Hybrid tea rose plant named `TANnollipa`

Abstract

A hybrid tea rose plant having distinctive yellow flower buds; bright yellow, large, open flowers on long stems, and good cut flower production.

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 an unnamed seedling, with the variety TANilyks, U.S. Plant Pat. No. 9,065.

The primary objective of this breeding was to produce a new rose variety having the deep yellow flower color and large flower size of the unnamed parent, combined with the very good cut flower production and long stems of the TANilyks parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware.

1. Distinctive, deep yellow-orange bud and bright yellow flower;

2. Good cut flower production;

3. Long, straight stems;

4. Large, open flower;

5. Production of many, seven-leaflet leaves.

TANnollipa is a cut flower, greenhouse produced rose. Its production is 22-24 stems per plant per year with long, strong stems. It has long buds and excellent color of buds and flowers.

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

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.

Parentage:

Seed parent.--Unnamed seedling.

Pollen parent.--TANilyks (U.S. Plant Pat. No. 9,065).
