Antioxidant compounds of dietary plants have been widely studied because of their bioactive properties. The objective of this research study was to analyse the health enhancing attributes of 31 cowpeas varieties from Burkina Faso. Significant variations were observed in the phenolic content as well as the antioxidant and anti-lipid peroxidation activities amongst the cowpea varieties. Pearson correlation coefficient analysis showed that the ferric reducing ability (r = 0.954) and anti-lipid peroxidation (r = 0.616) were positively correlated with the total phenolic content. A significant relationship between cowpea ferric reducing ability and anti-lipid peroxidation (r = 0.64) was also revealed. However, nitric oxide scavenging potential was found not to be related to its total phenolic and total flavonoid content. 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydroxyl radicals scavenging potentials were not correlated with the total flavonoid content. The pigmented seeds of cowpea varieties possess higher total phenolic, total flavonoid content, ferric reduction ability, and anti-lipid peroxidation activities than the colourless ones. The results obtained from this study suggest that Burkina Faso cowpea cultivars are rich in phenolic compounds and have significant antioxidant and anti-lipid peroxidation activities. Consumption of the cowpea, particularly of coloured cowpea seed varieties, should be beneficial for chronic human diseases prevention.

Decisions on the choice of varieties to be planted in a region are delicate because they can have positive or negative long-term consequences on the economic, environmental and nutritional level of a country. For this reason, a multi-criteria decision making (MCDM) based approach is proposed to conduct this choosing process. The proposed approach first of all makes it possible to identify alternatives, i.e. agricultural varieties, criteria with their weighting and evaluation process, in interaction with the stakeholders in the production-processing-consumption food chain. Afterward, PROMETHEE method (I and II) is used to aggregate the preference informations stemming from the structuring process and make it possible to choose the best agricultural varieties suitable for a given region. An Application for the selection of suitable cowpea varieties for the Central-Eastern region of Burkina Faso is made to demonstrate the implementation and effectiveness of our approach. As a result, the varieties KVx442-3-25SH (Komcallé) and Yiis-Yandé emerged as the best choices of suitable cowpea varieties for the Central-Eastern region of Burkina Faso

Success of cowpea cultivation requires a strong understanding of production constraints in order to overcome them. It is thus useful to know whether smallholder cowpea growers use modern or indigenous means to overcome these challenges. We completed a participatory rural appraisal (PRA) study to identify current cowpea production constraints and management practices in Burkina Faso. We interviewed 481 cowpea growers (219 women and 262 men) and used a mixed-method design of collecting both qualitative and quantitative data. The results showed that water scarcity, damage due to insects, plant diseases, striga, lack of training, and marketing challenges are the main constraints to cowpea production. Among insects reducing cowpea yield, growers identified aphids as a major pest. However, growers often did not know the biology and incidence of insects in their fields. This study also identified local resistant cowpea varieties in various locations.

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.

Objectif : La présente étude vise à une meilleure connaissance du niébé vert par l’évaluation des performances agronomiques de douze (12) variétés. Méthodologie et résultats : Les variétés ont été évaluées par douze (12) variables quantitatives dans un dispositif en bloc de Fisher avec trois (3) répétitions à l’INERA/Kamboinsé en 2018. L’étude a montré l’existence d’une grande variabilité agronomique au sein des variétés étudiées. Des corrélations positives et significatives ont été aussi observées entre les variables. L’Analyse en Composante Principale (ACP) des variables a permis d’identifier la date 50% floraison, le SPAD, la date niébé vert, la date 95% maturité, le nombre de graines par gousse, le poids gousses, le poids graines, le poids fanes, le rendement graines et fanes comme les paramètres les plus pertinents qui discriminent les variétés. La meilleure variété a été le niébé baguette grimpant qui possédait une date niébé vert (50 jours) et une maturité (63 jours) précoce. Conclusion et application des résultats : La variété IT83S-872 a été identifiée comme très productive en termes de gousses (77 gousses). La variété Komsaré a obtenu un rendement en graines (2,72 t/ha) et en fanes (3,20 t/ha) très appréciables. Cependant, la variété IT85F-2887 s’est montrée exceptionnelle, car en plus d’avoir une date de niébé (50 jours) vert et une maturité précoce (65 jours), elle a présenté un bon rendement en graines (2,63 t/ha) et le meilleur rendement en fanes (3,67 t/ha). Ces variétés précoces, productives en graines et en fourrage pourront être des substituts du haricot vert et contribuer efficacement à l’amélioration de la production du niébé au Burkina Faso.

