Narrative
Fruit: size medium; skin medium dark blue; flesh good flavor; ripens early over short period, about 80% may be harvested at one time; recommended for mechanical harvest. Bush: upright, spreading, with stems originating in a relatively small area; produces only enough new stems to renew plant; self-unfruitful. - Brooks and Olmo Register of Fruit and Nut Varieties. 1997. APS Press. p. 179.Early ripening, concentrated ripening, good flavor. Flowers earlier than Tifblue. Received as Vaccinium ashei. Climax (early season) was released from Georgia in 1974 from a cross of 'Callaway' x 'Ethel' (Brightwell and Draper 1975). Plants are upright-spreading with stems originating in relatively narrow crowns. Plants produce only enough stems to renew the plants. Heavy pruning or taking cuttings for propagation from young plants stunt growth and contributes to plant decline when plants are under stress such as drought, wet feet, etc. Observations have indicated that flower buds require less chilling hours than leaf buds. The chilling requirement of flower buds is 450-500 hours below 45 degrees F. (Austin and Bondari 1987A). Due to the time of flowering, late spring freezes greatly reduced yields. Asthesis to 50% ripe fruit is 78 days. Berries are medium in size, medium to light blue in color, have a small stem scar, excellent firmness, and aromatic flavor. Early ripening, three to five days before 'Woodard'. Ripening is concentrated. About 60% of the berries may be harvested at one time with minimum shriveled or overripe. Later ripening berries have much reduced fruit size, tough skin, and excessive seediness. It has proven to be especially well-adapted to mechanical harvest and is excellent for fresh pack. The average seed number is 73 seeds per berry. -M.E. Austin, 1994. Rabbiteye Blueberries. Ag Science, Inc. Auburndale, FL. p.20.Climax - a 1976 release from the University of Georgia which has concentrated ripening and can be machine harvested for the fresh market. Fruit are medium in size and have a small scar and good flavor. Climax flowers more heavily and reliably than Beckyblue or Bonita. It is highly susceptible to the blueberry gall midge. It requires 450 - 500 chill hours.
