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. germaplasm collection
C. selection for superior recombinants
D. cross hybridiation among the selected parents

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for the term used in plant breeding programs to describe a collection of plants or seeds that contains all the diverse alleles for all genes in a specific crop.

2. **Identifying the Options:**
The options provided are:
- A) Evaluation and selection of parents
- B) Germplasm collection
- C) Selection for superior recombinants
- D) Cross hybridization among the selected parents

3. **Analyzing the Options:**
- **A) Evaluation and selection of parents:** This refers to the process of choosing parent plants based on desirable traits, but it does not encompass the entire collection of genetic material.
- **B) Germplasm collection:** This term refers to the collection of genetic material (seeds or plants) that includes all the diverse alleles for all genes in a crop. This is the most relevant option.
- **C) Selection for superior recombinants:** This involves selecting offspring that exhibit desirable traits, but it does not refer to the collection of genetic material.
- **D) Cross hybridization among the selected parents:** This is a breeding technique used to create new combinations of traits, but it does not describe the collection of genetic diversity.

4. **Conclusion:**
Based on the analysis, the correct answer is **B) Germplasm collection**. This term specifically refers to the entire collection of genetic material that includes all the diverse alleles for all genes in a given crop.

5. **Final Answer:**
In plant breeding programs, the entire collection of plants/seeds having all the diverse alleles for all genes in a given crop is called **germplasm collection**.
