Options

A. Brassica
B. Datura
C. Nicotiana
D. Gossypium

Answer

To answer the question "Haploids from anther were first obtained from," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Haploids**:
- Haploids are organisms or cells that have a single set of chromosomes. They are important in plant breeding and genetic studies.

2. **Identifying the Method Used**:
- The method used to obtain haploids from anthers is known as **anther culture**. This technique involves using the anther as an explant in tissue culture to produce haploid plantlets.

3. **Historical Context**:
- The first successful anther culture was conducted in **1964** by scientists **Guha and Maheshwari**. They were pioneers in this field and their work laid the foundation for further research in haploid plant production.

4. **Identifying the Plant Used**:
- The specific plant from which haploids were first obtained through anther culture is **Datura inoxia**. This plant was used in their experiments, yielding a high number of plantlets.

5. **Evaluating the Options**:
- The options provided are:
- A) Brassica
- B) Datura
- C) Nicotina
- D) Gossypium
- Based on historical data, the correct answer is **B) Datura**, as it was the first plant from which haploids were successfully derived using anther culture.

### Final Answer:
The correct answer is **Datura**.
