A collection of all the alleles of all the genes of a crop plant is called

Options

A. germplasm collection
B. protoplasm collection
C. herbarium
D. somaclonal collection

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes a collection of all the alleles of all the genes of a crop plant. This is a specific term used in genetics and plant breeding.

2. **Identifying the Options**: The options provided include:
- Germplasm collection
- Protoplasm collection
- Somaclonal collection
- Herbarium

3. **Analyzing Each Option**:
- **Germplasm Collection**: This refers to the collection of genetic material (seeds, plants) that includes diverse alleles of all genes in a crop. It is crucial for crop improvement and breeding programs.
- **Protoplasm Collection**: This term is not commonly used in plant genetics and does not refer to a collection of alleles.
- **Somaclonal Collection**: This term refers to genetic variations that occur in plants regenerated from tissue culture, but it does not encompass all alleles of all genes.
- **Herbarium**: This is a collection of preserved plant specimens and their data, but it does not specifically relate to alleles or genetic material.

4. **Conclusion**: Based on the analysis, the correct answer is **Germplasm Collection**. This term accurately describes a collection of all the alleles of all the genes of a crop plant.

**Final Answer**: Germplasm collection
