plant named ‘Yoadelle’

Abstract

A new Chrysanthemum plant named ‘Yoadelle,’ particularly distinguished by the small single white spoon shaped ray florets, compact and short, uniform habit with excellent branching, and dark, glossy small foliage.

Description

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

Varietal denomination: ‘Yoadelle’.

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 ‘Yoadelle’.

‘Yoadelle’ is a product of a planned breeding program. The new cultivar has small single white spoon shaped ray florets, compact and short, uniform habit with excellent branching; dark, glossy small foliage.

‘Yoadelle’ originated from a hybridization made in February 2004 in a controlled breeding environment in Salinas, Calif. The female parent was the proprietary plant designated ‘YB-A0900,’ unpatented, with white daisy spoon flowers. ‘YB-A0900’ has more floriferiousness, is taller and has a less compact habit than ‘Yoadelle’.

The male parent of ‘Yoadelle’ was the proprietary plant designated as ‘YB-A7015,’ unpatented, with white anemone spoon flower form. ‘YB-A7015’ has less floriferiousness and a less compact habit than ‘Yoadelle’.

‘Yoadelle’ was selected as one flowering plant within the progeny of the stated cross in February 2005, grown outdoors in a field covered by saran in Fort Myers, Fla.

The first act of asexual reproduction of ‘Yoadelle’ was accomplished when vegetative cuttings were propagated from the initial selection in May 2005, in a controlled environment in Fort Myers, Fla.

Horticultural examination of plants grown from cuttings of the plant initiated in May 2005, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Yoadelle’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Yoadelle’ 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 in October 2008. ‘Yoadelle’ has not been made publicly available more than one year prior to the filing of this application.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Yoadelle’ with colors being as true as possible with an illustration of this type. The photographic drawing shows 3 flowering potted plants of the new variety, with 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. The plants were started and grown in central coastal California, grown under conditions which approximate those generally used in commercial potted Chrysanthemum production and were about 8-9 weeks of age when shipped to Gilroy, Calif. in April 2009.

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

BRIEF SUMMARY OF INVENTION

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.
