UPSC 2010: Mon 863 is a variety of maize. It was in the news for the following reason
(a)It is a genetically modified dwarf variety which is resistant to drought
(b)It is a genetically modified variety which is pest resistant
(c)It is a genetically modified variety with ten times higher protein content than regular maize crop
(d)It is a genetically modified variety used exclusively for bio-fuel production
Attempt This Question
Not attemptedCorrect Answer: (b) It is a genetically modified variety which is pest resistant
MON 863 is a Monsanto-developed transgenic maize line that expresses the Cry3Bb1 Bt-toxin, giving the plant resistance to corn-rootworm and other coleopteran pests; hence it was in the news as a pest-resistant GM variety. The other options describe traits (drought tolerance, high protein, bio-fuel use) that do not apply to MON 863.
