Which of the following is incorrectly matched

Options

A. Explant - Excised plant part used for callus formation
B. Cytokinins - Root initiation in callus
C. Somatic embryo - Embryo produced from a vegetative cell
D. Anther culture - Haploid plants

Explanation

To determine which of the following options is incorrectly matched, we will analyze each option step by step.

### Step 1: Understand the Terms
- **X plant**: This refers to an excised plant part used for callus formation.
- **Callus**: A group of undifferentiated cells that can develop into different types of plant tissues.
- **Cytokinin**: A type of plant hormone that promotes cell division and can influence root and shoot development.

### Step 2: Analyze Each Option
1. **X plant and Callus Formation**: This is correctly matched. X plants are indeed used to form callus.
2. **Cytokinin and Root Initiation**: This is incorrectly matched. Cytokinins primarily promote shoot formation rather than root initiation. High levels of cytokinin can inhibit root formation.
3. **Somatic Embryo and Vegetative Cell**: This is correctly matched. Somatic embryos can be produced from vegetative cells.
4. **Anther Culture and Haploid Plants**: This is correctly matched. Anther culture is a technique used to produce haploid plants.

### Step 3: Identify the Incorrect Match
From the analysis, the incorrect match is:
- **Cytokinin and Root Initiation** (Option B).

### Final Answer
The incorrectly matched option is **Option B**.