Methodology and results: The varieties were evaluated in a randomized complete block design (RCBD) with three (03) replications using 12 quantitative variables at the Kamboinsé research station 2018. The study revealed the existence of important agronomic variability within the studied varieties. Positive and significant correlations were also observed between variables. Principal Component Analysis (PCA) identified days to 50% flowering; the chlorophyll content (SPAD); days to vegetable cowpea; days to 95% maturity; number of seeds per pod, pods weight, seeds weight, fodder weight, seeds yield and fodder yield as the most relevant parameters. The best variety was niébé baguette grimpant, with the earliest days to vegetable cowpea (50 days) and days to maturity (63 days). Conclusion and application of results: The variety IT83S-872 has been identified as the highest pods productive (77 pods). The variety Komsare recorded a very appreciable seeds (2.72 t/ha) and fodder (3.20 t/ha) yield. However, the variety IT85F-2887 was exceptional, in addition to its earliness for days to vegetable cowpea (50 days) and days to maturity (65 days), it recorded the best seeds (2.63 t/ha) and fodder (3.67 t/ha) yields. These early maturing, high seeds and fodder producing varieties, could substitute common beans and effectively contribute to the improvement of cowpea production in Burkina Faso. Key words: Vegetable cowpea, agronomic performance, fodder, Burkina Faso.

Full textAbstract:
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.

Full textAbstract:
Resilience of smallholder farmers in their ability to bounce-back and overcome shocks, such as drought, is critical to ensure a pathway out of hunger and poverty. Efficient water conservation methods that increase rainwater capture and reduce soil erosion such as stone lines and grass bands are two technologies that have been proposed to increase the resilience in Sudano–Sahelian farming systems. In Burkina Faso, we show that stone lines, grass bands, and crop rotation are effective resilience strategies individually and in combination. During years when rainfall is well-distributed over time, differences are minimal between fields with water conservation methods and fields without. However, when there are periods of prolonged drought, water conservation methods are effective for increasing soil water, yield, revenue, and resilience. During drought conditions, sorghum (Sorghum bicolor (L.) Moench) grain yield and revenue with stone lines and grass bands were over 50% greater than that of the control, by an average of 450 kg ha−1, which amounted to an increase of 58,500 West African CFA franc (CFA) ha−1 (i.e., 98 USD ha−1). The results also suggest that the combination of water conservation method and crop rotation additionally improves cropping system productivity and revenue. Growing cowpea (Vigna unguiculata (L.) Walp.) in rotation with sorghum production provided more options for farmers to increase their income and access to nutrition. This study also sheds light on the limited productivity gains due to improved crop varieties. The local sorghum landrace, Nongomsoba, and the local cowpea variety in rotation resulted in the highest yields as compared to the improved varieties of Sariaso 14 sorghum and KVX 396-4-4 cowpea. Under similar low input/degraded conditions, improved crop varieties likely are not a suitable resilience strategy alone. We conclude that during erratic rainy seasons with frequent periods of drought (i.e., water stress) in rain-fed conditions in Burkina Faso, stone lines or grass bands in combination with sorghum and cowpea rotation are effective practices for increasing resilience of smallholder farmers to maintain crop productivity and revenue. With future and present increases in climate variability due to climate change, stone lines, grass bands, and crop rotation will have growing importance as resilience strategies to buffer crop productivity and revenue during periods of drought.

