An experiment was conducted to measure the change in the concentration of biochemical compounds viz., total phenol, flavanol and ortho-dihydric phenol and cell permeability parameter viz. electrolyte leakage in resistant (H00-256, HC-3) and susceptible (HC-1, HC-5& L-550) chickpea genotypes at six different intervals viz. 0, 2, 4, 6, 8 and 10 days of inoculation. The total phenols, flavenols and orthodihydric phenols were higher in resistant compared to susceptible genotypes at all the comparable intervals. The concentrations of total phenols and flavenol showed an increase between two to four days of inoculation, while ortho-dihydric phenol increased up to sixth day followed by decline. The cell membrane permeability increased continuously after inoculation at all the intervalsbut the electrolyte leakageswere higher in susceptible genotypes.
