Şeker Pancarlarından Elde Edilen Rhizoctonia spp. İzolatlarının Hif Birleşme Reaksiyonları ve Klasik Yollarla Anastomosis Grup Temini

Abstract

Root rots were detected in 691 of 866 fields from Konya beet sugar beet growing areas between 2015 and 2017 and among these fungi most Rhizoctonia spp. has been identified. In the diagnosis of fungus; morphological diagnostics, isolation, microscopic observation, determinations of anastomosis groups by classical means were used, were used for the definitive diagnosis. 61 isolates of 71 isolates were identified as multinucleate and 10 isolates were identified as binucleate Rhizoctonia spp. In determining anastomosis group with classical method; the isolates are divided into groups, according to hyphal reactions of Rhizoctonia isolates with test isolates; isolates were divided into groups according to C0, C1, C2, C3 type reactions and according to the way the hyphae are directed towards each other. This study is important for leading the studies to be carried out on this subject in terms of visual and methodical detail of anastomosis group determination steps and hyphal fusion in the classical way.
