Agro-morphological and molecular evaluations of local cowpea varieties (Vigna unguiculata (L.) Walp) at the Saria research station in Burkina Faso

Résumé

Local varieties could be a source of genetic variability. For this reason, six varieties were evaluated for agromorphological and molecular variability. A randomized Fisher's complement block with three replications was used. Pod pigmentation, seed size, stem habit and hilum color showed a difference in at least one of the 5
varieties. Statistical analysis was highly significant for the 50% flowering date parameter at 54.00±3.00 days after sowing (DAS) and highly significant for the 95% maturity parameter at 81.33±3.17 DAS compared with the control, which were around 43.00±0.00 DAS and 68.67±1.67 DAS. The best pod weights of around
3087.33±498.49 g and 3042.83±338.96 g with seed weights of around 18.00±0.32 g and 19.43±0.31 g were obtained by the Bengringa flat and round brown hilum varieties respectively, while the seed weights of Komcallé were 1733.46±526.54 g and 16.13±0.31 g respectively. 2.02±0.19 t/ha of haylage was obtained by the Bengraga B
variety, while Komcallé obtained 1.06±0.33 t/ha. The molecular markers used were unable to discriminate between the varieties.
