Abstract

A new Chrysanthemum plant named ‘Synhony Durango’ particularly distinguished by the yellow-orange ray floret color, large decorative type semi-double flowers, strong stems, good shelf life, dark green foliage, and about an 8 week flowering response time.

Description

Lain name of the genus and species of the plant claimed: Chrysanthemum×morifolium.

Varietal denomination: ‘Synhony Durango’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the variety name ‘Synhony Durango’.

‘Synhony Durango’ is a product of a planned breeding program. The new cultivar has yellow-orange ray floret color, large decorative type semi-double flowers, strong stems, good shelf life, dark green foliage, and about an 8 week flowering response time.

‘Synhony Durango’ originates as a natural whole plant mutation of ‘Yodurango’, U.S. Plant Pat. No. 19,736. ‘Synhony Durango’ was discovered and selected by the inventor as a single flowering plant within a population of the parent cultivar in a field trial in Fort Myers, Fla. in February 2007. The parent cultivar ‘Yodurango’ has orange-bronze ray floret color.

The first act of asexual reproduction of ‘Synhony Durango’ was accomplished when vegetative cuttings were propagated from the initial selection in May 2007 in a controlled environment in Fort Myers, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in May 2007, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Synhony Durango’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Synhony Durango’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada on Oct. 30, 2009 (#09-6765). ‘Synhony Durango’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Chrysanthemum as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Synhony Durango’ with colors being as true as possible with an illustration of this type. The photographic drawing shows 4 flowering potted plants of the new variety growing in a 6 inch pot and a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. in April 2010 under natural light. These plants were started and grown in Nipomo, Calif. and were shipped to California in April. Plants were grown under conditions which approximate those generally used in commercial potted chrysanthemum production. These plants used in the photograph and descriptions were about 10 weeks old.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
