What is the major advantage of producing plants by micropropagation ?

Explanation

**Step-by-Step Solution:**

1. **Definition of Micropropagation**: Micropropagation is a technique used to produce new plants from plant tissues in a controlled environment, typically using a culture medium.

2. **Production of Large Numbers**: One of the major advantages of micropropagation is that it allows for the rapid production of a large number of plants in a short period of time. This is particularly beneficial for commercial agriculture and horticulture.

3. **Genetic Uniformity**: The plants produced through micropropagation are genetically identical to the parent plant. This ensures that desirable traits are preserved in the new plants, which is crucial for maintaining quality in crops.
