Question

The in vitro 'slow growth culture' is a method used for

• A. Genetic transformation
• B. Conservation of plant genetic resources
• C. Induction of somaclonal variation
• D. Elimination of latent contamination

Hint:

Slow growth culture:
- For medium-term conservation.
- Conditions: Low temperature, reduced nutrients.
- Used for germplasm storage in vitro.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
This question tests knowledge of in vitro conservation techniques.

Step 2: Detailed Explanation:
Slow growth culture is a method used for conservation of plant genetic resources.
It involves growing plant material under conditions that slow growth (low temperature, reduced nutrients).
This allows long-term maintenance of germplasm without frequent subculturing.
Genetic transformation (A): Uses different methods (Agrobacterium, biolistics).
Somaclonal variation (C): Variation induced by tissue culture.
Elimination of latent contamination (D): Use of antibiotics or heat treatment.
Thus, slow growth culture is used for conservation.

Step 3: Final Answer:
Thus, slow growth culture is used for conservation of plant genetic resources, which corresponds to option (B).
