Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is related to the plant Carola, U.S. patent application Ser. No. 07/767,546, filed Sept. 27, 1991, a continuation of U.S. patent application Ser. No. 07/387,837, filed Aug. 1, 1989, now abandoned. 
     FIELD OF THE INVENTION 
     The present invention is concerned with a new variety of a Hybrid Tea rose discovered by me and being a mutation of Carola, U.S. patent application Ser. No. 07/767,546, which is a mutation of Deladel (Mme. G. Delbard), U.S. Plant Pat. No. 4,391, issued Mar. 6, 1979. 
     BACKGROUND OF THE INVENTION 
     This mutation was discovered as a branch on a Carola plant in 1990 on a cultivated area in a farm, located in Moshav Ha&#39;yogev, located in Israel Valley, Israel, with an average night temperature of 25° C. in summer and 0°-5° C. in winter, and day temperatures of 30° C. in summer and 15° 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 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 of performed at Moshav Ha&#39;yogev, Israel. 
     The observations were made between the present invention, the parent plant, Carola, and the grandparent plant, Deladel.

 .sup.1 Royal Horticultural Society of London, England (RHS) Colour Chart 
 .sup.2 Based upon the average sizes of twenty leaves of each variety     
 sampled from plants grown sideby-side under the same roof and conditions 
 in a greenhouse in Moshav Ha&#39;yogev, Israel.                              
 
    
     SUMMARY OF THE INVENTION 
     The present invention provides a hybrid tea rose variety which include the following characteristics which distinguish the new variety from cultivars to which it is related: 
     Distinctly smaller flowers in comparison with Carola and Deladel and 
     Distinctly different color of basal spot of petal in comparison with Carola. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     FIG. 1 represents a typical specimen of the present invention, illustrating a leaf, a flower bud, a flower bud at picking stage, a part of the stem, leaflets, and flowers at various opening stages. 
     FIG. 2 represents a side-by-side comparison of flower size, bud size, color and size of petal, color and size of basal spot between a typical specimen of the present invention, Odem, and the parent variety, Carola. 
    
    
     The colors in the drawings are as true as is 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&#39;yogev, each on its own roots, and being visibly healthy. 
     BOTANICAL DESCRIPTION 
     Based on observations made in Moshav Ha&#39;yogev, Israel, in 1990 and 1991 in a greenhouse.
