Item Performance of F1 Hybrid Coconuts in Jamaica(1974) Harries, H.C.Dwarf X tall, tall X dwarf and tall X tall F, hybrid coconuts in Jamaica have characteristics that are intermediate between those of their parents. Each parent is deficient in at least one of the characteristics considered (disease resistance, precocity, leaf production, bunch production, palm size, nut number, nut weight and copra production) so that the overall performance of the F, hybrid is better than that of either parent. Only when considering lethal yellowing disease does the intermediate level of resistance constitute a barrier to the widest use of hybrids.
