GBS Dioscorea dumetorum
Yams are economically important food for millions of people in the humid and subhumid tropics. Dioscorea dumetorum is the most nutritious among the eight yam species commonly grown and consumed in West and Central Africa. Despite these qualities, the storage ability of D. dumetorum is restricted by severe post-harvest hardening of the tubers. The first step of any breeding program is bound to the study of genetic diversity. In this study, we used the Genotyping-By-Sequencing of Single Nucleotide Polymorphism (GBS-SNP) to reveal the genetic diversity and population structure of 43 accessions of D. dumetorum with 2 accessions of D. semperflorens, 1 accession of D. bulbifera and 1 accession of D. rotundata as outgroup species in Cameroon.
