COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

(8) DrisStrawSeventyFive differs from the proprietary female parent 54S259 (unpatented) in that DrisStrawSeventyFive has a less dense canopy, larger fruit size, and longer trusses compared to 54S259.

(9) DrisStrawSeventyFive differs from the male parent DrisStrawFiftySix (U.S. Plant Pat. No. 29,731) in that DrisStrawSeventyFive has an upright plant growth habit, inflorescence above foliage, an overlapping arrangement of petals, and a partially remontant type of bearing, whereas DrisStrawFiftySix has a semi-upright to spreading plant growth habit, inflorescence on the same level as foliage, a touching arrangement of petals, and a fully remontant type of bearing.

(10) DrisStrawSeventyFive differs from the commercial variety DrisStrawTwentyOne (U.S. Plant Pat. No. 23,506) in that DrisStrawSeventyFive has inflorescence above foliage, an acute shape of base of terminal leaflet, a serrate to crenate margin of terminal leaflet, and a partially remontant type of bearing, whereas DrisStrawTwentyOne has inflorescence beneath foliage, a rounded shape of base of terminal leaflet, a crenate margin of terminal leaflet, and a fully remontant type of bearing.

(11) DrisStrawSeventyFive differs from the commercial variety DrisStrawSixty (U.S. Plant Pat. No. 30,789) in that DrisStrawSeventyFive has an upright plant growth habit, inflorescence above foliage, an acute shape of base of terminal leaflet, and a partially remontant type of bearing, whereas DrisStrawSixty has a semi-upright plant growth habit, inflorescence on the same level as foliage, a rounded shape of base of terminal leaflet, and a fully remontant type of bearing.
