Genetic diversity is the basis of plant breeding. This study aims to determine the level and the organization of the genetic diversity within spider plant genetic resources in Burkina Faso, using ten (10) polymorphic markers Inter Simple Sequence Repeat (ISSR). A total of 40 alleles were identified with an average of 4 alleles per locus and 2.919 effective alleles. The expected heterozygosity and the Shannon's diversity index were respectively 0.279 and 1.695. The analysis of the structuration of the genetic diversity allowed identifying three significantly different groups. These results revealed a relatively low diversity. Although the variations between the cultivated and spontaneous accessions are weak, they indicate a beginning of organization of genetic diversity according to the selection.
