The seed germination test is generally used to assess the seeds germination quality. The objective of this study was to determine the germination kinetics as well as the diversity of pepper accessions (Capsicum annuum L.) from the Diffa, region of Niger according to the germination potential. These accessions were collected in 5 Departments of the Diffa region in 2020 and 2022. Thus, the emergence of the seedlings was carried out in vitro according to a device in complete randomized blocks with three (3) repetitions. The analysis of variance (ANOVA) showed a significant difference between the accessions, for all the parameters analyzed (P˂0.000). The average germination rate which varied from 7.33% for N’guigmi (Ng-047) to 100% for Bosso accessions. Strong correlations were observed between germination rate and germination rate (0.63). The ascending hierarchical classification (HAC) and the principal component analysis (PCA) revealed a structuring of the accessions into 3 main distinct groups. The G1 group composed of 27 accessions is characterized by a long germination time and a germination time of 50% and by a high germination rate. Group G2 is made up of 10 accessions with a long latency time and 50% germination time. As for the G3 group, it is also made up of 10 accessions with a high germination time and latency time. This study will allow breeders to have a biological base material for further research.

The seed germination test is generally used to assess the seeds germination quality. The objective of this study was to determine the germination kinetics as well as the diversity of pepper accessions (Capsicum annuum L.) from the Diffa, region of Niger according to the germination potential. These accessions were collected in 5 Departments of the Diffa region in 2020 and 2022. Thus, the emergence of the seedlings was carried out in vitro according to a device in complete randomized blocks with three (3) repetitions.

Abstract: (french)
Le test de germination des semences permet généralement d’évaluer la qualité germinative des graines. La présente étude avait pour objectif de déterminer la cinétique germinative ainsi que la diversité des accessions de poivron (Capsicum annuum L.) de la région de Diffa au Niger en fonction du potentiel de germination. Ces accessions ont été collectées dans 5 Départements de la région de Diffa en 2020 et 2022. Ainsi l’émergence des plantules a été effectuée in vitro selon un dispositif en blocs complets randomisés avec trois (3) répétitions. L’analyse de la variance (ANOVA) a montré une différence significative entre les accessions, pour tous les paramètres analysés (P˂0,000). Le taux moyen de germination qui a varié de 7,33 % pour N’guigmi (Ng-047) à 100% pour les accessions de Bosso. Des corrélations fortes ont été observées entre le taux de germination et la vitesse de germination (0,63). La classification ascendante hiérarchique (CAH) et l’analyse en composante principale (ACP) ont révélé une structuration des accessions en 3 principaux groupes distincts. Le groupe G1 composé de 27 accessions est caractérisé par une durée de germination et par un taux de germination élevés. Le groupe G2 est constitué de 10 accessions ayant un temps de latence et une durée de 50% germination longs. Quant au groupe G3 il est également constitué de 10 accessions avec une durée de germination. Cette étude permettra aux sélectionneurs d’avoir un matériel de base biologique pour la poursuite de la recherche.
