 Mustard DMH-11

Why in news?

Genetic Engineering Appraisal Committee  has  cleared GM mustard for environmental release and use in farmers’ fields. However, the approval is contingent on a final nod from Environment Minister .


Specific case of Mustard

  • DMH-11 is a Genetically Modified (GM) mustard hybrid. Hybrids are normally obtained by crossing two genetically diverse plants from the same species . But  natural hybridisation isnt possible in mustard because its flowers contain both female (pistil) and male (stamen) reproductive organs. Hence GM is only way to make HYV in this case


  • India is importing 15 million tonnes of edible oils . Hence ,  there is need to raise domestic crop yields


Other justifications in allowing DMH-11

  • GM technology has already been commercialised in India through Bt cotton.  Since  Bt hybrids were first planted in 2002, there isn’t  any evidence to show that  Bt cotton is causing any adverse health effects.


  • Cotton seed oil from Bt Cotton is used and is perfectly safe.  Cotton-seed oil is the second largest produced edible oil in the country (1.4 million tonnes) after mustard (2 million tonnes).


  • Already importing GM Oil : Also India annually imports 3 million tonnes of soyabean oil which is predominantly GM.


  • The developer is a government-funded institution (Centre for Genetic Manipulation of Crop Plants at Delhi University), as opposed to Bt cotton intellectual property of multinational, namely Monsanto.


Against Points

  • DMH-11 employs a gene that will compel farmers to use specific herbicides & pesticide and be dependent on one or two companies (Bayer)  having monopoly over pesticide
