wild-relatives
Wild relatives are the untamed ancestral and closely related species of domesticated crops that retain genetic diversity lost during agricultural breeding. These plants harbor valuable traits—such as drought tolerance, pest resistance, and disease immunity—that can be introgressed into cultivated varieties to improve resilience and yield. Studying and conserving wild relatives is essential for plant science as they represent an irreplaceable genetic reservoir for adapting crops to changing climates and emerging threats.

Wild relatives of wheat — grasses and ancient wheat species that thrive in harsh conditions — hold genetic traits that modern farmed wheat has lost. Scientists are using genomic tools and gene editing to bring those traits back, potentially creating wheat varieties that can withstand drought, disease, and climate disruption.
Wheat wild relatives carry genes for resistance to pests and diseases, tolerance to drought and salinity, and improved nutritional quality that have been lost in modern cultivated varieties.
Advances in genomic sequencing and CRISPR-style gene editing have significantly accelerated the transfer of beneficial wild traits into commercial wheat breeding programs.
De novo domestication — essentially re-domesticating wild plants from scratch using modern genomic tools — is emerging as a new strategy to develop resilient, high-yielding crops for future food security.
