Abstract
Objective: The objective of the present study was to evaluate the response of 10 chickpea genotypes from INIFAP to the damage caused by the fungal complex.
Design/methodology/approach: Seedlings (15-day-old) of 10 genotypes (Blanco Sinaloa '92, Blanoro, Combo 743, CUGA2054, HOGA067, CUGA3168, CUGA08-1210, CUGA09-3160, R-12-1509 and R-12-1507) were inoculated by immersion of roots in a suspension of mycelial fragments of two isolates (high and low virulence) of each of the fungi Fusarium languescens, M. phaseolina, S. rolfsii and S. sclerotiorum. Disease severity evaluation was performed 30 days after inoculation. The entire experiment was performed twice.
Results: The genotypes showed greater susceptibility to S. sclerotiorum and S. rolfsiicompared to F. languescens and M. phaseolina. The highly virulent isolates caused a significant difference in the severity of the disease in the genotypes evaluated.
Findings/conclusions: All chickpea genotypes showed susceptibility to the fungal complex that causes wilt.
