The new and distinct cultivar described and illustrated herein is to related the cultivar `Saphir`, also know as Tanrikas, of Rosen Tanatu, Matias Tantau Nachfolger. Tanrikas is the subject of U.S. Plant Pat. No. 8,618 to Evers.
FIELD OF THE INVENTIONThe present invention is concerned with a new variety of a Hybrid Tea rose discovered by me and being a mutation of `Saphir`.
BACKGROUND OF THE INVENTIONThis mutation was discovered as a branch of on a `Saphir` plant in 1993 on a cultivated area in a farm, located in Moshav Ha'yogev, located in Izra'el Valley, Israel with an average night temperature of 25.degree. C. in summer and 0.degree.-5.degree. C. in winter.
The branch was vegetatively propagated from cuttings by self-rooting. From these cuttings plants were grown in a green house where they were further vegetatively propagated from cuttings by self-rooting.
The resulting plants were found to be stable in their botanical characteristics, as are described below and as illustrated by typical plants parts in the attached photographs.
Asexual propagative of this new variety was performed at Moshav Ha'yogev, Israel.
The presently claimed cultivar was a natural mutation of the cultivar Saphir. The data in the following table of comparison is based on observations made in the greenhouse at Moshav Ha'yogev, where plants were grown side-by-side, under the same conditions and under the same roof. The following observations were made between the present invention and the parent plant.

BRIEF DESCRIPTION OF THE DRAWINGSSheet 1 represents a typical specimen of the present invention, illustrating a flower bud at picking stage, a petal, a part of the stem, leaflets, and flowers ar various opening stages;
Sheet 2 represents a side-by-side comparison of the flower size, bud size and color of petal between a typical specimen of the present invention, `Carsoof` (on the left), and the parent variety, `Saphir` (on the right); and
Sheet 3 represents a typical specimen of typical petals and other parts of a flower of the present invention.
The colors in the drawings are as true as reasonably possible in an illustration, depicting green and red colors. The photographs were taken from comparable specimens, grown under exactly the same conditions, in a greenhouse at Moshav Ha'yogev, each on its own roots, and being visibly healthy.
