Present investigation includes anatomical study of wild rice accessions at internodes position were carried out to understand the relationship between plant anatomy and resistance against Brown plant hopper. This study includes thickness of epidermis and distance between epidermis and vascular bundle and the corresponding evaluation of accessions through seed box technique. Maximum thickness of epidermis was observed in PTB 33 (15.89 µm) followed by O. nivara D: 13 (15.67 µm) and O. nivara VS: 83 (14.05 µm). Maximum distance was observed in PTB 33 followed by O. nivara VS: 54 and O. nivara VSR: 54. Minimum distance was observed in TN1, followed by O. nivara MS: 7 and O. nivara VSR: 76. Minimum average plant damage score by BPH through standard seed box technique tested against BPH was observed in Twenty two rice accessions were categorized as highly resistant (HR).
