COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

[0083] DrisStrawSixtyTwo differs from the proprietary female parent 73P176 (unpatented) in that DrisStrawSixtyTwo has a bearing that is partially remontant, whereas 73P176 is a short day variety. Moreover, fruit of DrisStrawSixtyTwo have a sweeter flavor and are less firm than fruit of 73P176.

[0084] DrisStrawSixtyTwo differs from the proprietary male parent 107P249 (unpatented) in that plants of DrisStrawSixtyTwo have a stronger vigor and produce higher yields of fruit than plants of 107P249. Moreover, fruit of DrisStrawSixtyTwo are larger in size with a less sweet taste than fruit of 107P249.

[0085] DrisStrawSixtyTwo differs from the commercial variety DrisStrawTwentySeven (U.S. Plant Pat. No. 23,400) in that plants of DrisStrawSixtyTwo have absent or weak leaf blistering, while plants of DrisStrawTwentySeven have medium leaf blistering. Additionally, plants of DrisStrawSixtyTwo have large flowers that are positioned level with foliage, while plants of DrisStrawTwentySeven have medium flowers that are positioned above foliage. Moreover, DrisStrawSixtyTwo has a terminal leaflet margin that is crenate, a fruit shape that is cylindrical, position of achenes that is level with surface of fruit, a medium width of band without achenes, position of calyx attachment that is level with fruit, and is moderately resistant to botrytis fruit rot and Xanthomonas fragariae; whereas DrisStrawTwentySeven has a terminal leaflet margin that is serrate, a fruit shape that is conical, position of achenes that is below surface of fruit, a very broad width of band without achenes, position of calyx attachment that is above fruit, is susceptible to botrytis fruit rot, and is moderately susceptible to powdery mildew.

[0086] DrisStrawSixtyTwo differs from the commercial variety Driscoll El Dorado (U.S. Plant Pat. No. 16,238) in that DrisStrawSixtyTwo has a spreading growth habit and medium dense foliage, while Driscoll El Dorado has a semi-upright growth habit and dense foliage. Additionally, leaves of DrisStrawSixtyTwo have absent or weak leaf blistering, while leaves of Driscoll El Dorado have strong leaf blistering. Moreover, DrisStrawSixtyTwo has a terminal leaflet base that is obtuse in shape, hairs on petiole that have an attitude that is horizontal, fruit that is cylindrical in shape, position of achenes that is level with surface of fruit, and is moderately resistant to botrytis fruit rot; while Driscoll El Dorado has a terminal leaflet base that is rounded in shape, hairs on petiole that have an attitude that is upwards to outwards, fruit that is conical in shape, position of achenes that is below the surface of fruit, and is susceptible to botrytis fruit rot.
