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

Explanation

To answer the question, "A collection of all the alleles of all the genes of a crop plant is called," we will analyze the options provided and identify the correct term.

### Step-by-Step Solution:

1. **Understanding the Terminology**:
- The question refers to a collection of all alleles (variations of genes) of all the genes in a crop plant. This concept is crucial in genetics and plant breeding.

2. **Evaluating the Options**:
- **Option A: Germplasm Collection**: This refers to the genetic material (alleles and genes) of a plant that can be used for breeding and conservation purposes. It includes all the genetic diversity available in a crop species.
- **Option B: Protoplasm Collection**: Protoplasm refers to the living contents of a cell, which does not include genetic material in the context of heritable traits.
- **Option C: Herbarium**: A herbarium is a collection of preserved plant specimens and does not pertain to genetic material.
- **Option D: Somoclonal Collection**: This refers to a collection of somatic cells, which are not directly related to the alleles of genes.

3. **Identifying the Correct Answer**:
- Since the question specifically asks for a collection of alleles of all genes in a crop plant, the correct answer is **Option A: Germplasm Collection**.

### Final Answer:
The collection of all the alleles of all the genes of a crop plant is called **Germplasm Collection**.
