With reference to the Genetically Modified mustard (GM mustard) developed in India, consider the following statements: 1) GM mustard has the genes of a soil bacterium that give the plant the property of pest-resistance to a wide variety of pests. 2) GM mustard has the genes that allow the plant cross-pollination and hybridization. 3) GM mustard has been developed jointly by the IARI and Punjab Agricultural University. Which of the statements given above is/are correct?

Question

Correct Answer: 2 only. DMH-11 is a Genetically Modified (GM) mustard hybrid. It is herbicide tolerant mustard. DMH -11 contains three genes viz. Bar gene, Barnase and Barstar sourced from soil bacterium. It was created by using &ldquo;barnase/barstar&rdquo; technology for genetic modification by adding genes from soil bacterium that makes mustard self-pollinating plant. Hybrids are normally obtained by crossing 2 genetically diverse plants from the same species. The 1st-generation offspring resulting from it has higher yields than what either of the parents is individually capable of giving. But there is no natural hybridization system in mustard, unlike in, say, cotton, maize or tomato. This is because its owners contain both the female (pistil) and male (stamen) reproductive organs, making the plant naturally self-pollinating. A team of scientists at Delhi University led by former vice-chancellor Deepak Pental has bred DMH-11 (Dhara Mustard Hybrid)
