Best method to preserve the wild relatives of plants:-

Options

A. By growing them in natural habitats
B. Gene library
C. By storing seeds
D. Cryopreservation

Answer

**Step-by-Step Solution:**

1. **Understanding Wild Relatives of Plants**: Wild relatives of cultivated plants are species that have not been domesticated but share a genetic relationship with domesticated crops. They are important because they often possess desirable traits such as disease resistance and adaptability to harsh conditions.

2. **Importance of Preservation**: Preserving these wild relatives is crucial for maintaining biodiversity and ensuring food security. They can provide genetic material that can be used to improve cultivated varieties.

3. **Methods of Preservation**: There are two main methods for preserving wild relatives:
- **In-situ Conservation**: This involves preserving the wild relatives in their natural habitats. This method allows for the natural interactions between the plants and their environment, which can enhance their growth and survival.
- **Ex-situ Conservation**: This involves preserving the wild relatives outside their natural habitat, such as in seed banks or botanical gardens. While this method is useful, it may not provide the same ecological benefits as in-situ conservation.

4. **Best Method**: The best method to preserve wild relatives of plants is through **in-situ conservation**. By allowing these plants to grow in their natural habitat, they can interact with their ecosystem, which helps maintain their genetic diversity and resilience.

5. **Conclusion**: In-situ conservation is the most effective way to preserve wild relatives of plants, as it supports their natural growth conditions and interactions with other species.
