A researcher identifies a naturally occuring variant possessing characteristics of interest . This plant is selectively bred. This is an example of

Options

A. Traditional plant breeding
B. Transgenic technology
C. Mutant selection
D. Cross breeding

Answer

To solve the question regarding the example of a researcher identifying a naturally occurring variant of a plant and selectively breeding it, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Context**: The question describes a scenario where a researcher finds a naturally occurring variant of a plant that has desirable traits. This is important because it indicates that the traits were not artificially created or modified through genetic engineering.

2. **Defining Selective Breeding**: Selective breeding is a process where specific plants with desirable traits are chosen to reproduce. This process aims to enhance certain characteristics in the offspring.

3. **Identifying the Type of Breeding**: Since the variant was found naturally and no genetic manipulation was involved, we need to categorize this breeding method. The options provided include:
- Traditional Plant Breeding
- Transgenic Technology
- Mutant Selection
- Cross Breeding

4. **Analyzing the Options**:
- **Traditional Plant Breeding**: This involves selecting plants with desirable traits and breeding them without altering their genetic makeup through modern techniques.
- **Transgenic Technology**: This involves genetic modification, which is not applicable here since the variant occurred naturally.
- **Mutant Selection**: This typically refers to selecting plants that have been induced to have mutations, which is not the case here.
- **Cross Breeding**: This involves breeding two different varieties to create hybrids, but the scenario describes selecting a single naturally occurring variant.

5. **Conclusion**: Given that the researcher is selectively breeding a naturally occurring variant without any genetic manipulation, the correct answer is **Traditional Plant Breeding**.

### Final Answer:
The example described is an instance of **Traditional Plant Breeding**.
