Title: New Guinea Impatiens plant named ‘Misato FG1’

Description:
Genus and species:  Impatiens×hybrida.    
   Variety denomination: ‘Misato FG1’. 
   BACKGROUND OF THE NEW PLANT 
   The present invention comprises a new and distinct cultivar of New Guinea  Impatiens,  botanically known as  Impatiens×hybrida,  and hereinafter referred to by the cultivar name ‘Misato FG1’. ‘Misato FG1’ originated from an interspecific hybridization between  Impatiens ‘ 02-NG2’, an unpatented proprietary orange-flowered  impatiens  breeding line and  Impatiens ‘ 02-NG1’, an unpatented proprietary pink-lilac-flowered  impatiens  breeding line in Misato, Japan. In 2002, the two  Impatiens  species were crossed and a population of F 1  plants was created. 
   The F 1  plants were evaluated in Misato, Japan in 2004 in an open field trial. Criteria for selection included mounding growth habit, tolerance to heat and cold, vigorous rooting, red flower color and overall plant vigor. At the end of the trial, one single-plant selection was made based on the above criteria and vegetatively propagated. The plant was trialed in Athens, Ga. and Salinas, Calif. The selection subsequently was named ‘Misato FG1’ and found to retain its distinctive characteristics through successive asexual propagations. 
   Plant Breeder&#39;s Rights for this cultivar were applied for in Canada on Apr. 19, 2005. No sales or offers for sale of this cultivar were made before Apr. 19, 2005. 
   SUMMARY OF THE INVENTION 
   The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Salinas, Calif.
         1. Red flower color   2. Tolerance to heat and cold   3. Vigorous rooting   4. Overall plant vigor

   DETAILED DESCRIPTION OF THE NEW CULTIVAR 
   The following detailed descriptions set forth the distinctive characteristics of ‘Misato FG1’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. The plant history was taken on plants grown for about four months from propagation by terminal cuttings under greenhouse conditions. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4 th  edition (2001). Anatomic labels are from  The Cambridge Illustrated Glossary of Botanical Terms  by M. Hickey and C. Kink, Cambridge University Press. 
   DETAILED BOTANICAL DESCRIPTION 
   
       
       Classification:
             Family.— Balsaminaceae.     Botanical.—Impatiens  interspecific cross ( Impatiens×hybrida ).     Common name.—Impatiens.          
     
       Parentage:
             Female parent.—‘ 02-NG2’, a proprietary  Impatiens  breeding line (unpatented).     Male parent.—‘ 02-NG1’, a proprietary  Impatiens  breeding line (unpatented).       
     
       Growth:
             Time to produce a rooted cutting.— The terminal 0.1 to 1.5 inches of an actively growing stem was excised. The base of the cuttings were dipped for 1 to 2 seconds in a 1:9 solution of DIP &#39;N GROW (1 solution: 9 water) root-inducing solution immediately prior to sticking into the cell trays. Cuttings were stuck into plastic cell trays having 98 cells and containing a moistened peat moss-based growing medium. The cuttings were misted with water from overhead for 10 seconds every 30 minutes until sufficient roots were formed. The vegetative cuttings were propagated in five to six weeks.     Environmental conditions for plant growth.— Rooted cuttings were transplanted and grown in 20 cm diameter plastic pots in a glass greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium was applied once a day or every other day by overhead irrigation. Pots were top-dressed with a dry, slow release fertilizer containing 20% nitrogen, 10% phosphorus and 18% potassium. The typical average air temperature was 24° C.     Time to bloom from propagation.— 6-8 weeks.
