The morphological characters viz., pod length, pod width, pod wall thickness and trichome density in selected genotypes were studied and the correlation studies revealed that pod length showed positive correlation (r = 0.90) with pod damage. However, pod width showed non-significant association (r = 0.34) with the pod damage. While, pod trichome density and pod wall thickness (r = -0.89 & -0.88, respectively) showed significant negative association with pod damage. The biochemical basis of resistance to pod borers in field bean genotypes revealed, the total phenols in pods of healthy and infested samples (r= - 0.92 & -0.95, respectively) showed a significant and negative relationship with per cent pod damage caused by pod borers. While, total sugars in healthy and infested pods (r = 091 & 0.94, respectively), reducing sugars in healthy and infested pods (r = 0.89 & 0.92, respectively), crude proteins in healthy and infested pods (r = 0.90 & 0.96, respectively) and amino acids in healthy and infested pods (r= 0.96 & 0.91, respectively) showed a significant positive association with per cent pod damage caused by pod borers.
