COMPARISONS TO PARENTAL AND COMMERCIAL BLUEBERRY VARIETIES

(9) DrisBlueTwentyTwo differs from the proprietary female parent 196H 3 (unpatented) in that fruit of DrisBlueTwentyTwo have better firmness, picking scar, and shelf life than fruit of 196H 3. Additionally, plants of DrisBlueTwentyTwo mature earlier and are more productive than plants of 196H 3.

(10) DrisBlueTwentyTwo differs from the proprietary male parent 7J301 (unpatented) in that fruit of DrisBlueTwentyTwo have better firmness than fruit of 7J301. Additionally, plants of DrisBlueTwentyTwo mature earlier and are more productive than plants of 7J301.

(11) DrisBlueTwentyTwo differs from commercial blueberry plant variety Snowchaser (U.S. Plant Pat. No. 19,503) in that DrisBlueTwentyTwo has a semi-upright plant growth habit, a green color of one-year-old shoot, an elliptic leaf shape, and an entire leaf margin, whereas Snowchaser has an upright to spreading plant growth habit, a brown color of one-year-old shoot, an ovate leaf shape, and a serrate leaf margin.

(12) DrisBlueTwentyTwo differs from the commercial blueberry plant variety DrisBlueNineteen (U.S. Plant Pat. No. 31,698) in that DrisBlueTwentyTwo has an elliptic leaf shape, ridges absent on corolla tube, an oblate fruit shape in longitudinal section, and reflexed fruit sepals, whereas DrisBlueNineteen has an ovate leaf shape, ridges present on corolla tube, a round fruit shape in longitudinal section, and straight fruit sepals.
