The Inter-Academy Report on GM crops submitted in September, 2010, elicited a great deal of public discussion, although it was meant only for limited circulation. In retrospect, this was to be expected in view of the nature of the issue. The report has now been updated. The updating involved the rectification of the slip which has been acknowledged and the consequent rewriting of the section containing the narrative on Bt brinjal. That does not materially affect the main conclusions and recommendations. The literature on GM crops is voluminous. More than a hundred appropriate references have been included in the updated report. In other respects, the body of the report remains substantially the same.
