Molecular Characterization of Corchorus olitorius L. of Burkina Faso

Corchorus olitorius is more and more cultivated in Burkina Faso because of its socio - economic interest. Hence the objective of this study which will contribute to improve the knowledge of the genetic diversity of the species in Burkina Faso. To this end, seventeen SSR markers were used to characterize ninety-six (96) accessions of the four phytogeographic sectors of Burkina Faso. These accessions consist of 16 accessions of the variety C. olitorius var insicifolius and 80 accessions of the variety C. olitorius var olitorius. The results of the analysis of the diversity of microsatellite markers tested, they were seized sixteen (16) of the seventeen (17) SSRs are polymorphic with a rate of polymorphism of 92.19 % and number of 53 alleles with a mean of three (3) alleles per locus. As for the Shannon diversity index, with an average of 1.05, it is between 0.53 for the HK-27 marker and 1.90 for the HK-19 marker. The polymorphism information content (PIC) potential ranged from 0.11 for the HK-12 marker to 0.49 for the HK-6 marker with an average of 0.32. A structure of diversity into three groups regardless of phytogeographic areas or botanical variety has always been.
