COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

(8) DrisStrawSeventyOne differs from the proprietary female parent 35T 42 (unpatented) in that DrisStrawSeventyOne has larger fruit compared to 35T 42. Moreover, plants of DrisStrawSeventyOne are more vigorous than plants of 35T 42. Additionally, fruit size of 35T 42 decreases more sharply later in the season than fruit size of DrisStrawSeventyOne.

(9) DrisStrawSeventyOne differs from the proprietary male parent 50T403 (unpatented) in that DrisStrawSeventyOne has smaller, softer, and more uniformly shaped fruit compared to 50T403. Moreover, DrisStrawSeventyOne produces fewer stolons compared to 50T403.

(10) DrisStrawSeventyOne differs from the commercial variety DrisStrawFortyFour (U.S. Plant Pat. No. 26,801) in that DrisStrawSeventyOne has inflorescence beneath foliage, an obtuse shape of base of terminal leaflet, an outwards attitude of fruit sepals, and a partially remontant type of bearing, while DrisStrawFortyFour has inflorescence above foliage, a rounded shape of base of terminal leaflet, an upwards attitude of fruit sepals, and a day neutral type of bearing.

(11) DrisStrawSeventyOne differs from the commercial variety DrisStrawNine (U.S. Plant Pat. No. 20,733) in that DrisStrawSeventyOne has inflorescence beneath foliage, an obtuse shape of base of terminal leaflet, a free arrangement of flower petals, and a partially remontant type of bearing, whereas DrisStrawNine has inflorescence above foliage, a rounded shape of base of terminal leaflet, an overlapping arrangement of flower petals, and a fully remontant type of bearing.
