- Sophiyani “ Uji Resistensi Beberapa Genotipe Plasma Nutfah Karet (Hevea brasiliensis Muell. Arg.) Terhadap penyakit Gugur Daun (Corynespora cassiicola (Berk. & Curt.) Wei.) Di laboratorium “ with the conselling Mr. Ir. Lahmuddin Lubis, MP. As a leader, Mr. Kasmal Arifin, MSi as co-author and Ir. Aidi Daslin Sagala, MS. The research was conducted at Sungei Putih Rubber Research Center since Agustus to Oktober 2009. The aims of the research was to found rubber genotype whose resistant from fall off leaf diseases (C. cassiicola). This research used the method of complete non factorial random design with 30 combine of treatments and 3 repeats. Genotype of plasma nutfah from hevea that used was PB 217, PB 254, PB 312, PB 314, PB 330, PB 340, PB 350, PB 359, PB366, IRR 5, IRR 7, IRR 12, IRR 104, IRR 105, IRR 107, IRR 112, IRR 118, IRR 119, IRR 136, RRIM 901, RRIM 908, RRIM 911, RRIM 921, RRIM 937, RRIC 100, RRIC 102, RRIC 110, RRII 105, RRII 176 dan PB 260 as equal. The result of research showed that the PB 217 (P2), PB 340 (P7), PB 359 (P9), IRR 5 (P11), IRR 107 (P16), IRR 112 (P17), RRIM 901 (P21), RRII 105 (P29), RRII 176 (P30), PB 314 (P5), IRR 7 (P12), IRR 104 (P14), RRIM 921 (P24) were high susceptible, PB 350 (P8), PB 366 (P10), IRR 12 (P13), IRR 136 (P20), RRIM 911 (P23) were susceptible, PB 254 (P3), P312 (P4), PB 330 (P6), IRR 105 (P15), RRIM 901 (P21), RRIM 937 (P25), RRIC 100 (P26), RRIC 102 (P27), RRIC (P28) moderat, dan PB 260 (P1), IRR 118 (P18), IRR 119 (P19) was high resistant. The size of conidia, long size is 50-113μm and thin size is 8-18 μm and have many part there are 4-13 part at conidia.
