Narrative
Fruit: skin a very light blue; flesh firm; flavor very good; scar very small and dry. Bush: rabbiteye type; vigorous. For many years, the most widely planted rabbiteye blueberry vairiety in the world. - Brooks and Olmo Register of Fruit and Nut Varieties. 1997. ASHS Press. p. 187.Rabbiteye type, vigous, a standard variety, widely adapted. Accounts for over 50% of acreage in rabbiteye blueberries. Received as Vaccinium ashei. Tifblue (mid to late season) was released from Georgia in 1955 from a cross of 'Ethel' x 'Clara' (Brightwell1963). It is still the most popular rebbiteye blueberry cultivar today from the standpoint of appearance, productivity, harvesting, and shipping qualitites. It has become the standard in comparing other rabbiteye selections and cultivars. Plants make vigorous upright growth with small-medium crowns, producing sufficient suckers to replace old stems, and widely adapted. The chilling requirement for flower bud growth is 550-650 hours below 45 degrees F. (Austin and Bondari 1987A). Anthesis to 50% ripe fruit is 86 days. Berries are medium to large, light blue in color , berry firm with a small, dry stem scar. Berries appear to be ripe several days before fully ripe. Fruit cracking can be a problem with very wet soil conditions or after rain. The average seed number is 44 seeds per berry. Much research has been done with 'Tifblue' on fertilization, pruning , and general growth patterns. It grows and produces the best when grown at a soil pH range (4.6 to 5.3). At the extreme soil pH's, plants exhibit nutrient deficiencies. Late freezing temperatures sometimes occur during bloom which injures or kills flowers making them more susceptible to the disease, Botrytis. Sometimes cold injury is less visible, but it may affect the pistil or the ovules destroying the potential of fuit set or reduce the potential berry size. On the other hand, in a season with inadequate chilling, flowering occurs sporadically and fruit size is generally much smaller. What we thought was frost damage in the past may be a lack of pollination. -M.E. Austin, 1994. Rabbiteye Blueberries. Ag Science, Inc. Auburndale, FL p. 22.