Full textAbstract:
Alectra vogelii Benth. is the second most important parasitic weed in cowpea [Vigna unguiculata (L.) Walp.] production in Burkina Faso. Several resistant varieties to this weed have been identified in the country among which are B301 and KVx414-22-2. The inheritance and allelic relationships of the resistance genes in the two varieties have not been studied with A. vogelii strains in Burkina Faso. The objective of this study was to determine the inheritance and allelic relationship of the resistance genes in B301 and KVx414-22-2. To determine the inheritance of the genes for resistance, the resistant varieties (B301 and KVx414-22-2) were each crossed to a susceptible variety IT82D-849 to generate F1 and F2 populations. For the allelic relationship study the two resistant genotypes were crossed among themselves to generate F1 and F2 offspring. The parents and their F1 and F2 progenies were screened in artificially infested pots with Alectra seed in a screen house at Kamboinsé Research Station in Burkina Faso. Resistance/susceptibility of genotypes was assessed by recording the number of emerged Alectra shoots. The data were subjected to the Chi-Square goodness-of-fit test for one, two and three genes segregation ratios. The results revealed that two independent dominant genes confer resistance in the variety B301 and a single dominant gene confers resistance in variety KVx414-22-2. The single dominant gene in KVx414-22-2 is non-allelic to the two genes in B301. The two resistance genes in variety B301 have already been named Rav1 and Rav2 whilst Rav3 is the name of the resistance gene in variety IT81D-994. Therefore, we propose the symbol Rav4 as the name for the resistance gene in variety KVx414-22-2.

Full textAbstract:
In Burkina Faso, the existence of different races of Striga gesnerioides (Willd.) Vatke, with
apparent variable aggressiveness on cowpea (Vigna unguiculata (L.) Walp) renders the
breeding task very complex. Therefore, a number of studies was carried out from 2006 to
2009 in field, pot and ‘’in-vitro’’ to identify new sources of resistance to three prevailing
Striga races, SR 1, SR 5 and a newly occurring Striga race named SR Kp and to
understand the genetic pattern of the underlying resistance of cowpea germplasm to Striga
races found in Burkina Faso.
To achieve these objectives, the following investigations were initiated: (i) a participatory
rural appraisal (PRA), a participatory variety selection (PVS) and grain quality survey were
implemented to identify cowpea breeding priorities for Burkina Faso Striga hot-spots; (ii) the
identification of sources of resistance in Burkina Faso germplasm, using three prevailing
Striga races of S. gesnerioides as sources of inoculum; (iii) the identification of the
mechanisms of resistance underlying the resistance to Striga in such genotypes; (iv) a
study of combining abilities of selected parents through a diallel cross; (v) a study of the
segregation patterns in crosses involving resistant and susceptible sources and a study of
the allelic relationships between different resistance sources.
The participatory studies conducted in 2007 and 2008 over three districts in Striga hotspots;
there was no effective control method against Striga at farmers’ level. These
investigations highlighted the importance of cowpea across all sites. Rain decline over time,
low input use coupled with a poor extension system were the major constraints mentioned
by farmers. Differential reactions of genotype KVx61-1 for Striga resistance suggested that
different Striga races were prevailing in different areas. Farmers’ preferred traits in cowpea
genotypes were oriented towards grain quality such as big sized grain, white seed colour
and rough texture of cowpea grain, except in Northern-Burkina Faso, where farmers
preferred brown-coloured grain for food. Cowpea was also seen as an income generating
crop.
An evaluation of 108 genotypes was done in 2007 in the field (rainy season) and in pots
(off-season) for Striga resistance assessments. The screening trials enabled the
identification of sources of resistance to S. gesnerioides. Genotypes KVx771-10, IT93K-
693-2, KVx775-33-2, Melakh and IT81D-994 are potential sources of resistance to all three
Striga races with acceptable yield. Landraces were susceptible and late-maturing whilst
most wild species were resistant but with unwanted shattering traits.
A combining ability study for Striga resistance parameters conducted in pots and a
resistance mechanism study conducted ‘’in-vitro’’ were performed using F1 populations from
a 10 x 10 diallel cross. The general combining ability (GCA) effects were significant for the
resistance parameters Striga emergence date (DSE), Striga height above soil (SH), cowpea
grain weight (CGW), hundred grain weight (HGW) for all Striga races involved and Striga
vigour (SVIG) for SR 5 and SR Kp. The pot-screening showed that, regardless of the SR
used as inoculum, the additive genes were important in conferring Striga resistance for
parameters DSE, SH, CGW and HGW. The selection of parents could therefore result in
breeding advance. Complete dominance, partial, over-dominance and non-allelic
interactions (epistasis or failure of some assumptions) were present for some parameters.
The ‘’in-vitro’’ screening showed that additive genes were important, with high narrow sense
heritability values for the resistance mechanisms Striga seed germination frequency (GR)
for SR 1 and SR Kp, the frequency of Striga radicle necrosis before the penetration in
cowpea rootlet (NBP) for SR 5, the frequency of Striga radicle necrosis after the penetration
in cowpea rootlet (NAP) for SR 1 and SR Kp and the susceptibility ‘’in-vitro’’ (SIV) for SR 5
and SR Kp. The selection of parents can be useful in accumulating the genes for Striga
resistance mechanisms in progenies.
The F2 populations derived from crosses between Striga-resistant x susceptible genotypes
were evaluated in Striga infested benches in 2008 and 2009. The segregation patterns
suggest that single dominant genes govern Striga resistance. The test for allelism showed
that two non-allelic genes were responsible for the resistance to S. gesnerioides in cowpea.
A new Striga resistance gene seems to be involved in genotype KVx771-10 resistance to S.
gesnerioides, which confers resistance to all studied Striga races. Gene 994-Rsg in
genotype IT81D-994 which confers Striga resistance to SR 1 and gene Rsg 3 also
conferring Striga resistance to SR 1 segregated differently for the resistance to SR 5
suggesting that they were different but both confer resistance to SR 5.

