Chrysanthemum plant named ‘Gedi Two Ama’

Abstract

A new and distinct Chrysanthemum plant cultivar is disclosed, characterized by a spider type flower form having pink/purple ray florets. The new variety is a garden type chrysanthemum, and naturally blooms about the first week of September.

Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘Gedi Two Ama’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of garden-type Chrysanthemum plant, herein after referred to by the cultivar name ‘Gedi Two Ama’. The new cultivar is a product of induced mutation and selection of an unpatented cultivar called ‘Amandola.’ Mutation of ‘Amandola’ was induced by irradiation of unrooted cuttings. The selection from the irradiated cuttings was made by Dirk Pieters in September 2001.

Asexual reproduction of the new cultivar by vegetative cuttings and tissue culture was performed in Staden, Belgium and in Oxnard, Calif., and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Gedi Two Ama’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Ged Two Ama.’ These characteristics in combination distinguish ‘Gedi Two Ama’ as a new and distinct Chrysanthemum cultivar:

1. Garden type Chrysanthemum.

2. Pink/purple ray florets.

3. Spider type flower form.

Plants of the new variety are similar to plants of the source cultivar from which the new variety was derived, ‘Amandola,’ in most horticultural characteristics. However, plants of the new cultivar are taller and have a larger diameter inflorescense than plants of the ‘Amandola’ cultivar. Additionally, the new variety produces more lateral branches, and also produces more flowers per lateral branch than the ‘Amandola’ cultivar. ‘Amandola’ was made by hybridization of a female parent Chrysanthemum plant variety ‘Gedi Two Tar’ (U.S. Plant Pat. No. 13,689) and a male parent Chrysanthemum plant variety ‘Gedi One Jam’ (U.S. Plant patent application Ser. No. 09/863,748), which was performed in September, 1997 by Dirk Pieters. Multiple generations of the resulting ‘Amandola’ cultivar were reproduced and flowered. In January 1999 unrooted cuttings of the cultivar ‘Amandola’ were irradiated, selected, and propagated, producing the final cultivar described in this application.

Plants of the new cultivar are similar to plants of the female grandparent variety, ‘Gedi Two Tar’ in most horticultural characteristics, however plants of the new cultivar have pink/purple ray florets, in contrast to the yellow ray florets of the female parent variety ‘Gedi Two Tar’. Additionally, plants of the new cultivar are taller and have a larger diameter inflorescence than plants of the female parent variety, ‘Gedi Two Tar’. Further, the new variety blooms approximately two weeks earlier than ‘Gedi Two Tar.’

Plants of the new cultivar are similar to plants of the male grandparent variety, ‘Gedi One Jam’ in most horticultural characteristics. However, plants of the new cultivar have a spider-type bloom while the male parent variety, ‘Gedi One Jam’ has a decorative-type bloom. The new variety has a smaller diameter inflorescence than does ‘Gedi One Jam’. Additionally, the new variety is taller and naturally blooms two weeks earlier than the male parent variety, ‘Gedi One Jam.’

In comparison to the commercially available variety ‘Yomaggie’ (U.S. Plant Pat. No. 11,855), ‘Gedi Two Ama’ has more ray florets which have a lighter purple color than the ray florets of ‘Yomaggie.’ Additionally, the inflorescence of the new variety is a spider-type compared to a quilled-daisy type of ‘Yomaggie.’ Further, the new variety has a more rounded plant form and blooms approximately two to three weeks earlier than plants of the commercially available variety ‘Yomaggie.’
