GEAC’s nod for environmental release of GM Mustard

In News 
  • Genetic Engineering Appraisal Committee (GEAC) has approved the “environmental release” of indigenously developed genetically modified (GM) Mustard Seeds.
Dhara Mustard Hybrid (DMH-11)
  • Dhara Mustard Hybrid- 11( DMH- 11), was developed by Deepak Pental of Delhi University, through transgenic technology, in 2002. DMH – 11 was created through transgenic technology, primarily involving the Bar, Barnase and Barstar gene systems.
  • DMH-11 by crossing a popular Indian mustard variety ‘Varuna’ (the barnase line) with an East European ‘Early Heera-2’ mutant (barstar).
  • DMH-11 is claimed to have shown an average 28% yield increase over Varuna in contained field trials carried out by the Indian Council of Agricultural Research (ICAR).
GM Crops
  • GM foods are derived from plants whose genes are artificially modified, usually by inserting genetic material from another organism, in order to give it a new property, such as increased yield, tolerance to a herbicide, resistance to disease or drought, or to improve its nutritional value.
  • Probably the best known variety of GM rice is golden rice.
  • Golden rice involves the insertion of genes from a plant -- both daffodils and maize have been used -- and a soil bacterium to create a grain that is enriched with Vitamin A.
  • India has approved commercial cultivation of only one GM crop, Bt cotton.
  • No GM food crop has ever been approved for commercial cultivation in the country.
