Gerbera plant named Terikatir

Abstract

A new and distinct cultivar of Gerbera plant named Terikatir, characterized by its semi-double flower type and flat flower form, yellow ray floret color, yellow perianth lobes, dark purple disc, and 60-69 mm overall flower diameter.

Description

The present invention comprises a new and distinct cultivar of Gerbera, botanically known as Gerbera jamesonii, and referred to by the cultivar name Terikatir.

Terikatir was originated by applicant from a hybridization made in a controlled breeding program in De Kwakel, The Netherlands in 1988.

The female parent was a cultivar identified as 87.442. The male parent was a cultivar identified as M88.330. The new cultivar was discovered and selected by applicant as one flowering plant within the progeny of the stated parentage in or about January 1989 in a controlled environment in De Kwakel.

The first asexual reproduction of Terikatir was accomplished when vegetative cuttings were taken from the initial selection in April 1989 in a controlled environment in De Kwakel, The Netherlands. Horticultural examination of selected units initiated in November 1989 has demonstrated that the combination of characteristics as herein disclosed for Terikatir are firmly fixed and are retained through successive generations of asexual reproduction. Terikatir is presently being propagated by cuttings and by tissue culture.

Terikatir 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 observations, measurements and comparisons describe plants grown in the greenhouses of Terra Nigra BV in De Kwakel, The Netherlands under controlled conditions which closely approximate those generally used in commercial practice.

The following traits have been repeatedly observed and have been determined to be basic characteristics of Terikatir, which in combination distinguish this Gerbera as a new and distinct cultivar:

1. Semi-double flower type.

2. Flat flower form.

3. Yellow ray floret color.

4. Yellow perianth lobes.

5. Dark purple disc.

6. Overall flower diameter of 60-69 mm.

Of the many commercial cultivars known to the present inventor, there is none which can be meaningfully compared to Terikatir and its unique characteristics.

The accompanying photographic drawing shows typical inflorescence characteristics of Terikatir, with the colors being as nearly true as possible with illustrations of this type. The photograph comprises a closeup view of the flower form and color of the new cultivar.

In the following description, color references are made to The Royal Horticultural Society Colour Chart (RHS). The color values were determined at approximately 12:00 noon on Nov. 9, 1990 under artificial light at De Kwakel, The Netherlands.
