In plant breeding programme, the entire collection (of plants/seed) having all the diverse alleles for all genes in a given crop is called

Options

A. evaluation and selection of parents
B. germplasm collection
C. Selection of superior recombinants
D. Cross - hybridisation among the selected parents

Answer

To solve the question regarding the term used in plant breeding programs for the entire collection of plants or seeds that have all the diverse alleles for all genes in a given crop, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context of Plant Breeding**:
- Plant breeding involves various techniques to improve crop varieties. This includes collecting genetic diversity, evaluating traits, hybridization, and selecting superior offspring.

2. **Identify Key Terms**:
- The question specifically asks for a term that refers to a collection that encompasses all genetic diversity (alleles) for a given crop.

3. **Recall the Process of Plant Breeding**:
- The first step in plant breeding is to gather all the variability present in the crop. This means collecting different varieties of the plant that possess various traits.

4. **Define the Collection of Genetic Material**:
- The collection that includes all the diverse alleles for all genes in a crop is crucial for breeding programs as it serves as the genetic reservoir.

5. **Arrive at the Correct Term**:
- The term that describes this comprehensive collection of genetic material in plant breeding is known as "germplasm collection."

### Final Answer:
The entire collection of plants or seeds having all the diverse alleles for all genes in a given crop is called **germplasm collection**.
