The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Plant Breeding**: Plant breeding is the process of altering the genetic makeup of crop plants to create desirable traits. This involves various steps to ensure that the new cultivars are superior and suitable for cultivation. 2. **Collection of Variability**: The first step in plant breeding is to collect and preserve a wide range of genetic material. This includes wild varieties, species, and relatives of the cultivated crops. This genetic diversity is crucial for breeding programs. 3. **Evaluation and Selection of Parents**: After collecting variability, the next step is to evaluate and select the parent plants that will be used for hybridization. These selected plants are multiplied, and pure lines may be developed if necessary. 4. **Cross-Hybridization**: The selected parent plants are then cross-hybridized. This process involves mating two different plants to produce hybrids that possess desirable traits from both parents. 5. **Selection and Testing of Superior Recombinants**: Once hybridization occurs, the next step is to select and test the resulting plants (recombinants). The goal is to identify plants that exhibit superior characteristics compared to their parents. 6. **Testing and Commercialization**: Before a new cultivar can be released for commercialization, it must undergo extensive testing. This involves evaluating the performance of the new crop in various conditions, including fertilizer application and irrigation practices. 7. **Field Testing Duration**: Specifically, the new cultivar must be tested in farmers' fields for at least three growing seasons across different locations. This ensures that the crop is resilient and performs well in diverse agricultural settings. 8. **Final Release**: After successful testing and evaluation, the crop can then be officially released for commercialization, allowing farmers to cultivate the new variety. ### Final Answer: A crop must be tested for at least **three growing seasons** before it can be released for commercialization. ---
