Abstract

A chrysanthemum plant named ‘Zanmuday’ characterized by its medium sized blooms with yellow ray florets and prolific branching; natural season flowering date October 8 (week 41); blooming for a period of 5 weeks.

Description

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmuday’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×morifolium Ramat., commercially known as a garden mum, and hereinafter referred to by the cultivar denomination ‘Zanmuday’. ‘Zanmuday’ is a product of a breeding and selection program for outdoor pot mums (garden mums) which had the objective of creating new cultivars with a double type inflorescence, a natural season flowering date around October 8 (week 41), blooming for a period of 5 weeks. ‘Zanmuday’ is a seedling resulting from a cross of the female parent id 24636 with the male parent id 26443. Plants of the new cultivar ‘Zanmuday’ differ from plants of the female parent in inflorescence size; the inflorescences of the seedling are larger than those of the female parent. Plants of the new cultivar ‘Zanmuday’ differ from plants of the male parent in natural-season flowering date; plants of the seedling flower in an earlier period than those of the male parent.

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 2007. The first act of asexual production of ‘Zanmuday’ was accomplished when vegetative cuttings from the initial selection in 2007 were 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 23 in 2005. The natural blooming date of this crop was October 8 (week 41) . The average height of the plants was 35 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 ‘Zanmuday’ are ‘Zanmugoldru’ (U.S. Plant Pat. No. 20,462) and ‘Zanmugolmine’ (U.S. Plant Pat. No. 22,618). When ‘Zanmuday’, ‘Zanmugoldu’ and ‘Zanmugolmine’ are being compared the following differences are noticed: (1) Plant vigor. And (2) Natural season flowering date. (1) Plants of ‘Zanmuday’ are slightly less vigorous than those of ‘Zanmugoldru’, and more vigorous than those of ‘Zanmugolmine. (2) Plants of ‘Zanmuday’ and of ‘Zanmugoldru’ flower later in the season than those of ‘Zanmugolmine’.

The following is a description of the plant and characteristics that distinguish ‘Zanmuday’ 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.
