Application of embryo culture is in

Options

A. Clonal propagation
B. Overcoming hybridisation barrier
C. Production of alkaloids
D. Formation of somaclonal variations.

Answer

### Step-by-Step Solution:

1. **Understanding Embryo Culture**:
- Embryo culture is a technique used in plant biotechnology where embryos are extracted from seeds and cultured in a nutrient medium. This allows for the development of embryos that might not survive in their natural environment.

2. **Identifying Applications**:
- The question asks for the applications of embryo culture. We need to evaluate the options provided:
a. Clonal Propagation
b. Overcoming Hybridization Barrier
c. Production of Alkaloids
d. Formation of Somaclonal Variations

3. **Evaluating Each Option**:
- **Clonal Propagation**: This involves producing genetically identical plants from a single parent plant. Embryo culture can be used to propagate plants that are difficult to grow from seeds.
- **Overcoming Hybridization Barrier**: Embryo culture can help in cases where hybrid seeds fail to develop properly, allowing for the growth of hybrid plants.
- **Production of Alkaloids**: This is not a direct application of embryo culture; it relates more to the extraction of compounds from plants.
- **Formation of Somaclonal Variations**: This refers to genetic variations that occur in plants regenerated from tissue culture, which is not the primary application of embryo culture.

4. **Conclusion**:
- Among the options, the most relevant application of embryo culture is **Clonal Propagation**. This technique allows for the efficient production of genetically identical plants, making it a valuable tool in agriculture and horticulture.

5. **Final Answer**:
- The answer to the question is **option a: Clonal Propagation**.
