Description
RELATED CULTIVARS

‘CACHI DARK’ is related to CACHI (U.S. Plant patent application Ser. No. 09/276,699). ‘CACHI DARK’ is a color mutant of Cachi.

BACKGROUND OF THE INVENTION

‘CACHI DARK’ is a product of a breeding and selection program which had the objective of finding color mutants of CACHI. The new plant of the present invention comprises a new and distinct cultivar of chrysanthemum plant that is a natural occuring sport of a parent chrysanthemum named CACHI. A comparison with Parent chrysanthemum CACHI is also made in this application. The new cultivar was discovered as a whole plant mutation in April 1998 by Rob Noodelijk in a controlled environment (greenhouse) in Rijsenhout Holland. The first act of asexual reproduction of ‘CACHI DARK’ was accomplished when vegetative cuttings were taken from the initial selection in June 1998 in Rijsenhout Holland.

SUMMARY OF THE INVENTION

The present invention is a new and distinct variety of chry santhemum bearing small sized blooms with yellow ray-florets and disc florets grown to a cushion of yellow color with brown tips.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chry santhemum 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 various stages of foliage and petiole of the new cultivar.

DESCRIPTION OF THE INVENTION

This new variety of chrysanthemum is of the botanical classi fication dendranthema grandiflora. The observations and measurements were gathered from 56 days plants grown in a greenhouse in Rijsenhout Holland 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. The photo-periodic response time in this crop was 48 days after an average of eight long days. After this long day period to flowering growth retardants were applied 6 times in an average dose of 1.5 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 small sized blooms with yellow ray-florets and disc-florets grown to an anemone cushion of yellow color with brown tips, blooming on the plant for 5 weeks. 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 ‘CACHI DARK’ can be planted without assimilation lightning (high pressure sodium lamps) between week 50 and week 40 of the next year uner greenhouse conditions in Holland. With assimilation light (minimum level 2500 lux) it can be planted year round under greenhouse conditions in Holland.

From the cultivars known to inventor the most similar existing cultivar in comparison to ‘CACHI DARK’ is CACHI. When CACHI and ‘CACHI DARK’ are being compared the following differences and similarities are noticed: The differences of CACHI and ‘CACHI DARK’ is-are the larger and darker brown spot on the center of the flower. For which characteristics ‘CACHI DARK’ has been selected out of CACHI. All other characteristics of CACHI and ‘CACHI DARK’ are similar.

The following is a description of the plant and characteristics that distinguish ‘CACHI DARK’ as a new and distinct variety. The color designations are taken from the plant itself. Accor dingly, 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.
