USPP16843P2 - Chrysanthemum plant named ‘Gedi Three Mil’ - Google Patents

Abstract

A new and distinct Chrysanthemum plant cultivar is disclosed, characterized by white, decorative flowers that naturally bloom in early September. The plant is moderately vigorous, and has a round, slightly spreading growth habit.

Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘Gedi Three Mil’.

BACKGROUND OF THE INVENTION

The new cultivar ‘Gedi Three Mil’ is a product of hybridization of a female parent Chrysanthemum plant variety ‘Gedi One Tar’ (U.S. Plant Pat. No. 13,689) and a male parent Chrysanthemum plant variety ‘Gedi One Ter’ (U.S. Plant Pat. No. 13,885) in a controlled environment. The new cultivar ‘Gedi Three Mil’ was discovered and selected by Dirk Pieters in Oostniewkerke, Belgium in September 1998.

Asexual reproduction of the new cultivar ‘Gedi Three Mil’ by terminal cuttings and tissue culture was performed in a controlled environment 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 Three Mil’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 Three Mil’. These characteristics in combination distinguish ‘Gedi Three Mil’ as a new and distinct Chrysanthemum cultivar:

• • 1. White, decorative flowers.
  • 2. Round, slightly spreading growth habit.
  • 3. Moderate plant vigor.
  • 4. The plant naturally blooms in early September.

Plants of the new cultivar ‘Gedi Three Mil’ are similar to plants of the female parent variety, ‘Gedi One Tar,’ in most horticultural characteristics, however the ray florets of the new cultivar are white, in comparison to the light-yellow colored ray florets of the female parent variety ‘Gedi One Tar.’ Additionally, the new variety ‘Gedi Three Mil’ is taller and has a more spreading growth habit than the female parent variety ‘Gedi One Tar.’

Plants of the new cultivar ‘Gedi Three Mil’ are similar to plants of the male parent variety, ‘Gedi One Ter’ in most horticultural characteristics, however plants of the new cultivar ‘Gedi Three Mil’ have more flowers per flowering branch, and significantly fewer ray florets than plants of the male parent variety ‘Gedi One Ter.’ Additionally, the new variety ‘Gedi Three Mil’ is taller and wider than the male parent variety ‘Gedi One Ter.’

In comparison to the commercially available variety ‘Florence’ (U.S. Plant Pat. No. 13,102), ‘Gedi Three Mil’ has a larger diameter flower which blooms about five days earlier than the comparable variety. Additionally, the new variety ‘Gedi Three Mil’ has about 13 more flowers per flowering branch in comparison to the comparable variety ‘Florence.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Gedi Three Mil’ grown in a 2 gallon container. One cutting was used in the pot. The colors are as nearly true as is reasonably possible in a color representation of this type.
