The conventional method of crop improvement involves several steps:

1. Selection of Parental Lines: In this step, suitable parental lines with desired traits are selected. These lines serve as the starting point for the breeding process.

2. Crossbreeding: The selected parental lines are crossbred to create new combinations of genes. This is done through controlled pollination, where the pollen from one parent is transferred to the flower of another parent.

3. Selection of Progeny: After crossbreeding, the resulting progeny plants are evaluated for their traits. The plants with desired traits, such as high yield, disease resistance, or improved quality, are selected for further breeding.

4. Repeated Selection and Breeding: The selected progeny plants are subjected to repeated cycles of selection and breeding. This helps to further enhance the desired traits and eliminate undesirable traits.

5. Testing and Evaluation: The selected plants are then tested and evaluated in different environments and conditions to assess their performance. This helps to ensure that the improved crops are adaptable and stable across different regions.

6. Release and Adoption: Once the improved crops have been thoroughly tested and proven to be superior, they are released for commercial cultivation. Farmers can then adopt these improved varieties to benefit from their improved traits.

It is important to note that the conventional method of crop improvement is a time-consuming process that can take several years to develop new varieties. However, it has been widely used and has contributed significantly to the development of improved crop varieties.
