Abstract: As regards screening studies, the different groups of forty germplasms of pigeonpea were screened for their resistance to pod borers. out of these, four germplasms viz., PT-0555-2-2, PT-01-11-2, PKV TARA and BDN-2001-6 were found to be most promising genotypes against H. armigera, E. atomosa and M. obtusa by recording the less pod damage in the range of 4.22 – 4.83, 1.55- 2.42 and 2.90- 4.02 per cent as compared to state check Vipula (7.57, 3.23, 5.72 %, respectively). As regards the morphological characters, it was observed that the growth habit and colour of flower and pod did not influence the pod borer infestation. Whereas on the basis of pod size, long podded varieties were more damaging to H. armigera and E. atomosa. Irrespective of morphological characters, the biochemical content of total phenol was negatively significant correlated with pod damage caused by E. atomosa and negatively non-significant correlated with H. armigera and M. obtusa, whereas, reducing sugar was positively significant correlated with all pod borers. While non-reducing sugar positively significant correlated with E. atomosa and positively non-significant with H. armigera and M. obtusa.
