Safety Regulation for Transgenic Plants - The main concerns while taking transgenic plants to the field relate to the possibilities of
(i) their becoming persistent weeds,
(ii) gene transfers from them to other plants making the latter more persistent or invasive, and
(iii) their being detrimental to the environment.

In general, testing of transgenic plants should progress in a stepwise manner from laboratory to growth chamber, to greenhouse, to limited field testing, to large scale field testing.

Many countries have developed their own procedures and policies regulating field tests of such plants. In India, DBT, New Delhi, is concerned with the regulation of field testing of transgenic plants.
