Chrysanthemum plant named ‘Gedi Two Ylpap’

Abstract

A new and distinct Chrysanthemum plant cultivar is disclosed, characterized by a daisy-type inflorescence, consistent flowering response to short days, blooming consistently after 46 days of short day length, free branching habit, yellow ray florets, a very uniform round growth habit, and a large quantity of blooms per flowering branch.

Description

Latin name of the genus and species: The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum morifolium.

Variety denomination: The new and distinct Chrysanthemum plant is hereinafter referred to by the cultivar name ‘Gedi Two Ylpap’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a naturally occurring mutation on a single branch of the variety ‘Papiro’ (U.S. Plant Pat. No. 12,998). The new cultivar was discovered in cultivation and selected by the inventor in October 1998.

Asexual reproduction of the new cultivar by apical tip cutting and meristem tissue culture was performed 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 Ylpap’ 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 ‘Gedi Two Ylpap’. These characteristics in combination distinguish ‘Gedi Two Ylpap’ as a new and distinct Chrysanthemum cultivar:

1. Daisy-type inflorescence,

2. Consistent flowering response to short days, blooming consistently after 46 days of short day length,

3. Free branching habit,

4. Yellow ray florets,

5. Very uniform round growth habit, and

6. Large quantity of blooms per flowering branch.

Plants of the new cultivar are similar to plants of the parent cultivar, ‘Papiro’ in most horticultural characteristics, however plants of the new cultivar differed from plants of the cultivar ‘Papiro’ primarily in ray floret color.

In comparison to the commercially available variety ‘Gedi YT8’ (U.S. Plant Pat. No. 11,725), ‘Gedi Two Ylpap’ has longer lateral branches, a lighter yellow ray floret color, and more blooms per flowering branch. In addition, no pollen has been detected in observations of the new cultivar.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The photograph shows a plant of ‘Gedi Two Ylpap’ grown in a six-inch container. One cutting was used in the pot.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Oxnard, Calif. during the month of December and January. The age of the observed plants is 71 days from a rooted cutting. The growing temperature ranged from 55° to 68° F. at night to 60° to 75° F. during the day. Measurements and numerical values represent averages of typical flowering types.
