COMPARISONS TO PARENTAL AND COMMERCIAL BLACKBERRY VARIETIES

(10) DrisBlackNineteen differs from the proprietary female parent DrisBlackFive (U.S. Plant Pat. No. 24,701) in that DrisBlackNineteen has higher vigor compared to DrisBlackFive. Moreover, DrisBlackNineteen differs from the proprietary female parent DrisBlackFive in that DrisBlackNineteen has absent or very weak anthocyanin coloration on dormant cane, palmate type of leaf, medium ovate shaped fruit in longitudinal section, and fruiting on previous year's cane only. In contrast, DrisBlackFive has strong anthocyanin coloration on dormant cane, odd-pinnate type of leaf, long conical shaped fruit in longitudinal section, and fruiting on both previous year's cane and current year's cane.

(11) DrisBlackNineteen differs from the proprietary male parent BL481.3 (unpatented) in that DrisBlackNineteen is spiny while BL481.3 is spineless. Moreover, DrisBlackNineteen has higher yield potential than BL481.3.

(12) DrisBlackNineteen differs from commercial variety Tupy (also spelled Tupi, unpatented) in that DrisBlackNineteen has absent or very weak anthocyanin coloration on young shoot during rapid growth, absent or few number of glandular hairs on young shoot, a V shape of terminal leaflet in cross-section, and a medium ovate fruit shape in longitudinal section. In contrast, Tupy has medium to strong anthocyanin coloration on young shoot during rapid growth, medium number of glandular hairs on young shoot, a U shape of terminal leaflet in cross-section, and a circular to medium ovate fruit shape in longitudinal section.

(13) DrisBlackNineteen differs from commercial variety DrisBlackSeventeen (U.S. Plant Pat. No. 31,291) in that DrisBlackNineteen has a predominant distribution of branches over whole length of dormant cane, an downwards attitude of spine apex in relation to cane, absent or few glandular hairs on young shoot, and early beginning of fruit ripening on previous year's cane. In contrast, DrisBlackSeventeen has a predominant distribution of branches only on upper half of dormant cane, an upwards attitude of spine apex in relation to cane, many glandular hairs on young shoot, and medium beginning of fruit ripening on previous year's cane.
