Abstract

A new Chrysanthemum plant named ‘Yoyolanda,’ particularly distinguished by the medium to large yellow decorative-type inflorescence; upright, mounded and compact plant habit that is freely branching; and medium to dark green foliage.

Description

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

Varietal denomination: ‘Yoyolanda’.

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 ‘Yoyolanda’.

‘Yoyolanda’ is a product of a planned breeding program. The new cultivar has medium to large yellow decorative-type inflorescence; upright, mounded and compact plant habit that is freely branching; and medium to dark green foliage.

‘Yoyolanda’ originated from a hybridization made in January 2005 in a controlled breeding program in Salinas, Calif. ‘Yoyolanda’ was selected as a single flowering plant within the progeny of the stated cross in October 2005 in a controlled environment in Alva, Fla.

The female parent was the proprietary plant designated ‘Gedi One Ces’ (Cesaro), U.S. Plant Pat. No. 13,797 with larger, more golden-yellow flower color; slightly lighter colored foliage with a larger plant habit.

The male parent of ‘Yoyolanda’ was an unpatented hybrid seedling identified as ‘00-M389’ with lavender flower color. ‘00-M389’ has a smaller plant habit and a faster natural flowering response than ‘Yoyolanda’.

The first act of asexual reproduction of ‘Yoyolanda’ was accomplished when vegetative cuttings were propagated from the initial selection in December 2005 in a controlled environment in Alva, Fla.

BRIEF SUMMARY OF INVENTION

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

‘Yoyolanda’ 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.

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.

Plant Breeder's Rights for this cultivar have not been applied for. ‘Yoyolanda’ 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 ‘Yoyolanda’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering potted plant of the new variety and a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant description and measurements were taken in Salinas, Calif. in late May 2009 under natural light, and the aforementioned photographs were taken in Gilroy, Calif. in late May 2009 in a greenhouse.

These plants were started and grown in six inch pots, in Alva, Fla. and were shipped in mid-May 2009 to California. Plants were grown under conditions which approximate those generally used in commercial potted Chrysanthemum production, including the use of short day/long night treatments and the pinching of terminal apices. These plants used in the photograph and descriptions were about ten weeks old.

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