Conteúdo: This study investigated lesion sizes, latent periods and sporulation of leaf discs as indicators of resistance of Hevea to Microcyclus ulei. There were clonal differences in the rate of development of mycelium and appearance of lesions, sizes of lesions, latent period and the quantity of conidia produced on discs of Hevea leaves. There was a positive correlation between conidial production and lesion size, and negative correlations existed between conidial production and latent period and lesion size and latent period. Latent period and sporulation are also important components for assessment of resistance. Clones GT 711, RRIM 501, CNS AM 7701, SIAL 842 and SIAL 263 possessed relatively smaller lesions, longer latent periods and reduced sporulation. On these clones, the differences in lesion size were significant between clonesbut not between races of Microcyclus ulei. However, diffences in conidial production between clones, races and the interaction between clones and races were significant.
