Context

• Three States, Gujarat, Maharashtra and Telangana, have deferred a proposal, approved by the Centre’s Genetic Engineering Appraisal Committee (GEAC), to test a new kind of transgenic cotton seed that contains a gene, Cry2Ai, that purportedly makes cotton resistant to pink bollworm, a major pest. 
• The conflict shows that a broad acceptance of genetically modified crops continues to be elusive.

What is the status of transgenic crops in India?

• There is an array of crops — brinjal, tomato, maize, chickpea — in various stages of trials that employ transgenic technology. However, cotton remains the only transgenic crop that is being commercially cultivated in India. 
• After a long hiatus, the GEAC, the apex technical body charged with evaluating proposals for testing genetically modified (GM) seeds, approved the environmental release of Mustard hybrid DMH-11 and its parental lines, in 2022 for seed production and testing. This is one step away from full commercial cultivation.
• However, the GEAC, which is under the Union Environment Ministry, isn’t the final arbiter in the case of GM crops. 
• There is long-standing litigation in the Supreme Court on the permissibility of allowing transgenic food crops in farmer fields. Following the GEAC approval for DMH-11, the petitioners approached the Supreme Court asking for a stay on the release of the crop because it would encourage farmers to spray herbicides, which are banned in India. 
• Hearings on this case are still ongoing. In 2017, the GEAC had accorded clearance for GM mustard but went back on its decision and imposed additional tests. In 2010, the GEAC had approved GM Brinjal, but this was put on an “indefinite moratorium” by the government.

What is the process of regulating transgenic crops in India?

• The process of developing transgenic crops is an elaborate one as inserting transgenic genes into plants to elicit a sustained, protective response is a mix of both science and chance. There are multiple safety assessments done by committees before they are cleared for further tests in open plots of land which are located at either agricultural universities or plots controlled by the Indian Council for Agricultural Research (ICAR). 
• A transgenic plant can apply for commercial clearance, only after it has proven to be demonstrably better than comparable non-GM variants on claimed parameters (for instance, drought tolerance or insect resistance) without posing ecological harm to other species that may be being cultivated in the vicinity. 
• Open field trials often take place over multiple crop seasons and types of geographical conditions, to assess its suitability across different States.

Why have Gujarat, Maharashtra and Telangana rebuffed the GEAC?

• The cotton seed has been developed by the Hyderabad-based Bioseed Research India with Cry2Ai which makes it resistant to pink bollworm. The first generations of transgenic cotton had been developed to inure cotton against a more widespread pest called the American bollworm. 
• The Cry2Ai seed has passed preliminary, confined trials and was recommended by the GEAC to be tested in farmer’s fields at Telangana, Maharashtra, Gujarat and Haryana. 
• Agriculture being a State subject means that, in most cases, companies interested in testing their seeds need approvals from the States for conducting such tests. Only Haryana gave permission for such tests.
