Title: Miniature rose plant ‘JENindi’

Description:
Latin name of genus and species:  Rosa hybrid  ‘JENindi’. 
     Variety denomination: The new variety is named ‘JENindi’. 
     BACKGROUND OF THE INVENTION 
     The present invention constitutes a new and distinct variety of miniature rose plant, which was developed by artificially pollinating an unnamed seedling(not patent in the U.S.) with an unnamed seedling (not patent in the U.S.). The two parents were crossed in the summer of 1999 and the resulting seed was sown in December, 1999 in a controlled glasshouse environment. Out of these seedlings one seedling was selected, as the new variety and named ‘JENindi’. The new rose may be distinguished from its seed parent, an unnamed seedling, by the following combination of characteristics: 
     1. The unnamed seedling has a breeding background in unnamed seedlings. 
     2. ‘JENindi’ has medium double flowers, while the unnamed seedling has big single flowers. 
     3. ‘JENindi’ has orange-red colored petals, while the unnamed seedling has dark yellow-red petals. 
     The new variety may distinguished from its pollen parent, an unnamed seedling created by the same inventor, by the following combination of characteristics: 
     1. The unnamed seedling has a breeding background in unnamed seedlings. 
     2. ‘JENindi’ has smaller flowers and foliage as compared to the unnamed seedling. 
     3. ‘JENindi’ has orange-red colored petals, while the unnamed seedling has dark pink petals. 
     BRIEF SUMMARY OF THE INVENTION 
     Initial asexual reproduction of ‘JENindi’ by cuttings was first done in Christiansfeld, Denmark. The reproduction was conducted in controlled greenhouse environments. Have here proven to be stabile by propagation with cuttings in several generations. ‘JENindi’ is a low and compact miniature rose with medium vigor. The shelflife has been tested to be medium. 
     The objective of the hybridization of this rose variety for commercial greenhouse culture was to create a new and distinct variety with: 
     1. Uniform and abundant flowers with good keepability; 
     2. Attractive long lasting foliage and compact growth, 
     3. Year round flowering under glasshouse conditions; 
     4. Suitability for production from softwood cuttings in pots.; 
     5. Durable flowers and foliage which make the variety suitable for distribution in the floral industry. 
     This combination of qualities was not present in previously available commercial cultivars of this type and distinguish ‘JENindi’ from all other varieties of which we are aware. The seeds from hybridization were planted in a controlled environment and evaluations were conducted on the resulting plants. ‘JENindi’ was selected by, Svend Jensen, in his development program in Christiansfeld, Denmark.

     DETAILED BOTANICAL DESCRIPTION OF THE VARIETY 
     The following is a detailed description of the Miniature Rose: Rosa hybrid ‘JENindi’. The following observations, measurements, values and comparisons describe plants grown in glass houses in Christiansfeld, Denmark. The age of the observed plants where 11 to 13 weeks after propagation by cuttings, and produced as flowering pot plants in container of 10.5 centimeter in diameter. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used. For a comparison, the nearest existing rose variety is ‘POUfiry’, a rose variety described and illustrated in U.S. Plant Pat. No. 12,484. Chart 1 details several physical characteristics of ‘JENindi’ and ‘POUfiry’.

     DEVELOPMENT 
     Vegetation: Dense. 
     Blooming: Abundant. 
     Aptitude to bear fruit: Poor. 
     Resistance to diseases: Above average resistance to mildew and Botrytis under normal growing conditions in Christiansfeld, Denmark. Hips/seeds has not been observed due to that the plant has never been grown to the stage of seed development, due to the fact, that the variety is developed for use as a flowering pot plant only. 
     Winter hardiness &amp; Drought/heat tolerance: Due to the fact, that this variety is a potted flowering plant, developed for one time use only, the plant is not tested for winter hardiness or drought/heat tolerance.
