Latest Chrysanthemum Breeders Association N.V. Patents:
The new plant of the present invention comprises a new and distinct cultivar of chrysanthemum plant that is a cross of unknown Dendranthema grandiflora parents. The new and distinct cultivar was a seedling resulting from the open pollination among groups of chrysanthemum cultivars maintained under the control of the inventor for breeding purposes. The new and distinct cultivar was discovered and selected as one flowering plant by Rob Noodelijk on a cultivated field in Rijsenhout, Holland in August, 1996. The plant has been asexually reproduced by cuttings in greenhouses at Rijsenhout, Holland. The new cultivar has been found to retain its distinctive characteristics through successive propagations.
SUMMARY OF THE INVENTIONThe present invention is a new and distinct variety of chrysanthemum of a medium sized bloom and yellow color.
BRIEF DESCRIPTION OF THE DRAWINGSThe 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 various stages of bloom.
FIG. 2 shows the various stages of bloom of the new cultivar.
FIG. 3 shows foliage of the new cultivar.
DESCRIPTION OF THE INVENTIONThis new variety of chrysanthemum is of the botanical classification Dendranthema grandiflora. The observations and measurements were gathered from plants grown outdoors in Rijsenhout, Holland under natural day length and temperature and planted week 22 in 1997 and 1998. The natural blooming date for this crop was August 1-4 (week 31). The average height of the plants was 20 cms. This new variety produces medium sized blooms with yellow ray and disc florets blooming for a period of 5 weeks.
The following is a description of the plant and characteristics that distinguish Xanthus as a new and distinct variety. The color designations (color designations are from the R.H.S.
