The most widely recognised breadfruit cultivars in the Caribbean are the 'Yellow' and the 'White'. However, yield data are not available for these cultivars or for those that are less known. Fouryear old trees of 12 cultivars, five from Jamaica, five from St. Vincent and two from Trinidad and Tobago growing in a germplasm collection at the University Field Station of the University of the West Indies in Trinidad, were evaluated. The results indicated that the cultivars differed in their time of bearing, yield, fruit number and fruit size. 'Yellow' was earlier, less seasonal and higher yielding than most of the other cultivars during early growth.
