Which one of the following is an example of somatic hybridisation

Options

A. Bt cotton
B. Pomato
C. Golden rice
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Somatic Hybridization**: Somatic hybridization is a technique in plant breeding that involves the fusion of protoplasts (the living part of a plant cell without the cell wall) from two different plant species. This process allows for the combination of genetic material from different plants to create a hybrid.

2. **Analyzing the Options**:
- **Option 1: Bt Cotton**: This is a genetically modified organism (GMO) created through genetic engineering to express a bacterial gene for pest resistance. It does not involve somatic hybridization.
- **Option 2: Permato**: This is a hybrid plant created by fusing protoplasts from potato and tomato, both of which belong to the Solanaceae family. This is a clear example of somatic hybridization.
- **Option 3: Golden Rice**: This is another GMO developed to produce beta-carotene (a source of vitamin A) through genetic engineering, not somatic hybridization.
- **Option 4: All of these**: This option suggests that all the previous examples are instances of somatic hybridization, which is incorrect.

3. **Identifying the Correct Answer**: Based on the analysis, the only option that represents somatic hybridization is **Permato** (Option 2).

4. **Conclusion**: The correct answer to the question "Which one of the following is an example of somatic hybridization?" is **Permato**.
