COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

(9) DrisStrawSeventySeven differs from the proprietary female parent 92T351 (unpatented) in that DrisStrawSeventySeven has earlier yields, produces fruit that are sweeter, firmer, and more aromatic, and has better rain tolerance as compared to 92T351.

(10) DrisStrawSeventySeven differs from the proprietary male parent 69U144 (unpatented) in that DrisStrawSeventySeven has earlier yields, produces fruit that are sweeter, firmer, and more aromatic, and has better rain tolerance as compared to 69U144.

(11) DrisStrawSeventySeven differs from the commercial variety DrisStrawTwentySeven (U.S. Plant Pat.
