Isolated protoplasts from two different varieties of plants , can be fused to get hybrid protoplast. These hybrids are called

Options

A. Somaclones
B. Somatic hybrids
C. Gametic hybrids
D. Cytoplasmic hybrids

Answer

To solve the question regarding the fusion of isolated protoplasts from two different varieties of plants, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Protoplasts**:
- A protoplast is a plant cell that has had its cell wall removed. This is typically achieved using enzymes like cellulase or pectinase.

2. **Fusion of Protoplasts**:
- When protoplasts from two different varieties of plants are isolated and then fused together, they form a hybrid protoplast.

3. **Identifying the Type of Hybrid**:
- The resulting hybrid protoplast from the fusion of two different protoplasts is specifically referred to as a **somatic hybrid**. This process is known as **somatic hybridization**.

4. **Evaluating Other Options**:
- **Somaclones**: These are genetically identical plants produced through tissue culture, not through protoplast fusion.
- **Gametic Hybrids**: These hybrids are formed from the fusion of gametes (sperm and egg) and are not related to protoplast fusion.
- **Cytoplasmic Hybrids**: These are formed by fusing a complete cell with a cytoplast (an enucleated cell), which is different from the fusion of protoplasts.

5. **Conclusion**:
- Based on the definitions and processes described, the correct answer to the question is that the hybrids formed from the fusion of isolated protoplasts from two different varieties of plants are called **somatic hybrids**.

### Final Answer:
**Somatic hybrids**
