Which method is primarily used to preserve genetic diversity in crops?

• A. Gene therapy
• B. Seed banking
• C. Tissue culture
• D. Both seed banking and tissue culture

Answer: (D)

The preservation of genetic diversity in crops is crucial for maintaining food security, resilience to pests and diseases, and adaptability to changing environmental conditions. Seed banking is a primary method where seeds from various plant varieties are collected, stored, and preserved in controlled environments, ensuring that genetic material can be accessed in the future for breeding programs and restoration efforts. This approach helps safeguard against loss of genetic diversity, allowing for the reintroduction of seeds that might otherwise become extinct due to factors like climate change or habitat destruction. Tissue culture also plays a significant role in preserving genetic diversity. This method involves culturing plant cells or tissues in a nutrient medium, enabling the growth of new plants from a small number of cells. It helps maintain genetic integrity and allows for the regeneration of plants from rare or endangered varieties, further contributing to the preservation of crop diversity. Since both seed banking and tissue culture are effective methods for preserving genetic diversity in crops, the combined approach is particularly valuable. Utilizing both techniques strengthens the ability to maintain a diverse genetic repository, thereby enhancing the overall resilience of agricultural systems and supporting the goals of sustainable agriculture.
