurrently herewith). More specifically, the new cultivar forms attractive relatively large yellow-orange anemone-centered flowers having a hint of green at the center when immature. The inflorescence tends to be pyramidal in configuration. The response period of the flowers is approximately eight weeks. The new cultivar is particularly suited for use in the production of a cut anemone spray under greenhouse conditions.

Description

SUMMARY OF THE INVENTION

The present invention comprises a new and distinct cultivar of Chrysanthemum, botanically known as Dendranthema morifolium Ramat., previously, Chrysanthemum morifolium, Ramat., and hereinafter is referred to by the cultivar name Bronze Mundial.

The new cultivar is a spontaneous mutation of unknown causation which was discovered during December, 1987 during the course of plant selection work which was conducted by me. The new cultivar was discovered among plants of the Mundial cultivar (U.S. plant patent application Ser. No. 679,528, filed concurrently herewith) being grown under my direct supervision at De Lier, The Netherlands, which formed blossoms having ray florets possessing the characteristic light red-purple coloration.

It was observed that a single plant consistently formed flowers having ray florets of a distinctive yellow-orange coloration. All of the other characteristics of this plant were found to be substantially identical to those of the Mundial cultivar. Had I not discovered, carefully studied, and preserved this new cultivar it would have been lost to mankind. This new cultivar is particularly well suited for growing in the production of a cut anemone spray.

It was found that the new cultivar of the present invention:

(a) exhibits attractive relatively large anemone-centered flowers having an overall diameter of approximately 75 to 80 mm. wherein the ray florets are yellow-orange and the disc florets have a hint of green at the center when immature,

(b) bears flowers in a somewhat pyramidal configuration,

(c) exhibits a flower response period of approximately eight weeks, and

(d) has the ability to produce flowers of commercially acceptable quality throughout the year in a cut mum production program.

Asexual reproduction of the new cultivar by cuttings as performed at De Lier, The Netherlands, in a controlled environment has demonstrated that the characteristics of the new cultivar as herein disclosed are firmly fixed and are retained through successive generations of asexual propagation.

Bronze Mundial has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light, day length, contact with pesticides and/or subjection to growth retardant treatments.

When the new cultivar of the present invention is compared to the parent Mundial cultivar (U.S. plant patent application Ser. No. 679,528, filed concurrently herewith), it is found to exhibit a distinctive yellow-orange floret coloration unlike the light red-purple floret coloration of its parent. Also, such floret coloration can be readily distinguished from purple floret coloration of the additional mutation of the Mundial cultivar named Royal Mundial (U.S. plant patent application Ser. No. 679,514, filed concurrently herewith).

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same in a color illustration of this character, a typical specimen of an overall plant of the new cultivar. The plant was grown in a greenhouse at De Lier, The Netherlands.

DETAILED DESCRIPTION

The chart used in the identification of colors described hereafter is the R.H.S. Colour Chart of the Royal Horticultural Society, London, England. The color values were determined at 11:00 a.m. to 12:00 noon under natural daylight conditions at De Lier, The Netherlands, during November, 1989. The plants described were grown under standard greenhouse conditions which approximate those commonly utilized for the production of cut mums.
