Narrative
‘Black Pearl’ is outstanding because it compares favorably to ‘Marion’ for its plant, yield, and fruit characteristics in the field and it appears to produce a similar quality processed product (Finn et al., 2005c). ‘Black Pearl’ was selected in 1995 from a cross of ORUS 1117-11 × ORUS 1122-1 made in 1993 and tested as ORUS 1380-1. ‘Black Pearl’ has been evaluated in blind panels by industry representatives as processed individually quick frozen and pureed products.
As an IQF fruit, ‘Black Pearl’ was ranked better than ‘Marion’, ‘Silvan’, and ‘Waldo’ for color, appearance, and seediness and it was ranked similar to ‘Marion’, but better than ‘Silvan’ and ‘Waldo’, for flavor and overall quality. As a pureed product, ‘Black Pearl’ was ranked similarly to ‘Silvan’, ‘Waldo’, and ‘Marion’ for aroma, flavor, color, and “overall quality”. As with ‘Black Diamond’, consumer panels concluded that, based on flavor, ‘Black Pearl’ should be a good replacement for ‘Marion’ (Kurnianta, 2005). ‘Black Pearl’ is a moderately vigorous plant that produces strong primocanes and, as with ‘Black Diamond’, has inconsequential spines below 0.5 m.
