Which of the following shows the correct sequence of steps involved in breeding a new genetic variety of a crop
(I) Selection and testing of superior recomnbinants (ii) Gerplasm collection (iii) Cross hybridisation among the selected parents (iv) Evaluation and selection (v) Testing, relases and commericalisation of new cultivars

Options

A. ii, iv, iii, i, and v
B. i, ii, iv, iii and v
C. iii, iv, i, ii and iv
D. ii, iii, i, iv and v

Answer

To determine the correct sequence of steps involved in breeding a new genetic variety of a crop, we can break down the process into the following steps:

1. **Germplasm Collection**: The first step in breeding a new crop variety is to collect germplasm, which refers to the genetic material (seeds, plants, etc.) that contains the genetic diversity needed for breeding.

2. **Evaluation and Selection of Parents**: After collecting the germplasm, the next step is to evaluate and select the most suitable parent plants that exhibit desirable traits for the breeding program.

3. **Cross Hybridization Among Selected Parents**: Once the parent plants are selected, the next step is to perform cross hybridization, where the selected parent plants are crossed to create new combinations of traits.

4. **Selection and Testing of Superior Recombinants**: After hybridization, the resulting offspring (recombinants) are evaluated, and the superior ones that exhibit the desired traits are selected and tested further.

5. **Testing, Release, and Commercialization of New Cultivars**: Finally, the selected superior recombinants undergo extensive testing to ensure they perform well under various conditions. Once confirmed, they are released and commercialized as new cultivars for farmers to use.

Thus, the correct sequence of steps is:
(ii) Germplasm collection → (iv) Evaluation and selection → (iii) Cross hybridization among the selected parents → (i) Selection and testing of superior recombinants → (v) Testing, release, and commercialization of new cultivars.

### Final Answer:
The correct sequence is: (ii) → (iv) → (iii) → (i) → (v).
