The 1939 hand-pollinated seedling families were examined on April 14, 15, 22, 27 and 28, 1943, to determine their resistance to South American Leaf Disease. These crosses were made at Fordlandia estate and brought to Belterra where they were planted in plots C and D of block 91 at a regular field spacing.

On April 6-7, 1945, the 1364 seedlings from the 1938 crosses made at the Fordlandia estate of the Ford rubber plantations, were examined individually to determine their resistance to South American Leaf Disease (Dothidella ulei), and Black Crust (Catacauma Huberi). These seedlings are planted in Block 91, plot A, at Belterra estate at a regular field spacing.
