COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

(10) DrisStrawSeventy differs from the proprietary female parent 139T272 (unpatented) in that DrisStrawSeventy is more vigorous and begins production earlier than 139T272. In addition, fruit of DrisStrawSeventy are larger, softer, lighter in color, and have a more consistent and conic shape than fruit of 139T272.

(11) DrisStrawSeventy differs from the male parent and commercial variety DrisStrawTwentyFour (U.S. Plant Pat. No. 23,378) in that DrisStrawSeventy has a semi-upright plant growth habit, inflorescence above foliage, achenes level with fruit surface, and calyx attachment level with fruit, whereas DrisStrawTwentyFour has a spreading plant growth habit, inflorescence beneath foliage, achenes above fruit surface, and calyx attachment raise from fruit. Further, production of DrisStrawSeventy begins a few days later than DrisStrawTwentyFour, and even though early yield of DrisStrawSeventy does not typically reach the level of DrisStrawTwentyFour, DrisStrawSeventy tends to meet or exceed DrisStrawTwentyFour for late and total yield by end of March. Moreover, fruit of DrisStrawSeventy are larger, and has better shelf life and flavor than fruit of DrisStrawTwentyFour.

(12) DrisStrawSeventy differs from the commercial variety DrisStrawSixtyFour (U.S. Plant Pat. No. 30,936) in that DrisStrawSeventy has a semi-upright plant growth habit, an obtuse shape of base of terminal leaflet, a straight shape in cross section of terminal leaflet, and calyx attachment level with fruit, whereas DrisStrawSixtyFour has a spreading growth habit, a rounded shape of base of terminal leaflet, a concave shape in cross section of terminal leaflet, and calyx attachment inserted in fruit.

(13) DrisStrawSeventy differs from the commercial variety DrisStrawFortyNine (U.S. Plant Pat. No. 27,682) in that DrisStrawSeventy has a semi-upright plant growth habit, an obtuse shape of base of terminal leaflet, a straight shape in cross section of terminal leaflet, and calyx attachment level with fruit, whereas DrisStrawFortyNine has a semi-upright to spreading plant growth habit, a rounded shape of base of terminal leaflet, a concave to straight shape in cross section of terminal leaflet, and calyx attachment inserted in fruit.
