Abstract: A new and distinct Hybrid Tea Rose plant having attractive large Red flowers.
Claim: I claim:

1. A new and distinct Hybrid Tea Rose plant of the variety substantially as shown and described.
Description: Botanical desgnation: RosaL.


The present invention relates to a new and distinct variety of Rosa L. of the Hybrid Tea rose class, which was created by crossing as seed parent an unnamed, undistributed seedling and as a pollen parent the unpatented variety known as `Tina`. The varietal denomination of this new rose is named `Rutrorap.` The new variety was grown from a grafted cutting in The Netherlands.


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 bud shape and color.

Asexual reproduction by propagation of grafting 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 throughsucceeding propagation.


Among other respects, the new variety differs from its parents in flower color, inasmuch as the seed parent has Pink flowers and the pollen parent has small Yellow flowers whereas the new variety has large Red flowers.


The accompanying illustration shows a typical specimen of 9-month old plants grown in a greenhouse in The Netherlands in the month of November of the new variety depicted in color as nearly true as is reasonably possible to make the same in acolor illustration of this character.


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 theaforementioned 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 September from a grafted cutting.
