COMPARISONS TO PARENTAL AND COMMERCIAL RASPBERRY VARIETIES

(7) When DrisRaspTwelve is compared to the female parent RB608.1 (unpatented), DrisRaspTwelve produces fruit that is sweeter and larger in size than that of RB608.1. Additionally, plants of DrisRaspTwelve produce fruit that holds and ships better as compared to fruit produced by RB608.1 plants.

(8) When DrisRaspTwelve is compared to the male parent RD150.1 (unpatented), DrisRaspTwelve produces fruit that is sweeter and larger in size than that of RD150.1. Additionally, plants of DrisRaspTwelve produce fruit that holds and ships better as compared to fruit produced by RD150.1 plants.

(9) When DrisRaspTwelve is compared to the commercial variety DrisRaspThree (U.S. Plant Pat. No. 23,477), DrisRaspTwelve produces fruit with a trapezoidal shape that is glossier and firmer than the fruit with an ovate (broad conical) shape produced by DrisRaspThree plants. Additionally, DrisRaspTwelve produces longer and broader terminal leaflets with a dark green color on the upper side, while DrisRaspThree produces shorter and narrower terminal leaflets with a medium green color on the upper side. Moreover, DrisRaspTwelve produces plants with a semi-upright growth habit, while DrisRaspThree produces plants with an upright growth habit.

(10) DrisRaspTwelve differs from the commercial variety Driscoll Maravilla (U.S. Plant Pat. No. 14,804) in that DrisRaspTwelve produces longer and broader terminal leaflets with a darker green color on the upper side than that of Driscoll Maravilla. Additionally, DrisRaspTwelve has free lateral leaflets, while Driscoll Maravilla has overlapping lateral leaflets. Moreover, DrisRaspTwelve produces fruit with a trapezoidal shape that has weak adherence to the receptacle, while Driscoll Maravilla produces fruit with an ovate (broad conical) shape that has medium adherence to the receptacle.
