Ill ABSTRACT STUDY ON DISTRIBUTION, PATHOGENİCÎY AND MYCELIAL COMPATIBILITY GROUPS OF Sclerotinia sclerotiorum (LİB.) DE BARY, CAUSAL AGENT OF WHITE MOLD DISEASE OF GREENHOUSE GROWN CUCUMBER IN THE VİCİNİTY OF TOKAT AND AMASYA Abdurrahman ONARAN Gaziosmanpaşa Üniversitesi Graduate School of Natural Applied Science Deparment of Plant Protection Master Thesis 2005, 57 page Supervisor: Asist. Prof. Dr. Yusuf YANAR Jury: Prof. Dr. İzzet KADIOĞLU Jury: Prof. Dr. Erkol Demirci All Sclerotinia sclerotiorum isolates recovered from infected greenhouse grown cucumber in Tokat and Amasya provinces, in 2003-2004, were tested compatibility and assigned to a mycelial compatibility group (MCG). Five MCG's were identified among 235 isolates. From both localitions isolates pairs were designated compatible when no barrage zone was formed in the region of contact. They were designated incompatible when a clear zone and red line were formed in the region where the hyphae interact. MCG- 1, 2, 3, 4 and 5 consisted of 27, 20, 31, 58 and 12 isolates respectively remaining eighty seven isolates did not give any compatible reaction with each other and with one of five groups.IV Twenty three isolates representing 5 MCG's were evaluated for aggressiveness on cucumber seedlings usin a limited-term inoculation test. This test identified significant differecens in aggressiveness among isolates in different MCG's as well as in the same MCG.
