| Abstract: |
A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms elegant long lasting double blossoms which are scarlet pink on the inside and light carmine rose on the outside. The buds are large and of good form. The plant exhibits vigorous vegetation and is well suited for forcing and cut flower production. The plant forms dense and glossy foliage and is not particularly affected by cryptogamic diseases. |
| Claim: |
I claim:
1. A new and distinct variety of Hybrid Tea rose plant characterized by the following combination of characteristics:
(a) forms in abundance elegant long lasting blossoms which are scarlet pink on the inside and light carmine rose on the outside,
(b) is well adapted for forcing,
(c) exhibits vigorous glossy vegetation, and
(d) is particularly suited for cut flower production;
substantially as herein shown and described. |
| Description: |
SUMMARY OF THE INVENTION
The new variety of Hybrid Tea rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., theseed parent) of the new variety was the Jofitali variety (U.S. Plant Pat. No. 4,083). The male parent (i.e., the pollen parent) was the Happiness variety (U.S. Plant Pat. No. 911). The parentage of the new variety can be summarized as follows:
The seeds resulting from the above pollination were sown in a greenhouse and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the newvariety.
It was found that the new variety of Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:
(a) forms in abundance elegant long lasting blossoms which are scarlet pink on the inside and light carmine rose on the outside,
(b) is well adapted for forcing,
(c) exhibits vigorous glossy vegetation, and
(d) is particularly suited for cut flower production.
The buds are large and of good form.
The new variety well meets the needs of the cut flower industry since the blossoms are highly attractive and are formed in abundance. It also is suited for other horticultural uses.
The new variety has been found to undergo asexual propagation by a number of routes, including budding, grafting, cuttage, etc. The characteristics of the new variety have been found to be strictly transmissable by such asexual propagation fromone generation to another.
The new variety has been named the Keiromo variety.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were two yearsof age and were observed during February while grafted on Rosa indicia and growing in a greenhouse at Cap d'Antibes, France.

DETAILED DESCRIPTION
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on two year old plants made during February while grafted on Rosa indicia understock and growing in agreenhouse at Cap d'Antibes, France. The coloration in common terms precedes reference to the chart.
