Q1. Consider the following statements about biofortified crop varieties in India: 1. Biofortified maize hybrids may be enriched with lysine and tryptophan. 2. Some wheat biofortified varieties are enriched with protein and iron. 3. Pusa Mustard 32 is described as enriched with low erucic acid. 4. Biofortification necessarily introduces foreign-species DNA into every crop variety. Which of the statements given above are correct?
Explanation
Statement 1 is correct: ICAR describes maize hybrids enriched with lysine and tryptophan. Statement 2 is correct: the cited ICAR page mentions wheat varieties enriched with protein and iron. Statement 3 is correct: Pusa Mustard 32 is described with low erucic acid. Statement 4 is incorrect: the ICAR bulletin says nutritional quality has been improved using breeding methods, so biofortification is not necessarily transgenic.
