Commercial cultivation of broccoli (Brassica oleracea cv. italica Plenck) is not widely practiced in the Eastern Caribbean in spite of a modest but steady demand which is satisfied by imports. Development of heat-tolerant commercial varieties in recent years has encouraged some ad hoc attempts at commercial production based on individual farmer experience and seed catalogue ratings especially in relation to varietal adaptability. Evaluation of nine currently available commercial varieties, and field observations on the performance of a few others, have indicated good levels of adaptability of most varieties for year round production, and the ability of most varieties to head satisfactorily in the cool season. Yields of over lO,OOO kg ha-l were recorded for most varieties, but three entries-- Early Value, Southern Comet and GreenTop--were outstanding for yield and head size. Green Comet, the standard variety, also produced well and rated highest for head uniformity. Earlier maturing varieties seem to have an advantage under the erratic environmental conditions of the region.
