| Abstract: |
A new and distinct cultivar of Gerbera plant named `Tertono` as illustrated and described, characterized by its semi-double type, a very distinct dark pink ray floret with white edges, a green disc floret, the outermost florets of which display white stigmas and the middle flowers of which show yellow anthers, pink perianth lobe color and 110 mm overall flower diameter. |

| Description: |
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Gerbera jamesonii, referred to by the cultivar name `Tertono`. `Tertono` was originated from a hybridization program in De Kwakel, The Netherlands in 1989. The female parent was`83.740`, and the male parent was `86.303`. The female parent `83.740` differs from `Tertono` by its orange color, its very high productivity, and its good vase-life. `83.740` has not been patented in the United States. It has been available to othersoutside the company. The male parent `86.303` differs from `Tertono` by its different pink color (more lilac), its reasonable productivity, and its smaller diameter. `86.303` has not been patented in the United States. It was not available to othersoutside the company. The new cultivar was selected by me from the progeny of the stated parentage on or about November 1989. The first asexual reproduction of `Tertono` was accomplished when vegetative cuttings for tissue culture initiation were takenon November 1989 in De Kwakel, The Netherlands. The new cultivar is presently being propagated by cuttings and tissue culture. Horticultural examination of selected units initiated November 1989 has demonstrated that the combination of characteristicsas herein disclosed for `Tertono` are firmly fixed and are retained through successive generations of asexual reproduction.
The following observations, measurements and comparisons describe plants grown in De Kwakel, The Netherlands, under greenhouse conditions which closely approximate those generally used in commercial practice. The following traits have beenrepeatedly observed and are determined to be basic characteristics of `Tertono`, which in combination distinguish this Gerbera from its parents and all other varieties of which I am aware:
1. Type: Semi-double
2. Color of ray floret: Distinctive dark pink
3. Color of disc floret: Green
4. Color of perianthy lobe: Pink
5. Diameter of flower head: Large (approx. 110 mm)
Of the many commercial cultivars known to me, there is no cultivar similar in comparison to `Tertono`.
BRIEF DESCRIPTION OF THE FIGURE OF THE DRAWING
The accompanying photographic drawing shows typical inflorescence characteristics nearly true as possible. In the following description, color references are made to The Royal Horticultural Society Color Chart (RHS). The color values weredetermined at approximately 14:15 p.m. on Sep. 11, 1993 under natural light at De Kwakel.