The main goals of this study were to ascertain farmers' preferred traits in rice landraces and their perception of Rice yellow mottle virus, to collect rice landraces across Burkina Faso, investigate their genetic diversity, and to exploit this diversity in a search for varieties resistant and tolerant to RYMV, for their utilisation in rice breeding. Farmers' preferred traits, approaches to crop management, and disease perceptions were assessed using a Participatory Research Appraisal (PRA) approach. In the main rice growing regions of Burkina Faso, 330 rice landraces were collected. The agro-morphological diversity of the germplasms was evaluated in the field with 20 quantitative and 30 qualitative agro-morphological parameters. Thereafter, 22 Simple Sequence Repeat molecular markers were used to assess the genetic diversity and the population structure of the collection. Finally, the rice landraces were screened against four RYMV isolates to assess the susceptibility, tolerance and resistance of the landraces in the collection using visual assessment and Enzyme Linked Immunosorbent Assay. The PRA identified sweet taste, grain expansion when cooking, easy cooking and yield as paramount selection criteria in rural rice farming communities in Burkina Faso. Drought and disease resistance are characters that farmers wish to have in their varieties. The PRA also highlighted that farmers are conscious of RYMV disease in their fields. However, they are unaware about the epidemiology of the disease.
An agro-morphological study of the phenotypic diversity of the collection confirmed the presence of the two cultivated rice species: O. glaberrima and O. sativa. There were more O. sativa accessions than O. glaberrima landraces. There were 48 O. glaberrima and 282 O. sativa accessions in the collection. Both species were divided into four clusters, reflecting the richness of the collection. The underlying genetic diversity of the collection was confirmed by the use of 22 Simple Sequence Repeat molecular markers. The neutral markers confirmed the existence of two substructures, namely O. glaberrima and O. sativa, and the presence of admixture varieties. However, a core collection of 52 individuals was developed. This included 13 O. glaberrima and 39 O. sativa accessions. It reflects the genetic diversity of the sub-clusters present in each species. This core collection contains 89% of the allelic richness of the collection. Its small size will facilitate the maintenance and active use of diversity of germplasm in the core collection. The entire collection was utilised to search for varieties resistant and tolerant to RYMV disease. The screening of the collection with different RYMV isolates exposed the susceptibility of most of the accessions in the collection. Most of the O. sativa indica accessions were highly susceptible. However, ten O. glaberrima accessions displayed a delay of symptom expression, and moderate resistance. However, their resistance was overcome later by a particularly virulent RYMV isolate BF1. Remarkably, a single moderately resistant cultivar, BM24, showed that partial resistance and tolerance to RYMV can be found in an O. sativa variety. Serological evaluation of this local variety in comparison with the partially resistant variety, Azucena, showed that BM24 and Azucena expressed similar resistance patterns. A genetic profile of both varieties showed that both had an identical allele status at RM101, which is a marker bracketed in the same zone as the QTL12.Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.

