Abstract

A key component of sustainable development aimed at addressing poverty, malnutrition and improving livelihoods is crop genetic diversity. It is necessary that plant genetic diversity must be conserved and utilized for meeting future growth requirements and ensuring food security directly impacting health and environmental sustainability. It is crucial to conserve and utilize crop genetic diversity to develop new plant gene combinations for crop varieties suited to diverse agricultural conditions and capable of withstanding environmental stresses. Crop genetic resources, stored in gene banks and other repositories are invaluable reservoirs of genetic diversity, safeguarding plant species from climate change and human driven homogenization of agricultural landscapes. Understanding the distribution of genetic variation in crops is critical for preserving and harnessing that variation to address challenges posed by changing markets, climate and agricultural approaches. Lack of genetic diversity limits breeding advancement and the ability to enhance crop productivity and quality. As the global climate changes, ensuring availability and access to diverse genetic resources is essential to enable worldwide farming industry to adapt and satisfy the growing demands of expanding population. Sustainable development and food security depend on the conservation and exploitation of agricultural biodiversity, integrating genetic diversity and crop improvement as inalienable strategies for sustainable agriculture and the conservation of biodiversity.
