Technical Abstract: Fruit of five Jaboticaba (Myrciaria caulifloria) cultivars ‘MC-05-06’, ‘MC-05-14’, ‘MC-05-12’, ‘MC-06-15,’ and ‘MC-06-14’ were evaluated and characterized at the National Germplasm Repository, Subtropical horticulture Research Station (SHRS) Miami, Florida. Thirty fruits were harvested from clonal accessions during March and April, 2013 and2014 and allowed to ripe at room temperature (24-29 oC). Physical characteristic of fruit were determined by measuring fruit length, diameter and weight. Jaboticaba physio-chemical characteristics were determined by measuring the BRIX (°Bx), pH, tritatable acid, and fruit color (L*, a*, b*) values. The average mean fruit weight ranged from 4.02 to 7.0 for ‘MC-05-06 ’ ; 3.5 to 9.9 for MC-05-14; 3.34 to 7.0 for ‘MC-05-14’ for ‘MC-05-12’ , 3.25 to 7.5 for ‘MC-06-15’ and 2.76 to 7.5 for ‘MC-06-14’. Mean fruit length ranged from 24.75 to 13.24 mm, diameter was 22.53 mm, and peel weight fluctuated from 0.25 grams to 0.93 grams. The pH ranged from 2.32 to 3.85 and tritatable acidity express as % of citric acid content ranged from 0. 95 to 1.35 being the highest on ‘MC-06-14’ cultivar. Seeds per fruit varied from 1 t0 4 seeds been the lowest on ‘MC-05-06’. This study demonstrated that jaboticaba could be an alternate/potential crop for growers in south Florida.
