Effect of Total Protein Content on Pod Damage by Pod Borers in Field Bean

A study was undertaken to understand the changes in biochemical constituents like total protein content in twotolerant entries (MAC 3 and LMA) and two susceptible groups (DB and HA 3) of field bean against pod borers namely H. armigera and A. atkinsoni. The total protein content was lower in the tolerant group than in the susceptible entries. MAC 3 recorded the lowest (18.1, 21.2 and 23.7%), while HA 3 recorded the highest protein content (20.3, 23.1 & 26.5%) in leaves. podsand seeds, respectively. The mean total protein content was 19.33, 22.08 and 25.05 per cent in leaves, pods and seeds, respectively.
