Latest Yoval Agricultural Products Ltd. Patents:
The new and distinct cultivar described and illustrated herein is related to the cultivar `Carola`, the subject of U.S. Plant Pat. No. 8,290, issued Jul. 6, 1993, which in turn is a mutation of `Deladel` (`Mme. G. Delbard`), the subject of U.S. Plant Pat. No. 4,391, issued Mar. 6, 1979.
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 `Carola`, U.S. Plant Pat. No. 8,290, issued Jul. 6, 1993.
BACKGROUND OF THE INVENTIONThis mutation was discovered as a branch on a `Carola` 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 greenhouse 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 propagation of this new variety was performed at Moshav Ha'yogev, Israel.
The presently claimed cultivar was a natural mutation of the cultivar `Carola`.
All color definitions in this application are taken from The Royal Horticultural Society of London, England (R.H.S.), Colour Chart.
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 DRAWINGS
Sheet 1 represents a typical specimen of the present invention, illustrating a flower bud at picking stage, a part of the stem, leaflets, and flowers at 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, `Light Carola` (on the left) and the parent variety, `Carola` (on the right); and
Sheet 3 represents another side-by-side comparison of various flower parts between a typical specimen of the present invention, `Light Carola` (on the left) and the parent variety, `Carola` (on the right).
The colors in the drawings are as true as is reasonably possible in an illustration, depicting green and red colors. The plants illustrated in Sheets 2 and 3 were grown under exactly the same conditions, in a greenhouse at Moshav Ha'yogev, each on its own roots, and being visibly healthy.

The cultivar is intended as and is suitable as a greenhouse rose. The cultivar bears blooms multiply. Blooms may be borne in a cluster.
When reference is made herein to "Number of flowers few," it is understood that such refers to 3, 4 or 5 flowers per cluster (i.e., the flowers that are left on the flowering shoot after the other flowers were pruned off). In addition, the term "fast" represents: within one month from insertion (of the cutting into the bedding) to a commercial plant. The term "good" represents: about 60-70% success in propagation.
