Abstract

A new and distinct chrysanthemum plant named ‘Zanmubonita Yellow’ is disclosed, it is characterized by its medium sized, double type blooms with yellow color ray florets and response time of 7 weeks. The new plant is normally used for commercial cut flower production.

Description

Description

Botanical designation: Chrysanthemum x morifolium Ramat.

Cultivar denomination: ‘Zanmubonita Yellow’.

RELATED CULTIVARS

‘Zanmubonita Yellow’ is a mutant plant of ‘Zanmubonita’ (unpatented).

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of chrysanthemum, botanically known as Chrysanthemum x morifolium, and referred to by the denomination ‘Zanmubonita Yellow’; the description is based on plants of about 10 weeks old.

‘Zanmubonita Yellow’ is a product of a breeding and selection program to produce new chrysanthemum cultivars for cut flower commercial applications. The new plant cultivar is a naturally whole plant mutant of a parent chrysanthemum named ‘Zanmubonita’ (unpatented).

A comparison with the parent is made in the section ‘DESCRIPTION OF THE INVENTION’ below. The new cultivar was discovered as a whole plant mutation in June 2014 by Henricus Cornellius Maria Jacobs in a controlled environment (greenhouse) in Valkenburg Z-H, The Netherlands. The first act of asexual reproduction of ‘Zanmubonita Yellow’ was accomplished when vegetative cuttings were taken from the initial selection and propagated further in Valkenburg Z-H, The Netherlands.

SUMMARY OF THE INVENTION

The present invention is a new and distinct variety of a cut type chrysanthemum bearing medium sized double type blooms with yellow ray-florets and a response time of seven weeks.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum (of about 10 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 cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants grown in August to September 2016 in a greenhouse in Valkenburg Z-H, the Netherlands in a photo-periodic controlled crop under conditions generally used in commercial practice. The greenhouse temperatures during this crop were at day-time between 18° C. and 25° C. and at night 20° C. After a long day period of 14 days the photo-periodic response time in this crop was 49 days. After the long day period to flowering growth retardants (Alar) were applied 2 to 3 times in an average dose of 2.5 gram/liter water. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought resistance. This new variety of chrysanthemum has been found to retain its distinctive characteristics throughout successive propagations however the phenotype may vary significantly with variations in environment such as light intensity and temperature.

From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Zanmubonita Yellow’ is ‘Zanmubonita’. When ‘Zanmubonita’ and ‘Zanmubonita Yellow’ are being compared the following differences and similarities are noticed: The difference of ‘Zanmubonita’ and ‘Zanmubonita Yellow’ is ray floret color. For that characteristic ‘Zanmubonita Yellow’ has been selected out of ‘Zanmubonita’; ray florets of ‘Zanmubonita Yellow’ are yellow, while those of ‘Zanmubonita’ are white. All other characteristics of ‘Zanmubonita’ and ‘Zanmubonita Yellow’ are similar. A second similar variety is ‘Sunny Eurobelle’ (unpatented), which differs in inflorescence size with ‘Zanmubonita Yellow’. Inflorescences of ‘Sunny Eurobelle’ are smaller in size than those of ‘Zanmumbonita Yellow’.

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