KEYWORDS Cleome gynandra Selection Agromorphological characterization Burkina Faso ABSTRAC TPresent study was aimed to understand the scientific basis of the farmer's nomenclature of the local varieties of Cleome gynandra L. and to identify the characters of interests that can be used for the varietal improvement of the species. A survey was carried o ut in five cities of Burkina Faso with 56 producers of C. gynandra with the help of semi-structured interviews to identify the preferential characters. Furthermore thirty accessions were collected and evaluated in July 2014 at Gampela according to randomized complete block design with seventeen variables. T he study revealed that in the denomination of local varieties, the farmers use agromorphological characters such as the color of the stem, leaves and the vegetative cycle of the plant. It was also revealed that the selection of plant in the vegetable garden s is preferred for the green color of the stem, leaves, long vegetative cycle, height of the plant, dimensions of the leaves and the number of primary branches. T hese were the selective interests for the farmers identified during the survey. T he study also revealed that the process of selection is more advanced in Ouagado ugo u, where the demand is very high and where the consumers are more as compared to the other localities where the choice of the p lant has just began for consumption. T he results of this study have permitted to undertake the varietal improvement of the species according to the needs of the producers whose majority have a particular preference for the green ecotypes with long cycle.

In Burkina Faso, sweet grain sorghum [Sorghum bicolor (L.

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.
