“…The results of analyses highlighted a high variability within the studied varieties at the qualitative and quantitative levels. Indeed, the high values of the coefficient of variation for several characters and the number of modalities per qualitative character would indicate a high heterogeneity within the studied material (Boyé et al 2016). This heterogeneity between varieties is apparent in the principal component analysis with its two components to reflect the diversity within cowpea varieties.…”

“…The number of seeds per pod, ranging from 14 to 59 seeds, is higher than that obtained by Egbadzor et al (2014), which varied from 9 to 21 seeds. According to Boyé et al (2016), the variability observed within varieties concerning the number of seeds per pod reflects their ability to mobilize assimilates to reserve structures. Concerning the weight of 100 seeds, Khan et al (2010) showed that the variability obtained between varieties depends on genotype and climatic factors.…”

Vegetable Cowpea (Vigna unguiculata) is one of the neglected legumes in Burkina Faso, and as a result, its genetic diversity remains poorly known. The main aim of this study was to know its genetic variability through an agro-morphological characterization. Twenty vegetable cowpea varieties were evaluated at the Kamboinsé Environmental, Agricultural and Training Research Center following a three-replication Fischer block design under rainfed conditions. Fifteen quantitative and nine qualitative variables were collected and subjected to various statistical analyses. Analysis of variance was significant for the variables 50% flowering, vegetable cowpea date, number of pods obtained per plant, number of seeds per pod, fresh pod weight, fresh pod yield, pod length, plant height, seed length and chlorophyll content. Strong correlations were also reported between the various variables. The observed diversity is structured in three morphological groups viz., Group 1 consists of individuals with early flowering, high chlorophyll content and the number of pods obtained per plant. Group 2 brings together the varieties of average agronomic performance for pod length, the number of pods per plant, number of days at 95% maturity, fresh pod weight, yield of fresh pods and group 3 of varieties with long pods, early green date, high pod weight and good fresh pod yield. Among the tested varieties, the varieties IT83S-872 (30 pods), IT84S-2246 (27 pods), Baguette (25 pods), IT83S-818 (26 pods), and IT85F-2682 (24 pods) stood out for their high pod production. In addition, the varieties of vegetable cowpea baguette, baguette grimpant, Telma, and IT83S-911 showed the best performance in terms of early vegetable cowpea date stage, longest pods, highest pod weight and best yield of fresh pods. The high genetic variability level within the tested varieties could be exploited in future green cowpea breeding programmes.

1 RESUME L’objectif de l’étude est d’identifier les variétés de maïs ayant des caractères agronomiques intéressants en milieu paysan. Le matériel végétal est composé de quatre variétés améliorées, IVDT, 2009TZEE-W-STR, 2009TZE-DT STR, CMS8704 et du témoin. L’essai est conduit avec quatre variétés et un témoin local selon un dispositif expérimental en blocs de Fischer à quatre répétitions. La variété IVDT a un cycle de culture de 75 jours, les variétés 2009TZEE-W-STR et 2009TZE-DT-STR ont un cycle de 95 jours et la variété CMS8704 a un cycle de 110 jours. Les taux de résistance à la verse sont respectivement de 89,04%, 89,92%, 85,82%, 63,73% et de 62,47% pour les variétés IVDT, 2009TZEE-W-STR, 2009TZE-DT-STR, témoin local et CMS8704. Le faible nombre de grains par épi est observé sur la variété CMS8704 (229,69 ± 30,28) suivie du témoin local (290, 84 ± 28,27). Le meilleur nombre de grains de maïs par épi est obtenu sur les variétés 2009TZEE-W-STR (337,85 ± 39,44) et 2009TZE-DT-STR (361,60 ± 30,14). La variété CMS8704 (0,17 kg ± 0,01) a enregistré le faible poids de grains suivie du témoin local (0,194 kg ± 0,01). Le poids élevé de grains est obtenu sur les variétés 2009TZEE-W-STR (0,29 kg ± 0,02) et 2009TZE-DT-STR (0,30 kg ± 0,02). Le faible rendement en grains est obtenu sur la variété CMS8704 (1,48 t ha-1 ± 0,27) suivie du témoin local (2,04 t ha-1 ± 0,20). Le meilleur rendement en grains est enregistré sur la variété 2009TZEE-W-STR (3,10 t ha-1 ± 0,32) suivie de 2009TZE-DT-STR (3,09 t ha-1 ± 0,15). Les variétés 2009TZEE-W-STR et 2009TZE-DT-STR sont plus performantes et présentent une bonne résistance à la verse dans les conditions de l’expérimentation. L’identification des variétés performantes permettra d’augmenter la productivité du maïs chez les producteurs à faible niveau d’intensification. ABSTRACT The objective of this study is to identify the varieties of corn having interesting agronomic characters in the farmers environment. The studied plant material is composed of four improved varieties, IVDT, 2009TZEE-W-STR, 2009TZE-DT STR, CMS8704 and the control. The study was done with four corn varieties and a local control according to an experimental device of Fischer blocks to four repetitions. The IVDT variety had a 75 day crop cycle, the varieties 2009TZEE-W-STR and 2009TZE-DT-STR have a cycle of 95 days and the CMS8704 variety has a cycle of 110 days. The percentage of lodging resistance are respectively of 89.04%, 89.92%, 85.82%, 63.73% and of 62.47% for the IVDT varieties, 2009TZEE-W-STR, 2009TZE-DT-STR, local witness and CMS8704. The weak number of grains per ear is observed on the CMS8704 variety (229.69 ± 30.28) consistent of the local control (290.84 ± 28.27). The best number of grains of corn per ear is gotten on the varieties 2009TZEE-W-STR (337.85 ± 39.44) and 2009TZE-DT-STR (361.60 ± 30.14). The CMS8704 variety (0.17 kg ± 0.01) recorded the weak weight of grains followed of the local witness (0.194 kg ± 0.01). The weight raised of grains is gotten on the varieties 2009TZEE-W-STR (0.29 kg ± 0.02) and 2009TZE-DT-STR (0.30 kg ± 0.02). The low number of kernels per ear was observed on the CMS8704 variety (229.69 ± 30.28) followed by the local control (290.84 ± 28.27). The best number of corn kernels per ear is obtained on the varieties 2009TZEE-W-STR (337.85 ± 39.44) and 2009TZE-DT-STR (361,60 ± 30,14). The CMS8704 variety (0.17 kg ± 0.01) recorded the low grain weight followed by the local control (0.194 kg ± 0.01). The high weight of grain is obtained on the varieties 2009TZEE-W-STR (0.29 kg ± 0.02) and 2009TZE-DT-STR (0.30 kg ± 0.02). The low grain yield was obtained on the CMS8704 variety (1.48 t ha-1 ± 0.27) followed by the local control (2.04 t ha-1 ± 0.20). The best grain yield is recorded on 2009TZEE-W-STR (3.10 t ha-1 ± 0.32) followed by 2009TZE-DT-STR (3.09 t ha-1 ± 0.15). The varieties 2009TZEE-W-STR and 2009TZE-DT-STR are more efficient and have good resistance to lodging in the conditions of the experiment. The identification of successful varieties will increase maize productivity in low-intensification producers.
