1. **Understanding the Question:**
The question asks about what selection is a method of, providing several options: cytology, plant physiology, plant breeding, and genetics.

2. **Analyzing the Options:**
- **Cytology:** This is the study of cells, which does not directly relate to the concept of selection in the context of breeding.
- **Plant Physiology:** This focuses on how plants function, including processes like photosynthesis and nutrient uptake, but does not involve selection methods.
- **Genetics:** This is the study of genes and heredity, which is important in understanding traits but does not specifically refer to the selection process itself.
- **Plant Breeding:** This is the manipulation of plants to develop desired traits, and selection is a crucial part of this process.

3. **Identifying the Correct Answer:**
Based on the analysis, the correct answer is **plant breeding**. In plant breeding, selection involves choosing the healthiest and finest plants from a crop to reproduce under controlled conditions.

4. **Conclusion:**
Therefore, selection is a method of **plant breeding**.
