For production of haploids, we culture

Options

A. Shoot tip
B. Anther
C. Root tip
D. None of these

Explanation

To solve the question regarding the production of haploids, we will follow these steps:

### Step 1: Understand the Concept of Haploids
Haploids are cells that contain only one set of chromosomes (n). They are important in plant breeding and genetic studies because they can be used to produce pure lines.

**Hint:** Recall that haploids are crucial for genetic studies and can be produced from specific plant tissues.

### Step 2: Identify the Plant Tissue Used for Haploid Production
In plant tissue culture, different parts of a plant can be cultured to produce haploids. The question provides options: shoot tip, anther, root tip, and none of these.

**Hint:** Think about which part of the plant is commonly used in tissue culture to produce haploids.

### Step 3: Focus on Anther Culture
Anther culture is a technique where the anther (the part of the stamen that contains pollen) is cultured on a suitable medium. When cultured, the anther can develop into haploid embryoids.

**Hint:** Remember that anthers contain pollen grains, which can be induced to form haploids when cultured.

### Step 4: Conclude the Answer
Based on the understanding that anther culture leads to the production of haploids, we can conclude that the correct answer to the question is to culture the anther.

**Final Answer:** The correct answer is **B) Anther**.
