COMPARISONS TO PARENTAL AND COMMERCIAL RASPBERRY VARIETIES

(7) DrisRaspFifteen differs from the female parent RD335.8 (unpatented) in that fruit of DrisRaspFifteen has a lighter color and an improved appearance when compared with fruit of RD335.8.

(8) DrisRaspFifteen differs from the male parent Z367.1 (unpatented) in that fruit of DrisRaspFifteen has a larger size, a lighter color, and better shelf life when compared with fruit of Z367.1.

(9) DrisRaspFifteen differs from the commercial raspberry variety DrisRaspSix (U.S. Plant Pat. No. 25,044) in that plants of DrisRaspFifteen have an arching growth habit, whereas plants of DrisRaspSix have a semi-erect growth habit. Moreover, DrisRaspFifteen has a convex profile in cross section of leaflets and a free relative position of lateral leaflets, whereas DrisRaspSix has a flat (straight) profile in cross section of leaflets and an overlapping relative position of lateral leaflets. Further, DrisRaspFifteen has a conical fruit shape, whereas DrisRaspSix has an ovate (broad conical) fruit shape.

(10) DrisRaspFifteen differs from the commercial raspberry variety Driscoll Maravilla (U.S. Plant Pat. No. 14,804) in that plants of DrisRaspFifteen have an arching growth habit, whereas plants of Driscoll Maravilla have a semi-erect growth habit. Moreover, DrisRaspFifteen has predominantly three leaflets and a free relative position of lateral leaflets, whereas Driscoll Maravilla has predominantly five leaflets and an overlapping relative position of lateral leaflets. Further, DrisRaspFifteen has a conical fruit shape, whereas Driscoll Maravilla has an ovate fruit shape. In addition, spines of DrisRaspFifteen have a brownish purple color, whereas spines of Driscoll Maravilla have a purple color.
