One of the constraints to commercial breadfruit production in the Caribbean is the very limited genetic diversity of this introduced species. During the 1990s, 'Ma'afala', a common breadfruit cultivar in the Pacific, was introduced to Trinidad and Tobago by the University of the West Indies (UWI) and the former Ministry of Agriculture, Lands and Fisheries. 'Ma'afala' has been propagated and sold to homeowners and farmers by the Ministry. At the UWI, this cultivar has been evaluated for horticultural characteristics important to commercial production including propagation, tree height, time to bearing, seasonality, yield, fruit traits and susceptibility to disease. For purposes of utilisation, the nutrient composition and its suitability for flour production have also been evaluated. Information on on-farm performance was obtained through interviews with farmers. The results suggest that for commercial orchards, 'Ma'afala' compares favourably with the local cultivars, 'Yellow' and 'White', in terms of tree form and that it may extend the season of breadfruit availability. However, its susceptibility to tree decline and death, and certain fruit characteristics which are undesirable for processing and consumer acceptance in certain markets, can significantly limit its potential for commercial use in Trinidad and Tobago. However, the advantages offered by 'Ma'afala' justify additional research to address its limitations. This evaluation emphasises the importance of comprehensive cultivar evaluation before release for commercial production.
