Abstract

A new Chrysanthemum plant named ‘Yomildred,’ particularly distinguished by the medium to large, white decorative-type flowers, medium size mounded habit, and a later natural season flowering response.

Description

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

Varietal denomination: ‘Yomildred’.

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 ‘Yomildred’.

‘Yomildred’ is a product of a planned breeding program. The new cultivar has medium to large, white decorative-type flowers, medium size mounded habit, and a later natural season flowering response.

‘Yomildred’ originated from a hybridization made in March 2000 in a controlled breeding environment in Salinas, Calif. The seed sowing took place in June 2003 in a controlled environment in Alva, Fla.

The female parent was the unpatented proprietary plant designated ‘97-LO91’ with similar flower type, color and size, a natural season response that is at least 3 days slower, shorter and wider plant habit, and less uniform flowering.

The male parent of ‘Yomildred’ was an unpatented hybrid seedling identified as ‘95-L343008’ with similar flower color and size, fewer disc florets, a natural season response that is at least 2 days slower, a larger plant size, and flowers less uniformly.

‘Yomildred’ was selected as one flowering plant within the progeny of the stated cross in November 2003.

The first act of asexual reproduction of ‘Yomildred’ was accomplished when vegetative cuttings were propagated from the initial selection in December 2003 in a controlled environment in Alva, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in December 2003, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Yomildred’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Yomildred’ 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. ‘Yomildred’ 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 ‘Yomildred’ 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 descriptions and measurements were taken in Salinas, Calif. in early June 2009 under natural light. The aforementioned photographs were taken in Gilroy, Calif. in early June 2009 in a greenhouse. These plants were started and grown in six inch pots in Alva, Fla. and were shipped to California in late May 2009.

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.
