USPP20462P3 - Chrysanthemum plant named ‘Zanmugoldru’ - Google Patents

Abstract

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

Description

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmugoldru’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×morifolium Ramat., commercially grown as a garden mum, and herein after referred to by the cultivar denomination ‘Zanumgoldru’. ‘Zanmugoldru’ 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 flower, a natural season flower date around October 8 (week 41); blooming for a period of 5 weeks. ‘Zanmugoldru’ is a seedling resulting from a crossing of the seed parent id 995 and the pollen parent id 710. Plants of the new cultivar ‘Zanmugoldru’ differ from plants of the parents mainly in natural-season flowering (1) and flower color (2). (1) The plants of the seed parent flower in early season, while those of ‘Zanmugoldru’ in late season. (2) The flowers of the pollen parent are more pale yellow than those of ‘Zanmugoldru’

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 ‘Zanmugoldru’ 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 DeMotte, Ind., USA, under natural day length and temperature and planted in week 25 in 2007. The natural blooming date of this crop was October 8 (week 41) . The average height of the plants was 30 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 small 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 ‘Zanmugoldru’ is ‘Castor’ (U.S. Plant Pat. No. 14,612). When ‘Castor’ and ‘Zanmugoldru’ are being compared the following difference is noticed: The difference of ‘Castor’ and ‘Zanmugoldru’ are (1) Flower size. And (2) Color flower center (1) The flowers of ‘Castor’ are larger in size than those of ‘Zanmugoldru’ (2) The flower center of ‘Zanmugoldru’ are more orange colored than those of ‘Castor’.

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