Descripción:	Components of resistance that reduce the epidemic rate of rubber tree leaf blight, have been evaluated on colchicine-induced polyploids (CIP) Hevea clones and on their respective natural diploids after inoculation of virulente Microcyclus ulei isolates to the diploid clones. SomeCIP clones have presented high level of resistance in comparison with their susceptible diploid clones, whereas other CIP clones were susceptible. The polyploid plant inherent factors controlling the resistanceto M. ulei and the induced polyploid potential for rubber tree breeding aiming at resistance to leaf blight are discussed.
