Title: Raspberry plant named ‘RADIANCE’

Description:
Latin name of the genus and species of the plant claimed:  Rubus idaeus.    
   Variety denomination: ‘RADIANCE’. 
   BACKGROUND OF THE INVENTION 
   The present invention relates to a new and distinct fall bearing raspberry variety designated as ‘RADIANCE’. This new variety is a result of a controlled cross made in 1999 between raspberry variety ‘PS-1616’ (unpatented) and raspberry variety ‘PS-1703’ (patented, U.S. Plant Pat. No. 15,151) in an ongoing breeding program. It is unknown as to which parent variety is the seed parent and which parent variety is the pollen parent. The variety is botanically known as  Rubus idaeus.    
   The seedling resulting from the aforementioned cross was asexually propagated by dormant canes in Santa Cruz County, Calif. and was subsequently selected by the inventor from a controlled breeding plot in Watsonville, Calif. in 2001. After its selection, the new variety was further asexually propagated by dormant canes, roots and non-dormant root shoot cuttings in Santa Cruz County, Calif. and San Joaquin County, Calif. The new variety was then extensively tested over the next several years in fruiting fields in Santa Cruz County, Calif. This propagation has demonstrated that the combination of traits disclosed herein as characterizing the new variety are fixed and remain true to type through successive generations of asexual reproduction. 
   BRIEF SUMMARY OF THE INVENTION 
   ‘RADIANCE’ is primarily adapted to the climate and growing conditions of the central coast of California. This region provides the necessary year-round temperatures required for it to produce and maintain a strong vigorous plant and to remain in fruit production from July through December on primocanes and in the ensuing year from May through July on the floricanes. 
   The following traits have been repeatedly observed and are determined to be unique characteristics of ‘RADIANCE’, which in combination distinguish this raspberry plant as a new and distinct variety:
         1. leaf shape ranging from flat to strongly convex;   2. high fruit firmness;   3. excellent fruit flavor;   4. primocane glaucosity ranging from absent to very weak; and   5. brownish purple floricane color.       

   The raspberry varieties that are believed to be most closely related to the new raspberry variety ‘RADIANCE’ are the raspberry variety ‘PS-1049’ (patented, U.S. Plant Pat. No. 10,142), and the raspberry variety ‘PS-1703’ (patented, U.S. Plant Pat. No. 15,151). In comparison to the similar raspberry varieties ‘PS-1049’ and ‘PS-1703’, ‘RADIANCE’ differs by the following combination of characteristics described in Table 1:

     BRIEF DESCRIPTIONS OF THE PHOTOGRAPHS 
     The accompanying color photographs illustrate the overall appearance of typical specimens of the new raspberry variety, ‘RADIANCE’ at various stages of development as true as reasonably possible with color reproductions of this type. Color in the photographs may differ slightly from the color value cited in the detailed botanical description which accurately describes the color of ‘RADIANCE’. The depicted plant and plant parts of the new raspberry variety ‘RADIANCE’ were taken in Watsonville, Calif. and are approximately 2 to 16 months old.

   DETAILED BOTANICAL DESCRIPTION 
   ‘RADIANCE’ has not been observed under all possible environmental conditions. The characteristics of the new variety may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type, and location. 
   The aforementioned photographs, together with the following description of the new raspberry variety ‘RADIANCE’, unless otherwise noted, are based upon observations taken during the 2007-2008 growing season in Watsonville, Calif. Primocane measurements and ratings were taken from plants of ‘RADIANCE’ dug from a nursery located in San Joaquin County, Calif. during the middle of December 2006 and planted approximately 3 to 4 weeks later in Watsonville, Calif. The approximate age of the observed primocane plants is 7 to 8 months. Floricane measurements and ratings were taken from the same planting of ‘RADIANCE’ at an approximate age of 16 to 18 months. Yield observations and fruit quality characteristics are averaged from three years of data collected from the 2002 through 2007 production seasons. Flower measurements and characteristics are from secondary flowers unless otherwise noted. Fruit characteristics and measurements are from secondary fruit unless otherwise noted. Foliage characteristics and measurements are from 3-foliate foliage unless otherwise noted. 
   Color terminology where noted follows the Munsell Book of Colors, Munsell Color, Baltimore, Md. (1976). 
   The following Tables 2-6 describe fruit, plant, foliage, flower and pest/disease characteristics of the new raspberry ‘RADIANCE’ in comparison to the similar raspberry varieties ‘PS-1040’ (patented, U.S. Plant Pat. No. 10,142) and ‘PS -1703’ (patented, U.S. Plant Pat. No. 15,151).
