Experiments PB-GC 3 and PB-GC-5, planted on the Marc Delorme Coconut Research Station (Ivory Coast), compared hybrids between Dwarf x Tall and Tall x Tall coconut ecotypes, respectively. These trials confirmed or revealed the high yield potential of some crosses, e.g., MYD x WAT (PB 121), MRD x PYT (PB 132) and WAT x RLT (PB 213). The factorial design of crosses in these experiments (NC II type) enabled a genetic analysis of characters to be made. In GC 5, the effect due to Dwarfs was generally greater than that due to Talls, because of major differences between Malayan Red and Yellow Malayan, and between Solomon and Rennell Talls. Heritability estimates were high for copra to nut and for oil weight per nut (correlated with copra), fairly high for number of nuts per tree, medium for bunch number and very low to nil for copra yield per tree. Estimates for Dwarf and for Talls were in good agreement.
