Answer

To produce a new genetic variety of a crop, the following sequential steps are involved:

### Step-by-Step Solution:

1. **Collection of Variability (Germplasm Collection)**:
- The first step is to gather a diverse range of genetic material from existing crops. This is crucial as it provides the necessary genetic diversity needed for breeding.

2. **Evaluation and Selection of Parents**:
- Once variability is collected, the next step is to evaluate the collected germplasm and select the most suitable parent plants based on desired traits such as yield, disease resistance, and environmental adaptability.

3. **Cross Hybridization**:
- After selecting the parent plants, the third step involves cross hybridization. This is the process of mating selected parent plants to create hybrid offspring that combine the desirable traits of both parents.

4. **Testing of Superior Recombinants**:
- The hybrids produced from cross hybridization are then tested to identify superior recombinants. This involves evaluating the hybrids for their performance in terms of growth, yield, and resistance to diseases.

5. **Release and Commercialization of New Cultivars**:
- The final step is to release the new genetic variety (cultivar) to the market. This includes commercialization, which involves making the new crop variety available to farmers and ensuring it meets regulatory standards.
