L’isolement mycologique a été effectué par la méthode « direct plating » et l’identification des espèces fongiques toxinogènes a été réalisée par des méthodes microscopiques et moléculaires. Un total de 220 échantillons collectés auprès des agriculteurs (n=144) et de points commerce (n=76) ont été analysés par la méthode multi-analyte par LC/ESI-MS/MS. La présente étude a pour principal objet de dresser un profil complet des différentes mycotoxines et des espèces fongiques toxinogènes se développant sur le millet perlé tunisien (Pennisetum glaucum (L) R.Br. It is recommended that efforts should be made to widen the current gene pool in Namibia. Lodging susceptibility, tillering attitude, spike density, fodder yield potential, early vigour, and spike shape were the phenotypic characters upon which some clusters were based in both datasets. UPGMA phenograms of 29 morphological characterized genotypes were generated for SSR and morphology data and the two trees revealed 78% resemblance. Ordination using Principal Coordinate Analysis (PCoA) on SSR data confirmed clusters generated by UPGMA for the 96Īccessions. A sample of 96 genotypes was further analyzed by SSR using Shannon-Wiener diversity index and revealed a value of 0.45 indicating low genetic diversity. A total of 1441 genotypes were collected from the National Gene Bank representing all the Namibian landraces.
This study aimed to understand the genetic diversity of the crop in Namibia by simple sequence repeats (SSRs) and morphology analysis. The crop suffers from undesirable production traits such as susceptibility to diseases, low yield, and prolonged reproductive cycle.
cultivars in Namibia have overall poor performance posing a threat to the nation’s food security because this crop is staple for over 70% of the Namibian population.
