Hybrid tea rose plant named ‘Panamaril’

Abstract

A new variety of hybrid tea rose plant producing yellow flowers of good form.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distant 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 The Netherlands. The varietal denomination of the new variety is ‘Panamaril’.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety which distinguish it from its parent and all other varieties of which I am aware are its attractive yellow flowers.

Asexual reproduction by budding of the new variety as performed in The Netherlands shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. The new variety has been reproduced through propagation by cuttings, grafting, budding and micropropagation.

BRIEF DESCRIPTION OF ILLUSTRATION

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

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of 9-month old plants 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 guideline. 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 seedlings.

Class: Hybrid Tea.

As can be seen in the accompanying detail illustration there is shown a new shoot, 1; compound three, five and seven leaflet leaves, 2, 3 and 4, respectively; a stem, 5; buds, 6 and 7; a flower, 8, about one-third open to one-half open and a flower, 9, more fully open. Also shown are flower stems 10, 11 and 12, with reproductive organs displayed.

COMPARISON WITH PARENTS

The female parent produces yellow roses, and the male parent produces yellow ochre flowers.

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