Title: Interspecific tree named ‘Flavor Punch’

Description:
Botanical designation: Interspecific  Prunus  species. 
     Variety denomination: ‘Flavor Punch’. 
     BACKGROUND OF THE VARIETY 
     Field of the Invention 
     In the field of plant genetics, we conduct an extensive and continuing plant-breeding program including the organization and asexual reproduction of orchard trees, and of which plums, peaches, nectarines, apricots, cherries, almonds and interspecifics are exemplary. It was against this background of our activities that the present variety of interspecific tree was originated and asexually reproduced by us in our experimental orchard located near Modesto, Stanislaus County, Calif. 
     PRIOR VARIETIES 
     Among the existing varieties of interspecific trees, which are known to us, and mentioned herein, ‘Sweet Pixzee 2’ Interspecific (U.S. Plant Pat. No. 23,796), ‘Flavor Blast’ Interspecific (U.S. Plant Pat. No. 23,720), ‘Autumn Treat’ Interspecific (U.S. application Ser. No. 13/999,782) and the proprietary non-patented interspecific varieties ‘46MB665’ and ‘162LM246’. 
     STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT 
     Not applicable. 
     ORIGIN OF THE VARIETY 
     The new and distinct variety of interspecific tree consists of the combination of  Prunus salicina, Prunus armeniaca, Prunus avium  and  Prunus persica . It was originated by us in our experimental orchard located near Modesto, Calif. as a first generation cross between ‘Sweet Pixzee 2’ Interspecific (U.S. Plant Pat. No. 23,796) and our proprietary non-patented interspecific seedling selection with the field identification number ‘46MB665’. The non-patented interspecific pollen parent (46MB665) originated from crosses between our proprietary non-patented interspecific seedling selection ‘162LM246’ and ‘Autumn Treat’ (U.S. Plant Pat. No. 26,192). A large number of these first generation seedlings were budded onto older established trees of ‘Nemaguard’ Rootstock (non-patented) to enhance earlier fruit production. Under close and careful observation the present seedling exhibited desirable fruit and tree characteristics and was selected in 2009 for additional asexual propagation and commercialization. 
     ASEXUAL REPRODUCTION OF THE VARIETY 
     In 2009 asexual reproduction of the new and distinct variety of interspecific tree was by budding to ‘Nemaguard’ Rootstock (non-patented), as performed by us in our experimental orchard located near Modesto, Calif., and shows that reproductions run true to the original tree and all characteristics of the tree and its fruit are established and transmitted through succeeding asexual propagations. 
     SUMMARY OF THE NEW VARIETY 
     The new and distinct variety of interspecific tree which includes [Plum×Plumcot×Cherry×Plum×Plum Peach]×[Plum×Cherry×Plum×Plumcot] is of large size, vigorous, upright growth and a regular and productive bearer of small to medium size fruit with very good flavor and eating quality. The fruit is further characterized by its firm, yellow flesh, attractive dark red skin color and good storage and shipping qualities. In comparison to its seed parent ‘Sweet Pixzee 2’ Interspecific (U.S. Plant Pat. No. 23,796) the fruit of the new variety is larger in size and is approximately 53 days later in maturity. In comparison to its non-patented proprietary interspecific pollen parent (46MB665) the fruit of the new variety is approximately 17 days later in maturity. In comparison to the commercial variety ‘Flavor Blast’ Interspecific (U.S. Plant Pat. No. 23,720) the fruit of the new variety has a darker red skin color and is approximately 7 days earlier in maturity. 
    
    
     
       DESCRIPTION OF THE PHOTOGRAPH 
       The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new interspecific variety. 
       The illustration shows the upper and lower surface of the leaves, an exterior and sectional view of a single fruit divided in its suture plane to show flesh color, pit cavity and the stone remaining in place. The photographic illustration was taken shortly after being picked (shipping ripe) from a 6 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.

Plant/fruit disease resistance/susceptibility: No specific testing for relative plant/fruit disease resistance/susceptibility has been designed. Under close observation during planting, growing, and harvesting of fruit, under normal cultural and growing conditions near Modesto, Calif., no particular plant/fruit disease resistance or susceptibility has been observed. Any variety or selection observed during indexing of plant characteristics with abnormal fungus, bacterial, virus or insect susceptibility is destroyed and eliminated from our breeding program. No atypical resistances/susceptibilities have been noted under normal cultural practices. The present new variety of interspecific, its flowers, foliage and fruit herein described may vary in slight detail due to climate, soil conditions and cultural practices under which the variety may be grown.
