Title: Hybrid tea rose plant named ‘JACdouce’

Description:
Genus and species:  Rosa hybrida.    
   Variety denomination: ‘JACdouce’. 
   ORIGIN OF THE INVENTION 
   The present invention relates to a new and distinct variety of a hybrid tea rose plant named ‘JACdouce’ which was originated by me by crossing an unnamed seedling (not patented) with the variety ‘DICjana’ (Elina) (not patented). 
   BACKGROUND OF THE INVENTION 
   The primary objective of this breeding was to produce a new rose variety having the bright flower color of the male parent combined with the higher petal count, vigorous plant and health of the female parent. 
   BRIEF SUMMARY OF THE INVENTION 
   The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:
         1. Bright orange flower color;   2. Thick petals;   3. Long vase life;   4. Upright angular growth;   5. Long cutting stems; and   6. Ability to grow on its own roots.       

   Asexual reproduction of this new variety by rooting cuttings, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. 
   Comparison with Parents 
   ‘JACdouce’ differs from its male parent, ‘DICjana’, in having ten more petals, longer cutting stems and a more angular growth habit. It differs from its female parent in having an orange flower as compared to the light yellow flower of the female parent and in having longer stems, therefore being taller than its parent. 
   Comparison with Similar Variety 
   ‘JACdouce’ differs from ‘JACirst’ (Artistry) (U.S. Plant Pat. No. 10,230) in flower color being more of a bright orange than ‘JACirst’, and in having a longer vase life, 11-12 days versus 8-9 for ‘JACirst’. 

   
     BRIEF DESCRIPTION OF THE ILLUSTRATION 
     The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
