Title: New Guinea impatiens plant named ‘Duemagfi’

Description:
Botanical designation:  Impatiens hawkeri.    
     Cultivar denomination: ‘DUEMAGFI’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of New Guinea  Impatiens  plant, botanically known as  Impatiens hawkeri  and hereinafter referred to by the name ‘Duemagfi’. 
     The new  Impatiens  plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new vigorous and uniform New Guinea  Impatiens  plants with large and attractive flowers. 
     The new  Impatiens  plant originated from a cross-pollination made by the Inventor in July, 2007 in Rheinberg, Germany of a proprietary selection of  Impatiens hawkeri  identified as code number F-19-18-07, not patented, as the female, or seed, parent with a proprietary selection of  Impatiens hawkeri  identified as code number F-03-16-515, not patented, as the male, or pollen, parent. The new  Impatiens  plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2010. 
     Asexual reproduction of the new  Impatiens  plant by terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2010 has shown that the unique features of this new  Impatiens  plant are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the new  Impatiens  have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylight and light intensity without, however, any variance in genotype. 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duemagfi’. These characteristics in combination distinguish ‘Duemagfi’ as a new and distinct  Impatiens  plant:
         1. Upright and outwardly spreading growth habit; mounded plant habit.   2. Freely branching habit.   3. Relatively vigorous growth habit.   4. Dark green-colored leaves.   5. Freely and early flowering habit.   6. Large light red-colored flowers.   7. Good garden performance.       

     Plants of the new  Impatiens  can be compared to plants of the female parent selection. Plants of the new  Impatiens  differ primarily from plants of the female parent selection in the following characteristics:
         1. Plants of the new  Impatiens  are more vigorous than plants of the female parent selection.   2. Plants of the new  Impatiens  are more freely branching than plants of the female parent selection.   3. Plants of the new  Impatiens  and the female parent selection differ in flower color.       

     Plants of the new  Impatiens  can be compared to plants of the male parent selection. Plants of the new  Impatiens  differ primarily from plants of the male parent selection in the following characteristics:
         1. Plants of the new  Impatiens  are more vigorous than plants of the male parent selection.   2. Plants of the new  Impatiens  have larger flowers than plants of the male parent selection.       

     Plants of the new  Impatiens  can be compared to plants of New Guinea  Impatiens  ‘Duepetfire’, disclosed in U.S. Plant Pat. No. 11,505. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new  Impatiens  differed primarily from plants of ‘Duepetfire’ in the following characteristics:
         1. Plants of the new  Impatiens  were more vigorous than plants of ‘Duepetfire’.   2. Plants of the new  Impatiens  had smaller leaves than plants of ‘Duepetfire’.   3. Plants of the new  Impatiens  had larger flowers than plants of ‘Duepetfire’.   4. Flowers of plants of the new  Impatiens  were slightly lighter in color than flowers of plants of ‘Duepetfire’.       

    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPH 
       The accompanying colored photograph illustrates the overall appearance of the new  Impatiens  plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new  Impatiens  plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Duemagfi’ grown in a container. 
     
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photograph and following observations, measurements and values describe plants grown in 10.5-cm containers during the summer in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typically used in commercial New Guinea  Impatiens  production. During the production of the plants, night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time about three weeks after planting and were 16 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
