A technique of micropropagation is

Options

A. Protoplast fusion
B. Embryo rescue
C. Somatic hybridization
D. Somatic embryogenesis

Explanation

**Step-by-Step Solution:**

1. **Understanding Micropropagation**: Micropropagation is a technique used in plant tissue culture to produce a large number of plants from a small amount of plant material. It involves growing plant cells, tissues, or organs in a controlled environment on a nutrient medium.

2. **Identifying Techniques Related to Micropropagation**: Several techniques are associated with micropropagation, including:
- Protoplast fusion
- Embryo rescue
- Somatic hybridization
- Somatic embryogenesis

3. **Explaining Each Technique**:
- **Protoplast Fusion**: This technique involves the fusion of protoplasts (plant cells without cell walls) from different species to create hybrid cells.
- **Embryo Rescue**: This technique helps in the survival of embryos that might not develop properly in the parent plant. It involves transferring embryos to a nutrient medium to grow into plants.
- **Somatic Hybridization**: This technique involves the fusion of somatic cells from two different plants to create hybrid plants.
- **Somatic Embryogenesis**: This is a specific method of micropropagation where somatic cells are induced to form embryos, which can then develop into whole plants.

4. **Identifying the Correct Technique**: Among the options provided, somatic embryogenesis is the most closely related to micropropagation as it directly involves the generation of embryos from somatic cells, leading to the production of new plants.

5. **Conclusion**: Therefore, the correct answer to the question "A technique of micropropagation is" is **Somatic Embryogenesis**.
