Abstract

A new Chrysanthemum plant named ‘Yogrand Rapids’ particularly distinguished by the light yellow ray florets with a greyed-red center, decorative type, fully double flower, medium green foliage, fast flowering response time, good stem strength, and excellent shelf-life.

Description

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

Varietal denomination: ‘Yogrand Rapids’.

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 ‘Yogrand Rapids.’

‘Yogrand Rapids’ is a product of a planned breeding program. The new cultivar has light yellow ray florets with a greyed-red center, decorative type, fully double flower, medium green foliage, fast flowering response time, good stem strength, and excellent shelf-life.

‘Yogrand Rapids’ originated from a hybridization made in May 2005 in a controlled breeding environment in Salinas, Calif. The female parent was the proprietary, unpatented plant designated ‘YB-A9207’ with bronze two tone flower color, a 9 week flowering response time, and has a taller growing plant habit.

The male parent of ‘Yogrand Rapids’ was an proprietary, unpatented plant identified as ‘YB-A8021’ with red decorative, open centered flowers, an 8 week flowering response time, less vigor, and moderate pollen production.

‘Yogrand Rapids’ was selected as one flowering plant within the progeny of the stated cross in December 2005, grown out doors in a field covered by saran in Fort Myers, Fla.

The first act of asexual reproduction of ‘Yogrand Rapids’ was accomplished when vegetative cuttings were propagated from the initial selection in March 2006 in a controlled environment in Fort Myers, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in March 2006, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Yogrand Rapids’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Yogrand Rapids’ 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 Mar. 24, 2009. ‘Yogrand Rapids’ 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 ‘Yogrand Rapids’ with colors being as true as possible with an illustration of this type. The photographic drawing shows four flowering potted plants of the new variety growing in a five 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 2009 under greenhouse conditions. These plants were started and grown in central coastal California, then shipped to Gilroy, Calif. in April 2009. Plants were grown under conditions which approximate those generally used in commercial potted Chrysanthemum production and were about 10 weeks of age.

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