| Abstract: |
A new rose variety of the Hybrid Tea class, characterized by its medium to large sized yellow-cream colored flowers having a mild, honey-like fragrance, said flowers being borne singly on strong, upright stems on a sturdy bush of medium height. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the Hybrid Tea class, substantially as herein shown and described characterized particularly as to novelty by its medium-large yellowflowers, borne singly on strong, upright stems on a sturdy bush of medium height. |
| Description: |
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of rose plant of the Hybrid Tea class, which was originated by me by crossing the variety "Tanja" with an unnamed (SR 85.085) and unpatented seedling.
"Tanja" differs from "Selhafnium" by its orange flower color, smaller flower size, and shorter stems.
The primary objective of this breeding was to obtain a new rose variety comparable to that of "Tanja", but with a larger flower and stronger stems. While the results achieved a distinct yellow Hybrid Tea rose of large size, the new variety didnot otherwise correspond to the characteristics of "Tanja", but nevertheless, achieved a new and distinct combination of characteristics which is desirable and attractive, as well as different from anything heretofore available, as evidenced by thefollowing characteristics which are outstanding in the new variety:
(1) a large yellow flower
(2) rapid flowering cycles
(3) distinctive fragrance
(4) a vigorous upright plant of medium height
(5) a plant which has many thorns on the stems and many little prickles on the peduncle
The foregoing characteristics and distinctions definitely differentiate the new variety from its parents, as well as from all other varieties of which I am aware, and asexual reproduction of the new variety by cuttings, grafting or tissue cultureas performed in a greenhouse in De Kwakel, the Netherlands, shows that these and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
BRIEF DESCRIPTION OF THE DRAWINGS
The new variety of rose plant is illustrated by the accompanying photographic illustrations, of which:
Sheet 1 shows a full face view of the flower and
Sheet 2 shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development. The color renditions are as nearly true as as it is possible to make same in color illustrations of this character byconventional photographic procedures.
The following is a detailed description of this new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color descriptionherein refers to plate numbers in the aforementioned color chart e.g. "53A" is plate "53A" of The Royal Horticultural Society Colour Chart.
