This study is aimed at a better knowledge of the genetic diversity of H. cannabinus, a leafy vegetable which is very consumed in Burkina Faso. For this, a molecular characterization using SSRs microsatellite markers of 70 accessions collected in the three climatic zones of the country was carried out. The analysis shows significant genetic diversity among accessions, structured into three genetic groups. Indeed, 17 of the 20 markers tested were polymorphic. Expected unbiased heterozygosity ranged from 0.131 for marker MJM566 to 0.435 for marker MJM606 with an average of 0.309 for all primers. The Shannon diversity index (I) ranges from 1.552 for the primer MJM566 to 5.008 for the primer MJM606 with an average of 3.73 for all the primers tested. The organization of this genetic diversity is strongly influenced by the genetic group factor with a value of the differentiation index Fst of 0.324.
