Ziel unserer Studie ist es, die Sortenvielfalt von Weizen hinsichtlich der Produktion und der Anpassungsfähigkeit zu untersuchen. Daher wurde in der Wilaya Tlemcen eine Bestandsaufnahme durchgeführt, um lokale und eingeführte Sorten von Hartweizen (Triticum durum) und Weichweizen (Triticum aestivum) im Hinblick auf ihre morphologische Charakterisierung zu sammeln. In diesem Zusammenhang wurde eine Sammlung von 16 Weizensorten aus verschiedenen Regionen der Wilaya Tlemcen anhand von 9 quantitativen agromorphologischen Merkmalen und 16 qualitativen Merkmalen untersucht. Die phänotypische Vielfalt wurde anhand des Shannon-Weaver-Diversitätsindex (H') auf verschiedenen Ebenen bestimmt (Gesamtheit der Stichprobe, nach Weizentypologie und nach Sortenbezeichnung). Die geschätzten H'-Werte zeigten eine gro e phänotypische Variabilität bei den verschiedenen quantitativen Merkmalen mit einem durchschnittlichen H' von 0,58 für Hartweizen und 0,52 für Weichweizen. Bei den qualitativen Merkmalen betrug der Diversitätsindex 0,05 für Hartweizen und 0 für Weichweizen. Die Ergebnisse der Hauptkomponentenanalyse (PCA) und der hierarchischen Klassifizierung (CAH) der untersuchten Population zeigten eine deutliche Unterscheidung zwischen den verschiedenen Sorten.
