Hybrid tea rose plant named `Tanekiam`

Abstract

Hybrid Tea rose capable of high production of white blooms with elegant bud flower shape on strong, wiry stems having long vase life.

Description

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 two unnamed seedlings.

The primary objective of this breeding was to produce a new rose variety having light pastel pink blooms, high production and a long vase life. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

1. High production in greenhouse (180-200 stems per m.sup.2) of long stemmed roses;

2. Few thorns;

3. Well shaped long lasting cut flower;

4. Strong, wiry stems.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, 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 rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
