Cultivar Firmness (lb) Minimum SSC (%) Blackamber Z Fortune Friar Royal D Angeleno Betty Anne Z Blackamber plums with TA 0.60% after ripening have a high consumer acceptance. If plums have > 12.0% SSC, TA does not play a role. More Types of Tree Fruit About 70 varieties released per year. 50% of the releases are sub acid types.
