Abstract
Two races of Corynespora cassiicola have been found to affect immature and mature leaves of Hevea brasiliensis in Malaysia. Immature and mature leaves of 20 randomly selected progenies from family PB 5/51 X IAN 873 were used to screen resistance/susceptibility to isolates CSB 16 (race 1) and CLN 16 (race 2) separately. Analysis of Variance (ANOVA) and the Least Significant Difference (LSD) test at a 0.05 probability level were used to compare treatment means. The multifactor ANOVA was used to analyse the results which include main effects and interactions between factors studied viz. progenies leaf types and isolates. Immature leaves were more susceptible to both races than mature leaves and isolate CLN 16 (race 2) was the more virulent to this Hevea family. This study was able to detect five progenies that were resistant to both fungal isolates. They were progenies 1636 1747 3223 3320 and 3562.
