COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

(9) DrisStrawSeventyTwo differs from the female parent UUK 125-001 (unpatented) in that DrisStrawSeventyTwo is more productive, has a lower cull rate (non-marketable fruit), larger fruit size, improved shelf life, and much improved fruit sweetness as compared to UUK 125-001.

(10) DrisStrawSeventyTwo differs from the male parent UUK 143-001 (unpatented) in that DrisStrawSeventyTwo is higher yielding, has a significantly lower cull rate (non-marketable fruit), has a more attractive fruit appearance, and has a significantly improved shelf life as compared to UUK 143-001. Further, DrisStrawSeventyTwo produces darker berries as compared to UUK 143-001. The fruit of DrisStrawSeventyTwo is also marginally sweeter than that of UUK 143-001.

(11) DrisStrawSeventyTwo differs from the commercial variety DrisStrawFiftyFive (U.S. Plant Pat. No. 29,747) in that plants of DrisStrawSeventyTwo have an upright growth habit, whereas plants of DrisStrawFiftyFive have a semi-upright growth habit. Further, plants of DrisStrawSeventyTwo have strong vigor, whereas plants of DrisStrawFiftyFive have medium vigor. Moreover, plants of DrisStrawSeventyTwo have inflorescence on the same level with foliage, whereas plants of DrisStrawFiftyFive have inflorescence beneath foliage. In addition, fruit of DrisStrawSeventyTwo have achenes below surface, whereas fruit of DrisStrawFiftyFive have achenes level with surface. Lastly, DrisStrawSeventyTwo has an improved shelf life as compared to DrisStrawFiftyFive.

(12) DrisStrawSeventyTwo differs from the commercial variety DrisStrawFortyFive (U.S. Plant Pat. No. 27,645) in that plants of DrisStrawSeventyTwo have strong vigor, whereas plants of DrisStrawFortyFive have medium vigor. Further, terminal leaflets of DrisStrawSeventyTwo have a serrate to crenate margin, whereas terminal leaflets of DrisStrawFortyFive have a serrate margin.