AbstractIn June 2015, four multi-stakeholder platforms (Sanguie, Zondoma, Soum, and Association Yiye) were established in different regions of Burkina Faso to promote agricultural activities. By 2018, more than 200 farmers had already been trained on different aspects of the cowpea value chain including grain production, storage, and food processing skills. The platforms played a key role in the dissemination of new cowpea varieties through demonstrations, field days, the mass media, and social media. About 160 demonstrations were established by the members of the platforms every year from 2015 to 2018. Each platform was supported to produce 10 ha of certified seeds making a total of 40 ha each year and 160 ha during the four-year period. Due to the demand for foundation seeds that was increasing year after year in Burkina Faso and the inability of INERA to produce enough seeds, the most successful platform members were contracted by the INERA Seed Unit to produce foundation seeds in order to meet the high demand in the country for certified seed production. Although there are no official statistics about certified seeds produced in Burkina Faso in terms of demand, recent happenings have shown their increased production. For instance, in 2018 about 1000 tons of certified seeds were produced compared to previous years which had less than 700 tons.

AbstractAccess to seeds of improved groundnut varieties is the most critical problem of farmers in Burkina Faso. Firstly, majority do not know the existence of improved varieties and secondly the price is not affordable to them. Based on the above, the INERA groundnut breeders’ team established four innovation platforms on groundnut in the Region of Centre-East, Region of Centre-North, Region of Centre-West and Region de la Boucle of Mouhoun. Through these platforms, Quality Declared Seeds (QDS) were produced for the first time in Burkina Faso in 2016 with support from the Tropical Legumes phase III (TL III) project. Since then, QDS and certified seeds are produced and sold to the local communities at affordable small packs in order to make improved seeds accessible to the poor farmers. So far about 10,000 persons have been reached with small packs. Farmers, agricultural extension and NGO staff have been trained in groundnut seed production, demonstrations, field days and Farmer Participatory Variety Selection (FPVS) to promote the improved varieties and the best agronomic practices. Farmers’ yields increased from 500–700 kg/ha to 1200–1500 kg/ha increasing women and youth incomes from 200 USD to 800 USD/year only for those who grow groundnut during the rainy season. Those who grow during rainy and off-seasons their incomes can reach 1200–1500 USD. Links with financial institutions have facilitated access to credit for these farmers. In the future, the Platform sustainability will be assured through members’ annual financial contributions and strong production contracts among traders, processors and farmers.

Full textAbstract:
AbstractThe Bill and Melinda Gates Foundation (BMGF) funded Tropical Legumes (TL III) project was implemented in seven sub-Saharan Africa countries (Burkina Faso, Ghana, Mali, Nigeria, Ethiopia, Tanzania, and Uganda) and South Asia (India). Shortage of seed of improved varieties has been identified as the greatest hindrance to farmer adoption of new agricultural technologies developed through this project. This chapter compares the different approaches followed by different countries in the establishment of Multi-Stakeholder Platforms (MSPs) for supply of improved legume seed to farmers. Achievements from this initiative are mixed and multi-dimensional. The details herein provide the reader with insights on the level of success of innovation platforms in the different countries and implications for agricultural technology dissemination to smallholder farmers. Key achievements include strengthened linkages among various legume seed value chain actors, participation of several cadres of seed producers in a decentralized system resulting into significant increase in the production of certified and quality declared seed of legumes, and rapid adoption and use of newly released varieties by smallholder farmers. As for those areas where the initiative did not produce the desired results, it is a testament that unless a well thought-out inclusive and comprehensive approach which defines the critical roles of each player in the value chain is developed, current seed shortages will continue, eroding emerging market opportunities and good intentions of development partners. The reader is directed to individual chapters for details of the process followed by each country/crop in the establishment of MSPs, their composition, key achievements, challenges, and lessons for overall improvement of the national legume seed systems.
