Abstract

A Chrysanthemum plant named ‘Ceregina White’ characterized by its large sized spider type blooms with white ray-florets, with a response time of 52 days, and which is grown as a disbud.

Description

BACKGROUND OF THE INVENTION
‘Ceregina White’ is a product of a breeding-program which had the objective of creating new chrysanthemum cultivars with a double type flower, a 7.5 week response and a medium plant height (90 cm). The new plant of the present invention comprises a new and distinct cultivar of Chrysanthemum plant. ‘Ceregina White’ is a seedling from a cross in a breeding program maintained under the control of inventor. The female parent is #92154-unpatented-, an unnamed seedling not available to inventor for description. The male parent is unknown, being a mixed population of a group of male parents. The new and distinct cultivar was discovered and selected as a flowering plant within the progeny of the stated cross by Mark Roland Boeder in a controlled environment (greenhouse) in Rijsenhout, The Netherlands in 2001. The first act of asexual reproduction of ‘Ceregina White’ was accomplished when vegetative cuttings were taken from the initial selection in 2001 and propagated further in a controlled environment in Rijsenhout, The Netherlands.
SUMMARY OF THE INVENTION
The present invention is a new and distinct variety of chrysanthemum bearing large sized double type blooms with white ray-florets, which is grown as a disbud.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention of a new and distinct variety of chrysanthemum is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.
FIG. 1 shows a plant of the cultivar in full bloom.
FIG. 2 shows the various stages of bloom of the new cultivar.
FIG. 3 shows the foliage of the new cultivar.
 DESCRIPTION OF THE INVENTION
This new variety of chrysanthemum is of the botanical classification Chrysanthemum morifolium. The observations and measurements were gathered from plants grown in April/May in a greenhouse in Rijsenhout, The Netherlands in a photo-periodic controlled crop under conditions generally used in commercial practice. The greenhouse temperatures during this crop were at day-time between 18° C. and 25° C. and at night 20° C. After a long day period of 14 days the photo-periodic response time in this crop was 52 days. After the long day period to flowering growth retardants were applied 2 to 3 times in an average dose of 2.5 gram/liter water. The plants were observed (directly) during the flowering of this crop. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought tolerance. This new variety produces large sized blooms with white ray-florets blooming on the plant for 1 week. This new variety of chrysanthemum has been found to retain its distinctive characteristics throughout successive propagations however the phenotype may vary significantly with variations in environment such as light intensity and temperature. To show the phenotype as described ‘Ceregina White’ can be planted without assimilation lightning (high pressure sodium lamps) between week 4 and week 36 under greenhouse conditions in The Netherlands. With assimilation light (minimum level 2500 lux) it can be planted year round under greenhouse conditions in The Netherlands.
From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Ceregina White’ is ‘Resomee White’ (U.S. Plant patent application Ser. No. 11/020,211). When ‘Resomee White’ and ‘Ceregina White’ are being compared the following differences and similarities are noticed: Both ‘Resomee White’ and ‘Ceregina White’ have white double type blooms. The differences of ‘Resomee White’ and ‘Ceregina White’ are (1) Center of the bloom. In the mature stage, the center of the bloom is cream in ‘Resomee White’ and yellow-green in ‘Ceregina White’. (2) Cross section of ray florets. The cross section is flat to concave in ‘Resomee White’ and convex in‘Ceregina White’. (3) Longitudinal axis of majority of ray florets. This axis is straight in ‘Resomee White’ and incurving in ‘Ceregina White’.
The following is a description of the plant and characteristics that distinguish ‘Ceregina White’ as a new and distinct variety. The color designations are taken from the plant itself. Accordingly, any discrepancies between the color designations and the colors depicted in the photographs are due to photographic tolerances. The color chart used in this description is: The Royal Horticultural Society Colour Chart, edition 1995.
