Macrophomina phaseolina (Tassi) Goid. is a fungal pathogen causes significant economic losses, including root and hypocotyl rot, root collar and stem blight, which are common in bean production areas. In this study, 24 bean genotype developed by the Black Sea Agricultural Research Institute and M. phaseolina isolate M1 isolated from bean cultivation areas were used.
This research was carried out with pot experiments in climatic chamber conditions to determine the reactions of some bean (Phaseolus vulgaris L.) genotypes against M. phaseolina, which causes charcoal rot disease in beans. Among the bean genotypes evaluated within the scope of the study, KMF-11-30 and ARSLAN genotypes were found to be tolerant, while the 20-BBarBVD-10 genotype was found to be resistant.
