description: Ten promising short duration genotypes of pigeonpea were screened under field  conditions for two years (2013-15) to identify sources of resistance against pod borers. On  the basis of per cent pod damage and Pest Susceptibility Rating (PSR) index, genotypes  PUSA-2012-1, PA 409, PA 406, AL1747 were found to be least susceptible (PSR= 4 to 5)  while two genotypes, AL 1790 and AL 1770 were ascertained highly susceptible against  pod borers having damage rating of 8 over the susceptible check cultivar (Manak). Phenol  and flavonoid content present in the pod wall of all the test genotypes/cultivars were also  estimated. Highest phenol and flavonoid content was recorded from PUSA-2012-1 while  the lowest content was obtained from the genotype AL 1790. Correlation studies made  with these biochemical constituents revealed a significant and negative association of  pod damage (%) with phenol (r = -0.896**) and flavonoid (r = -0.872**) content in pod  walls. Thus the genotypes having higher content of phenols and flavonoids in their pod  walls offered resistance against pod borer complex.
