USPP9170P - Hybrid Tea rose plant named Tennessee` - Google Patents

Abstract

A new and distinct Hybrid Tea rose plant, particularly distinguished by its continuous production of medium-large, deep orange flowers borne singly on strong, upright stems on a sturdy bush of medium height having good quality 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 "Eliora" as the seed parent with "Cocktail" as the pollen parent (U.S. Plant Pat. No. 1,821). "Eliora" has a yellow color, longer stems, higher production, and has only been for sale in the Netherlands. "Eliora" has not been patented in the U.S.A. "Coctail", has a yellow color, a bigger flower, moderate fragrance, and has longer stems than "Tennessee". "Tennessee" was germinated in 1985, in De Kwakel, The Netherlands. The plant is the result of breeding efforts carried on by me since 1984 in a specific breeding area in a greenhouse in De Kwakel, The Netherlands. The new plant resulted from my breeding efforts to improve quality, production, and vase life (improvement in comparison with the existing commercial available varieties) and to find new colors. The plant has been asexually reproduced by cuttings and grafting. "Tennessee" has been in commerce in The Netherlands since 1988. "Tennessee" has been commercially introduced in the United States in September 1993. Of the many cultivars known to me, there is no cultivar sufficiently similiar to "Tennessee" so as to provide a meaningful basis for comparison. All characteristics or defining features of the plant are faithfully reproduced and transmitted from one generation to the next and appear to be firmly fixed without any instability. Among the novel characteristics possessed by the new variety which distinguish it from its parents and all other varieties of which I am aware are:

(1) medium-large distinct deep orange flowers

(2) continuous production of flowers (whole year round)

(3) strong dark green upright flower stem

(4) upright plant of medium height with good quality foliage

The accompanying drawing shows typical specimens of the vegitative 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 color chart, e.g. "28B" is plate "28B" of the Royal Horticultural Society Colour Chart.
