ABSTRACT
Background: The assessment of genetic diversity is an asset for the development of any varietal conservation and improvement
strategy. Methods: This work aims to establish the level and structure of genetic diversity of 54 accessions of amaranth collected in
two climatic zones (Sudanese zone and Sudano-Sahelian zone) of Burkina Faso. Fourteen (14) ISSRs markers developed by
eurofinmwg/ Operon were used in this study. Results: Eight (8) of them were been polymorph and used for data analysis. All eight
primers showed 100% polymorphism with an average PIC of 64%. A total of 40 alleles were revealed with an average of 5 alleles by
locus. Also, an average of effective allele number of 3.94, a heterozygoty expected of 0.37 and Shannon diversity indexes of 1.3 were
recorded. These parameters calculated showed that the markers used are informative and revealed an important genetic variability
structured in four groups (A, B, C and D) within the collection amaranth cultivated in Burkina Faso. The influence of "climatic zone" and
"morphotype" factors on the level and the organization of genetic diversity is very low. Conclusion: 98.80% of total genetic diversity
is due to variability intra-population.
