Androgenic haploids are produced in anther cultures by

Options

A. tapetum
B. anther wall
C. connectives
D. yong pollen grains

Answer

**Step-by-Step Solution:**

1. **Understanding Androgenic Haploids**:
- Androgenic haploids refer to haploid plants that are produced from male gametes. In this context, the male gamete is the pollen grain.

2. **Anther Culture Technique**:
- Anther culture is a plant tissue culture technique where the anthers (the part of the stamen that contains pollen) are cultured in a suitable medium to induce the development of haploid plants.

3. **Role of Pollen Grain**:
- The process involves culturing the pollen grains found within the anthers. When these pollen grains are cultured, they can develop into haploid plants, known as androgenic haploids.

4. **Evaluating Options**:
- The question provides several options to identify the correct answer regarding what produces androgenic haploids in anther cultures:
- **Tapetum**: A layer of nutritive cells that supports pollen development but does not directly produce haploids.
- **Anther Wall**: The outer layer of the anther that protects the pollen but does not produce haploids.
- **Connective**: The tissue that connects the anther to the filament, not involved in haploid production.
- **Pollen Grain**: The correct answer, as it is the male gamete that, when cultured, leads to the formation of androgenic haploids.

5. **Conclusion**:
- The correct answer is "Pollen Grain" as it is the component responsible for producing androgenic haploids in anther cultures.

**Final Answer**: Androgenic haploids are produced in anther cultures by **pollen grain**.
