While planning for an articifical hybridisation programmme involving dioecious plants, which of the following steps would not be relevant?

Options

A. Bagging of female flower
B. Dusting of pollen on stigma
C. Emasculation
D. Collection of pollen

Answer

To solve the question regarding the steps that would not be relevant in an artificial hybridization program involving dioecious plants, we can follow these steps:

### Step 1: Understand Dioecious Plants
Dioecious plants are those that have male and female reproductive organs on separate individuals. This means that self-pollination cannot occur because a single plant cannot provide both pollen and ovules.

### Step 2: Identify Relevant Steps in Artificial Hybridization
In artificial hybridization, the following steps are typically involved:
1. **Emasculation**: This is the process of removing the anthers from a flower to prevent self-pollination.
2. **Bagging**: Covering the flower with a bag to protect it from unwanted pollen before it is pollinated.
3. **Pollen Collection**: Gathering pollen from a male plant or pollen bank.
4. **Pollination**: Dusting the collected pollen onto the stigma of the female flower.

### Step 3: Analyze the Steps for Dioecious Plants
Since dioecious plants already have separate male and female plants, self-pollination is inherently prevented. Therefore, emasculation (removing anthers) is not necessary because there are no anthers on the female plant to remove.

### Step 4: Conclusion
The step that would not be relevant in an artificial hybridization program involving dioecious plants is **emasculation**.

### Final Answer
**Emasculation** is the step that would not be relevant in an artificial hybridization program involving dioecious plants.
