Hybrid tea rose plant named `Panpast`

Abstract

A new variety of hybrid tea rose plant producing light apricot flowers of good form and suitable for growing under glass.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class which was created by crossing undistributed, unnamed and unpatented seedlings as seed and pollen parents in Quito, Ecuador. The varietal denomination of the new variety is `PANPAST`. The new variety was isolated and asexually reproduced by budding in Ecuador.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive light apricot flowers of good form with long stems borne on a floriferous plant and suitable for production of cut flowers under glass. The new variety has been reproduced through propagation by cuttings, grafting, budding and micropropagation.

Asexual reproduction by budding of the new variety as performed in Quito, Ecuador, shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows a typical specimen of the vegetative growth and flower of the new variety depicted in color as nearly true as it is reansonably possible to make the same in a color illustration of this character.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of the new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.) and horticultural terminology in accordance with standard terminology used in UPOV-approved horticultural guidelines. The terminology used in color descriptions herein refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary depending upon growing conditions under different climate, soil, and cultivation conditions.

Parentage: Seed and pollen parents are unnamed seedlings.

Class: Hybrid Tea.

The following further horticultural description is based on observations made of specimens grown under glass in Quito, Ecuador.
