Question

The first transgenic crop approved for cultivation in USA during the year 1994 was:

• A. Mango
• B. Tomato
• C. Brinjal
• D. Okra

Hint:

"Flavr Savr" = Tomato (1994).
It is a classic milestone in agricultural biotechnology, representing the first commercial release of a genetically modified food crop.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Transgenic crops are genetically modified to introduce desirable traits such as pest resistance, herbicide tolerance, or improved shelf-life.

Step 2: Detailed Explanation:
The first commercially grown genetically engineered food crop approved for human consumption was the Flavr Savr tomato.
It was developed by Calgene and approved by the FDA in the USA in 1994.
This tomato was modified to delay ripening and softening by suppressing the polygalacturonase (PG) enzyme, which breaks down pectin in cell walls.

Step 3: Final Answer:
The first transgenic crop approved in 1994 was Tomato, which corresponds to option (B).
