Abstract
Soybean is one of the main food crops in Democratic Republic of Congo (DRC). Its production is ensured mainly by farmers who use seeds of various origins. However, yields obtained with this crop remain low because of seed-borne diseases that also affect the quality of the seeds.
Twenty – two batches of seeds collected in the Democratic Republic of Congo were analyzed. The average values of weight purity recorded ranged from 79 to 100 %, germination rates from 0 % to 86.6 % and seed weight from 71.1 to 152 g. Several phytopathogenic agents have been identified on both certified variety and landraces. The fungus Fusarium solani F.sp Glycine, Aspergillus sp, Rhizoctonia solani, Phomopsis longicola, Xanthomonas axonopodis pv. Glycine and Pseudomonas syringae pv Glycine have been identified.
