Androgenic haploids were produced from anther culture for the first time by

Options

A. Bateson
B. Ninan
C. Auerbach and stadler
D. Gucha and maheswari

Answer

**Step-by-Step Solution:**

1. **Understanding Androgenic Haploids**:
- Androgenic haploids are plantlets derived from the process known as androgenesis. This process involves the culture of anthers, which are the male reproductive parts of flowers that contain haploid microspore cells (pollen grains).

2. **Identifying the Process**:
- The production of androgenic haploids occurs through anther culture. In this technique, the anthers are cultured in a nutrient medium that promotes the development of haploid cells into plantlets.

3. **Historical Context**:
- The first successful production of androgenic haploids from anther culture was reported by two scientists, Guha and Maheshwari, in 1964. They conducted their research on the plant Datura inoxia.

4. **Research Findings**:
- Guha and Maheshwari discovered that when anthers were cultured in a nutrient medium containing coconut milk, numerous embryos were formed, which eventually developed into plantlets.

5. **Evaluating the Options**:
- The options provided in the question include Bateson, Neenan, Orbeck and Stadler, and Guha and Maheshwari.
- Bateson and Neenan were not involved in this specific research on androgenic haploids. Orbeck and Stadler are known for their work on mutations, not androgenic haploids.
- Therefore, the correct answer is Guha and Maheshwari.

**Final Answer**: Guha and Maheshwari.
