Ten varieties of Lathyrus sativus seeds were analysed for the neurotoxin (BOAA) and trypsin inhibitor (TI) content. The BOAA content varied from 0.142 to 0.680%. The values of trypsin inhibitor content were also uniform with the exception of two varieties whose values were comparatively low. When the seeds were exposed to insects all the varieties were affected, but the two varieties showing low trypsin inhibitor content also showed some protection against infestation. Variety P-24 was low in BOAA and trypsin inhibitor content with comparatively low insect susceptability.
