Protoplast fusion results in

Options

A. Parasexual/somatic hybridisation
B. Genetic hybridisation
C. Male sterility
D. Rapid growth and acclimitisation.

Answer

### Step-by-Step Solution:

1. **Understanding Protoplast Fusion**: Protoplast fusion is a biotechnological technique where the cell walls of two different plant cells (protoplasts) are removed and the resulting protoplasts are fused together to form a hybrid cell.

2. **Purpose of Protoplast Fusion**: The primary goal of protoplast fusion is to create hybrid plants that possess desirable traits from both parent plants. This technique allows for the combination of genetic material from different species or varieties.

3. **Formation of Hybrid Cells**: Once the protoplasts are fused, they form a hybrid cell. This hybrid cell can then be cultured on nutrient media to encourage growth and development into a new plant.

4. **Genetic Variation**: The hybrid cells created through protoplast fusion exhibit variations in their genetic makeup. This is due to the mixing of the gene pools from the parent plants, which can lead to new traits and characteristics.

5. **Terminology**: The variations resulting from protoplast fusion are referred to as somatic hybridization. This term is used because the fusion occurs at the somatic (non-reproductive) cell level.

6. **Conclusion**: Based on the explanation, protoplast fusion results in "parasexual and somatic hybridization," which is option A.

### Final Answer:
The correct answer is **A. parasexual/somatic hybridization**.
