Abstract:\u00a0<\/strong><\/span><\/p>\n

Dry root rot of chickpeas, caused by the Rhizoctonia bataticola<\/em>, is one of the most significant challenges facing chickpea cultivation globally and in Syria. Despite the importance of this disease, due to its adaptation to drought conditions and its host range is widely, studies on it in chickpeas are almost nonexistent. Therefore, this research aimed to identify the factors and characteristics of the fungal structure that affecting on the virulence (pathogenicity) of the fungal community prevalent in Syria during 2024. Thirty-nine isolates, were isolated from samples have typical symptoms of the pathogenic. The pathogenicity of isolates was evaluated against ILC 482 susceptible variety, and the correlation between pathogenicity, microscopic and morphological characteristics of the isolates was investigated. These characteristics included growth rate, time of sclerotium formation, sclerotium structure and density, growth pattern and width mycelial, and the extent of Monilioid cells. The results showed significant variation among the isolates; the isolates prevalent in Syria were distributed into four groups based on growth rate, with 13% exhibiting rapid growth. The mycelium width ranged from 3.8 to 6.3 micrometers. 54% of the studied isolates exhibited Monilioid cells formation, and regarding sclerotia, 51% of the isolates had a coarse-granular structure. The dominant fungal community in Syria during 2024 was characterized by high virulence, with 51% of the studied isolates exhibiting high virulence. By comparing all studied cultural, microscopic, and morphological characteristics of the fungal isolates with their pathogenicity, results showed that virulence of isolate was significantly correlated with mycelium type (aerobic growth), the presence of Monilioid cells, and sclerotia density, with correlation coefficients of 0.76, 0.87, and 0.69, respectively.<\/span><\/p>\n
