Abstract

Experiments on chickpea genotypes and varieties (CPC-814, CPC-830, CPM-825, CPM-860, BARIsola-3 and Binasola-4) were conducted at two locations (Magura and Nachole) of Bangladesh under pesticide free open field conditions to screen out against pod borer on the basis of physical parameters. The mean pod damage among the test entries ranged from 8.3-15.2% in Magura and 13.9-16.6% in Nachole. The physical characteristics i.e. number of branches plant-1 , number of leaves branch-1, number of pods plant-1, number of infested pods plant-1, hundred seed weight (g), grain yield (t ha-1), trichomes density cm-2 area of pod shell were recorded and analyzed. A significant positive relationship of pod borer infestation with the number of branches plant-1 and negative relationships were observed with
