Phytate Content

Cowpea is consumed as a staple food in many developing countries. The present study was undertaken to determine the variation in mineral elements and phytate concentrations in 30 cowpeas seeds varieties consumed in Burkina Faso. The composition of the thirty cowpeas seeds in total mineral varies from 5.08 % ± 0.00 to 3.55 % ± 0.08. The genotype CR06-07 showed the high content of total mineral (ashes) and the genotype Kondesyoungo local, the low content of ashes. IT81D-994 showed the high content of iron (7.07 ± 0.057 mg/100g of seeds dw), zinc (4.42 ± 0.012 mg/100 g of seeds dw), magnesium (239.80 ± 1.192 mg/100 g of seeds dw), calcium (123.39 ± 2.31 mg /100 g of seeds dw) and potassium (1201.97 ± 25.66 mg/100 g of seeds dw). Na and Se levels in the seeds showed about 4.5-fold and 7.6-fold variations between the cowpeas varieties. The genotype komcallé showed the high content of sodium (5.45 ± 0.20 mg/100 g of seeds dw) and the genotype KVx 414-22-2 had the high content of selenium (0.006 ± 0.0002 mg/100 g of seeds dw). The phytate content of the cowpeas genotypes varied from 555.61 ± 7.48 for TVU 14676 to 13.50 ± 1.14 mg/100 g of seeds dw for KVx 30-309-6G. The [Phy]/[Fe], [Phy]/[Zn], [Phy]/[Ca] and [Phy] x [Ca]/[Zn] ratios showed that the phytate content might compromise the Fe, Zn and Ca bioavailability in some cowpeas varieties. This study indicates that the cowpeas varieties might be considered as mineral source suitable for animal and human consumption.

SummaryComparative analysis of preferences and key criteria for selecting cowpea (Vigna unguiculata L. Walp.) varieties was conducted using the data collected from farmers’ participatory varietal selection (FPVS) activities conducted over 3 years with a total of 2401 farmers (1230 male and 1171 female) in 13 villages in Tougouri department in northern region and Tiéfora department in southern region of Burkina Faso in West Africa. Over the 3 years, farmer criteria for variety selection remained basically stable, but some variations among the regions and years were noticed. Grain yield was the most common and the most important criterion for farmers’ choice in both regions. Farmers in Tougouri (north) put more emphasis on early maturity (90%) and drought resistance (19.7%) as selection criteria than farmers in Tiéfora (south). Farmers in Tiéfora placed statistically significant importance on seed colour and plant type, while farmers in Tougouri did not, and for these selection criteria, there were only slight differences between genders in both areas. Results of stepwise multiple regression indicated that maturity and seed colour in the north, and seed size and seed colour in the south were the most important selection factors for farmers to select cowpea varieties. Improved varieties should have sufficiently good yield to be accepted, but other favoured traits may differ by target region as a reflection of local and regional market demands as well as deep-rooted cultural preferences. Understanding local and regional differences in selection criteria for cowpea varieties is necessary to improve the acceptance of newly released improved varieties. Preferences identified in the participatory activities could inform further development of cowpea breeding strategies for north and south regions of Burkina Faso.
