Abstract

A new and distinct Hybrid Tea Rose plant having flowers with yellow cream central petals and greenish outer petals.

Description

Botanical classification: The present invention relates to a new Hybrid Tea Rose, Rosa hybrid.

Variety denomination: The new rose plant has the varietal name ‘RUIZ99925’.

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 as seed parent and pollen parents unnamed, undistributed seedlings. The varietal denomination of this new rose is named ‘RUIZ99925’.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware are its unusual and attractive flowers exhibiting yellow cream central petals and greenish-hued outer petals.

Asexual reproduction by propagation by grafting and vegetative cutting of the new variety as performed in De Kwakel, The Netherlands shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagation.

COMPARISON WITH PARENTS

Among other respects, the new variety differs from its parents in flower color. The seed parent and the pollen parent are unknown; the new variety was discovered as a single seedling in a controlled planting of mixed rose varieties.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying illustration show a typical specimens of the new variety depicted in color as nearly true as is reasonably possible to make the same in a color illustration of this character.

FIG. 1 shows: new growth 1;

leaflets

2, 3, and 4; stem with thorns 5; flowers in different stages of

development

6, 7, 8 and 9; and

reproductive organs

10, 11 and 12.

FIG. 2 shows a flower of the new variety about ⅓ to ½ open.

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.). The terminology used in color description herein refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary with light availability, environmental and cultural conditions.

The following observations are made of 9-month old plants grown in a greenhouse in De Kwakel, The Netherlands during May from a grafted cutting. The plant was grown in a 12 liter pot with a coco peat substrate. Average day temperature was between 20 and 22 degrees Celsius. The plant was gown on its own roots.
