- The research was conducted in Laboratory Plant Protection Sungei Putih Rubber Research Center since August 2007 to October 2007. The aims of the research was to know level of resitance of rubber IRR 200 clones to fall of leaf C. gloeoesporioides disease. The research used the desigen Complete Random Device (CRD) non factorial with 25 treatmens (21 clones treatment of IRR 200 series and 4 control clone) and 3 mutliplication. The rubber IRR 200 series were used is IRR 250, IRR 253, IRR 255, IRR 256, IRR 259, IRR 262, IRR 263, IRR 264, IRR 266, IRR 267, IRR 268, IRR 270, IRR 271, IRR 272, IRR 276, IRR 277, IRR 278, IRR 284, IRR 285, IRR 292, IRR 293 and RRIC 100, BPM 24, PB 217 and PB260 is control clones. The result of research Mean showed that the IRR 200 series and 4 control clones were resistence which do not varieted to C. gloeoesporioides. Clones PB 260, PB 217, BPM 24 and IRR 277 was moderate. Clones RRIC 100, IRR 255, IRR 259, IRR 262, IRR 263, IRR 270, IRR 278, IRR 293, IRR 256, IRR 264, IRR 267, IRR 268, IRR 271, IRR 272, IRR 284 and IRR 285 was rather suspectible. Clones IRR 250, IRR 253, IRR 266, IRR 276 and IRR 292 was suspectible.
