Abstract excerpt

Understanding crop genetic diversity is essential for conservation and breeding, yet farmer-maintained germplasm remains largely underrepresented in genomic studies. Theobroma cacao L. has a complex domestication history, extensive global diversity, and is currently cultivated in Central America. Costa Rican cacao has been understudied compared to South American and Mexican cultivars despite cultural and...
