摘要

Chickpea is a valuable crop with high nutritional value. It also helps maintain soil fertility, especially in dry and semi-arid areas such as Iran, where it is cultivated in crop rotation with cereals. Wilt and root rot is a devastating disease commonly occurring during all growing seasons in Iran and inflicts significant yield losses on farmers. In all previous studies, Fusarium oxysporum f. sp. ciceris has been reported as the leading cause of the disease in Iran. However, in most previous studies, identification of the pathogen was based exclusively on morphological characteristics, and isolates of F. oxysporum species complex (FOSC) were considered as the forma specialis of F. oxysporum f. sp. ciceris, simply because of their association with wilt-like symptoms. In a recent study, FOSC was still the predominant pathogenic Fusarium species on chickpea in Iran. However, most affected plants showed no discoloration in the vascular tissues. In this study, out of more than 200 FOSC isolates obtained from symptomatic plants, the pathogenicity of 49 isolates was investigated. Among the pathogenic isolates (47 isolates) that were identified using a combination of species-specific primers and TEF-1α gene sequencing, about 85% were F. redolens and only about 10% were F. oxysporum f. sp. ciceris, these results show that F. redolens is the most prevalent soil-born pathogen that causes yellowing and wilting of chickpea in western Iran. This species has been reported in many chickpea-producing countries; however, the predominance of this pathogen has not been reported.
