Technical Abstract: A variety trial of 14 different carambola (Averrhoa carambola, L.) cultivars was conducted at the National Germplasm Repository, Subtropical Horticultural Research Station in Miami, FL. The study compared the morphological and physicochemical characteristics of 14 carambola varieties grown at the research station. The research took place over a two year period with the carambola trees grown on a Krome gravely loam soil. In both years of research, there was a correlation between fruit weigh with fruit length and fruit weight with fruit diameter. Wheeler gave significantly higher b* (yellow) values in both years than any other cultivar. In year one Tean Ma had the highest positive a* (red) value, where in year two Wheeler had the highest a* value. Hart had significantly higher L* values in year two compared to all the other carambola cultivars. In year two Arkin had the lowest L* value to all the other cultivars except for B-10. Our data did not show one cultivar to consistently produce a higher BRIX reading when juxtaposed to the rest of the cultivars in the experiment. The use of carambola cultivars not used in this experiment may produce significantly different morphological and physicochemical readings than those recorded from this research.
