Genetic analysis reveals that some specialty coffee seeds do not match their commercial identity
Genetic analysis revealed that several seeds from a batch sold as Sidra were not, in fact, Sidra; their genetic profile was closer to that of Batian, a Kenyan variety.
Genetic analysis has revealed that some specialty coffee seeds sold under specific identities did not match their commercial names. Researchers from the Universidad Técnica Particular de Loja in Ecuador studied four morphotypes of plants grown from seeds labeled as Sidra and Gesha. Only two of the four morphotypes aligned with the expected varieties.
One Sidra morphotype was actually genetically similar to Batian, a Kenyan variety, while Gesha plants differed from a reference accession known as Geisha T.02722. The study highlights the importance of accessible identification tools and certification systems for producers, as the discrepancy between planted material and declared variety can only be detected after years of investment and work.
