A new method for testing the resistance of cacao to witches' broom (Crinipellis perniciosa)



A new method for testing the resistance of cacao to witches' broom (Crinipellis perniciosa)



Revista Theobroma 10(4): 175-186



When basidiospores were tested with an ethanol extract from young shoots of the field resistant cacao clones SCA6 and SCA12, they failed to germinate and plasmolysis set in. Similarly prepared extracts from the highly susceptible clones ICS39 and UF677 promoted the development of short, swollen germination tubes.
