genetic-diversity
Genetic diversity refers to the variety of genetic characteristics within a plant species, encompassing variations from individual differences to population-level changes. In plant science, this diversity is fundamental to species survival and adaptation, enabling populations to respond to environmental stresses and providing the raw material for crop improvement through selective breeding. Maintaining adequate genetic diversity is essential for developing resilient crops with disease resistance and ensuring the long-term viability of cultivated and wild plant populations.
