Tissue culture is beneficial for :

Options

A. Micropropagation
B. Production of disease free plants
C. Androgenic haploid
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Tissue Culture**:
- Tissue culture is a collection of techniques used to grow plant cells, tissues, or organs under sterile conditions on a nutrient culture medium with a known composition.

2. **Micropropagation**:
- One of the primary benefits of tissue culture is micropropagation. This method allows for the rapid production of multiple clones of a plant, which are genetically identical to the parent plant.

3. **Production of Disease-Free Plants**:
- Tissue culture is also beneficial for producing disease-free plants. Since the process is conducted in a sterile environment, it minimizes the risk of contamination and helps in generating healthy plants.

4. **Androgenesis and Creation of Haploids**:
- Tissue culture techniques can be used to create haploids through a process called androgenesis. Haploids are important for breeding programs as they can be used to develop pure lines.

5. **Conclusion**:
- Given the benefits outlined, tissue culture is beneficial for micropropagation, production of disease-free plants, and the creation of androgenic haploids. Therefore, the correct answer is "all the above".

**Final Answer**: All the above.
