Description

Botanical designation: Chrysanthemum x morifolium Ramat.

Cultivar denomination: “Zanmudove Yellow”.

RELATED CULTIVARS

The new plant is a flower color mutant of ‘Zanmudove’ (U.S. Plant Pat. No. 24,618)

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum x morifolium Ramat., commercially known as a garden mum, and hereinafter referred to by the cultivar denomination ‘Zanmudove Yellow’. ‘Zanmudove Yellow’ is a product of a breeding and selection program which had the objective of finding flower color mutants from existing parent plants. The new plant comprises a whole plant mutant of the parent Chrysanthemum named ‘Zanmudove’. Plants from the new cultivar ‘Zanmudove Yellow’ differ from plants of the parent in the color of the ray-florets. The ray-florets of the parent are white, while those of the new plant are yellow.

The new plant was discovered as a natural flower color mutant in October 2016 by Sjoukje Heimovaara. The first act of asexual reproduction of ‘Zanmudove Yellow’ was accomplished when after planting of the new variety as a motherplant in November 2016, vegetative cuttings from this motherplant were taken and propagated further in Rijsenhout, the Netherlands. In summer, about 6-8 days are needed to initiate roots in cuttings of the new cultivar, after another 5 days rooted plants are formed. 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 (of about 21 weeks) 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 new cultivar in full bloom.

FIG. 2 shows the various stages of blooms 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 in the period of 19 to 25 weeks of age grown outdoors in Rijsenhout, the Netherlands, under natural day length and temperature and planted in week 21 in 2018. The natural blooming date of this crop was October 1 (week 40). The average height of the plants was 28 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 resistance. This new variety produces medium sized blooms with light yellow ray florets blooming for a period of five weeks. From the cultivars known to the inventor the most similar existing cultivar in comparison to ‘Zanmudove Yellow’ is ‘Zanmuday’ (U.S. Plant Pat. No. 24,670). When ‘Zanmuday’and ‘Zanmudove Yellow’ are compared the following differences are noticed: Ray-florets of Zanmuday' are white, while those of ‘Zamudove Yellow’ are light yellow.

The following is a description of the plant and characteristics that distinguish ‘Zanmudove Yellow’ 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 2001.
