USPP8052P - Chrysanthemum plant--Puma cultivar - Google Patents

Abstract

A new and distinct cultivar of Chrysanthemum plant named Puma is provided. The new cultivar was the result of a controlled breeding program wherein an unnamed plant designated 86.2378 was pollinated by the Whisper cultivar (non-patented in the United States). More specifically, the new cultivar forms attractive relatively small white anemone-centered flowers having white ray florets and a green 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 Puma.

The new cultivar is the product of a planned breeding program which had as its objective the creation of a new Chrysanthemum cultivar which exhibits attractive small white flowers having a green center when immature, exhibits a flower response period of approximately eight weeks, and possesses the ability to produce flowers of commercially acceptable quality throughout the year in a cut mum production program. Such combination of traits is not believed to have been present in the previously available Chrysanthemum cultivars. This objective was satisfactorily fulfilled in the cultivar of the present invention.

The breeding program which resulted in the production of the new cultivar of the present invention was carried out in a controlled environment during 1987 at De Lier, The Netherlands. The female parent (i.e., the seed parent) was an unnamed plant designated 86.2378 and the male parent (i.e., the pollen parent) was the Whisper cultivar (non-patented in the United States). The parentage of the new cultivar can be summarized as follow:

86.2378×Whisper.

The seeds resulting from the above pollination were sown and plantlets were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

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

(a) exhibits attractive relatively small anemone-centered flowers having an overall diameter of approximately 40 to 45 mm. wherein the ray florets are white and the flower center comprising the disc florets is approximately 22 mm. in diameter wherein the disc florets are green in coloration 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 initially taken during January, 1988, 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.

Puma 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 Majoor Bosshardt cultivar (U.S. plant patent application Ser. No. 07/680136, filed concurrently herewith), the following characteristics are observed:

Also at the harvest stage one can observe a disparity in the development of the petaloids at the flower center. More specifically, such petaloid development is considerably greater in Puma than in Majoor Bosshardt.
