Hybrid Tea rose plant named `sellobby`

Abstract

A new rose variety of the Hybrid Tea class, characterized by its continuous and profuse production of medium-sized soft pink flowers, borne singly on upright stems on a sturdy bush of medium height, having abundant and glossy foliage and a weak fragrance.

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 "Jacaranda" with an unnamed (SR 85.055) and unpatented seedling.

The primary objective of this breeding was to obtain a new rose variety comparable to that of "Jacaranda" with a smaller in size and more soft pink flower and same fragrancy. While the results achieved a distinct pink hybrid tea rose of smaller size, the new variety did not otherwise correspond to the characteristics of "Jacaranda", 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 the following characteristics which are outstanding in the new variety:

(1) a medium-sized soft pink flower

(2) very rapid flowering cycles

(3) distinctive fragrance

(4) a vigorous upright plant of medium height

(5) very glossy foliage

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 culture as performed in a greenhouse in De Kwakel, the Netherlands, shows that these characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWING

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 by conventional 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 colordescription herein refers to plate numbers in the aforementioned color chart e.g. "53A" is plate "53A of The Royal Horticultural Society Colour Chart.
