At present the application of techniques related to which branch is found time saving in crop improvement

Options

A. Cytology
B. Taxonomy
C. Plant physiology
D. Molecular Genetics

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which branch of science is currently applied in crop improvement techniques that save time.

2. **Analyzing the Options**:
- **Cytology**: This is the study of cells. While it is important in understanding plant structure, it does not directly relate to time-saving techniques in crop improvement.
- **Taxonomy**: This is the classification and identification of organisms. It is essential for understanding biodiversity but does not contribute directly to crop improvement techniques.
- **Plant Physiology**: This branch studies the functions and processes of plants. Although it provides valuable insights into plant growth and development, it is not primarily focused on time-saving techniques for crop improvement.
- **Molecular Genetics**: This field involves the study of genes at a molecular level and utilizes biotechnology for crop enhancement. Techniques such as genetic modification and gene editing (e.g., CRISPR) can lead to faster development of desirable traits in crops.

3. **Identifying the Correct Answer**: Among the options, molecular genetics is the branch that applies techniques for crop improvement that are time-saving. This is due to its ability to directly manipulate the genetic material of plants to achieve desired traits more quickly than traditional breeding methods.

4. **Conclusion**: The correct answer to the question is molecular genetics.

**Final Answer**: Molecular Genetics
