Hybrid tea rose plant named Hadsatin

Abstract

A new rose variety of the Hybrid Tea class characterized by having large well formed peach/pink flowers on a thornless bush with glossy foliage.

Description

The present invention relates to a new and distinctive variety of rose plant of the Hybrid Tea class, which was originated by my crossing `Smooth Lady` U.S. Plant Pat. No. 6,147 as the seed parent with `Smooth Sailing` as the pollen parent.

Among the novel characteristics possessed by the new variety which distinguish it from:

(a) All other varieties of which I am aware are:

(1) Stems without thorns.

(2) A very floriferous plant.

(3) Peach/pink flowers with 35-40 petals.

(4) Very disease resistant and vigorous.

(b) Seed parent: Pink flowers, 22-24 petals which quill.

(c) Pollen parent: Cream flowers.

Asexual reproduction of the new rose variety by budding, as performed at Tulare, Calif., shows that the aforementioned and all other distinctive characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (RHSCC). The terminology used in the color description herein refers to plate numbers in the aforementioned colour chart, e.g., "53A" is plate "53A" of The Royal Horticultural Society Colour Chart.

Seed parent.--`Smooth Lady`, U.S. Plant Pat. No. 6,147.
