Correct option is C
What Are Transgenic Crops?
Transgenic crops are plants that have been
genetically modified by introducing
foreign DNA using biotechnology techniques.
The goal is to impart
novel traits like:
Insect resistance (e.g., Bt crops)
Herbicide tolerance
Delayed ripening
Improved nutritional content
�� First Transgenic Crop in History:
The
first successful transgenic plant was
tobacco, developed in
1983.
Scientists
inserted a gene for antibiotic resistance using
Agrobacterium tumefaciens-mediated transformation.
It demonstrated for the first time that
foreign DNA could be stably integrated into plant genomes and
expressed.
✅ Tobacco served as a
model plant due to its ease of transformation and regeneration in tissue culture.
�� Other Transgenic Crops (for reference):
Cotton (Bt cotton) – Commercialized in the 1990s for insect resistance.
Soybean – Widely grown transgenic crop for herbicide resistance.
Flax – Genetically modified later, not the first.
�� Explanation of Options:
(a) Cotton – ❌ One of the first commercial GM crops, but not the first developed.
(b) Soybean – ❌ Became common in the 1990s; not the first.
(c) Tobacco – ✅
Correct,
first transgenic crop developed in 1983.
(d) Flax – ❌ Modified later; not a pioneer in transgenic technology.
