USPP22619P2 - Chrysanthemum plant named ‘Zanmustone’ - Google Patents

Abstract

A chrysanthemum plant named ‘Zanmustone’ characterized by its medium sized blooms with yellow ray florets and prolific branching; natural season flower date August 17 (week 34); blooming for a period of 5 weeks.

Description

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmustone’.

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 ‘Zanmustone’. ‘Zanmustone’ 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 August 17 (week 34), blooming for a period of 5 weeks. ‘Zanmustone’ is a seedling resulting from a cross of the female parent id 21570 with an unknown male parent. Plants of the new cultivar ‘Zanmustone’ differ from plants of the female parent in the natural season flowering date. The plants of the female parent flower at the end of September, while those of the seedling flower in mid-August.

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 2005. The first act of asexual production of ‘Zanmustone’ was accomplished when vegetative cuttings from the initial selection in 2005 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 2009. The natural blooming date of this crop was August 17 (week 34). The average height of the plants was 20 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 ‘Zanmustone’ is ‘Zanmugolmine’ (U.S. Plant Patent applied). When ‘Zanmugolmine’ and ‘Zanmustone’ are being compared the following difference is noticed: The differences of ‘Zanmugolmine’ and ‘Zanmustone’ are (1) Color ray-floret. And (2) Plant size. (1) The ray-florets of ‘Zaumustone’ are more intensely yellow colored than those of ‘Zanmugolmine’. (2) The plants of ‘Zanmustone’ are slightly larger than those of ‘Zanmugolmine’.

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