This indicator provides information on the genetic distance between the varieties identified for the “Varietal Diversity” sub-indicator. Studies suggest that genetic diversification can help mitigate pest infestations, for example.
To determine the genetic diversity of cultivated fruit species, genetic analyses are conducted for the representative crop species wheat, potato, carrot, and apple. The diversity analyses are carried out using variety samples from the six reference years starting in 1920. The results can be used to interpret the development of genetic diversity in cultivation.
The goal of the genetic analysis is to identify varieties that carry alleles no longer available in current cultivation or in currently approved varieties. These varieties should be prioritized for ex-situ conservation and, in particular, reintroduced into cultivation through targeted on-farm management. If the genetic analyses of individual crops indicate an increasing genetic narrowing of current varieties, a targeted expansion of breeding programs can be promoted through appropriately designed funding programs.
