First step in plant breeding programmes is :

Options

A. Selection of superior recombinants
B. Cross hybridization of selected parents
C. Germplasm collection
D. Introduction of exotic species

Answer

### Step-by-Step Solution:

1. **Understanding Plant Breeding**: Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. This process involves several steps to improve plant varieties.

2. **Identifying the First Step**: The first step in any plant breeding program is crucial as it sets the foundation for all subsequent activities.

3. **Germplasm Collection**: The first step is the collection of germplasm. Germplasm refers to the living genetic resources, such as seeds or tissues, that are maintained for breeding purposes. This collection is essential as it provides the genetic diversity needed for breeding programs.

4. **Selection of Superior Recombinants**: After germplasm collection, the next step typically involves selecting superior recombinants from the collected germplasm. This involves identifying plants with desirable traits for further breeding.

5. **Cross Hybridization**: Once the superior parents are selected, cross hybridization of these selected parents can be performed to create new plant varieties.

6. **Introduction of Exotic Species**: In some cases, introducing exotic species may also be part of the breeding program to enhance genetic diversity or introduce new traits.

### Final Answer:
The first step in plant breeding programs is **germplasm collection**.
