USPP21164P2 - Chrysanthemum plant named ‘Zanmusundown’ - Google Patents

Abstract

A chrysanthemum plant named ‘Zanmusundown’ characterized by its medium sized blooms with yellow ray florets and prolific branching; natural season flower date October 6–10; blooming for a period of 5 weeks.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×morifolium Ramat., and hereinafter referred to by the cultivar denomination ‘Zanmusundown’. ‘Zanmusundown’ is a product of a breeding and selection program for outdoor pot mums (garden mums) which had the objective of creating new chrysanthemum cultivars with a double type inflorescence, a natural season flower date starting at October 6–10; blooming for a period of 5 weeks. ‘Zanmusundown’ is a seedling resulting from the crossing of the female parent id 2824 and male parent id 4678. Plants of ‘Zanmusundance’ differ from plants of the parents in ray-floret color; that of the seedling is yellow, while that of the female parent is white, and of the male parent pink.

The new and distinct cultivar was discovered and selected as a flowering plant by Wilhelmus Bernardus Blom on a cultivated field in Rijsenhout, The Netherlands in 2004. The first act of asexual production of ‘Zanmusundown’ was accomplished when vegetative cuttings were used from the initial selection in 2004 and propagated further in a controlled environment in Rijsenhout, The Netherlands. The new cultivar has been found to retain its distinctive characteristics through successive propagations.

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 various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants grown out door in Rijsenhout, The Netherlands under natural day length and temperature and planted in week 22 in 2008. The natural blooming date of this crop was October 6–10. The average height of the plants was 25 cm. No growth retardants were used. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought tolerance. This new variety produces medium sized blooms with yellow ray florets blooming for a period of 5 weeks.

From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Zanmusundown’ is ‘Zanmusundance’ (U.S. Plant patent application Ser. No. 12/314,958). When ‘Zanmusundance’ and ‘Zanmusundown’ are being compared the following differences are noticed: The difference of ‘Zanmusundance’ and ‘Zanmusundown’ (1) Plant size. And (2) Flower color (1) The plants of ‘Zanmusundance’ are larger than those of ‘Zanmusundown’ (2) The flowers of Zanmusundance' are more soft yellow than those of ‘Zanmusundown’.

The following is a description of the plant and characteristics that distinguish ‘Zanmusundown’ 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 Color Chart, edition 2001.
