Flavr savr variety of Tomato is improved variety developed through

Options

A. Hybridisation between old varieties
B. Hybridisation between a modern variety and a wild variety
C. Mutation variety
D. Incorporation of a transgene

Answer

**Step-by-Step Solution:**

1. **Understanding the Flavr Savr Tomato**: The Flavr Savr tomato is a genetically modified variety developed to enhance its shelf life and reduce post-harvest losses. This is crucial for maintaining the quality of tomatoes during storage and transportation.

2. **Identifying the Development Method**: The question asks about the method used to develop the Flavr Savr tomato. The options provided likely include hybridization, mutation breeding, and genetic engineering (transgene incorporation).

3. **Eliminating Incorrect Options**:
- **Hybridization**: This method involves crossing different varieties to produce offspring with desired traits. The Flavr Savr tomato is not a result of hybridization, so this option can be eliminated.
- **Mutation Breeding**: This involves inducing mutations to create new traits. However, the Flavr Savr tomato was not developed through this method, so this option is also incorrect.

4. **Correct Method - Incorporation of a Transgene**: The Flavr Savr tomato was developed using genetic engineering techniques, specifically through the incorporation of a transgene. This involved blocking a native tomato gene responsible for producing the enzyme polygalacturonase, which causes fruit softening.

5. **Conclusion**: The correct answer to the question is that the Flavr Savr variety of tomato was developed through the incorporation of a transgene.

**Final Answer**: The Flavr Savr variety of tomato is an improved variety developed through the incorporation of a transgene.
