Paperback. Condition: new. Paperback. The objective of our study is to examine wheat varietal diversity in terms of production and adaptation. An inventory was therefore conducted in the Wilaya of Tlemcen to collect local and introduced varieties of durum wheat (Triticum durum) and soft wheat (Triticum aestivum) for morphological characterization. In this context, a collection of 16 wheat varieties from different regions within the Tlemcen Wilaya was studied using 9 quantitative agromorphological traits and 16 qualitative traits. Phenotypic diversity was determined using the Shannon-Weaver diversity index (H') at different levels (entire sample, by wheat type, and by variety name). The estimated H' values showed wide phenotypic variability for the various quantitative traits, with an average H' of 0.58 for durum wheat and 0.52 for soft wheat. For the qualitative traits, the diversity index was 0.05 for durum wheat and 0 for soft wheat. The results of the principal component analysis (PCA) and hierarchical classification (CAH) of the studied population showed a clear distinction between the different varieties.

Para tal, foi realizado um inventario na provincia de Tlemcen com o intuito de recolher variedades locais e introduzidas de trigo duro (Triticum durum) e de trigo mole (Triticum aestivum), com vista a sua caracterizacao morfologica. Neste contexto, foi estudada uma colecao de 16 variedades de trigo provenientes de diferentes regioes da provincia de Tlemcen, utilizando 9 caracteristicas agromorfologicas quantitativas e 16 caracteristicas qualitativas. A diversidade fenotipica foi determinada pelo indice de diversidade de Shannon-Weaver (H') a diferentes niveis (totalidade da amostra, por tipologia de trigo e por nome varietal). Os valores estimados de H' revelaram uma ampla variabilidade fenotipica para as diferentes caracteristicas quantitativas, com um H' medio de 0,58 para o trigo duro e de 0,52 para o trigo mole. No que diz respeito as caracteristicas qualitativas, o indice de diversidade foi de 0,05 para o trigo duro e de 0 para o trigo mole. Os resultados da analise de componentes principais da populacao estudada (ACP) e da classificacao hierarquica (CAH) revelaram uma distincao clara entre as diferentes variedades.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Notre étude a pour objectif d'étudier la diversité variétale de blé sur le plan de production et sur le plan d'adaptation. Un inventaire a donc été effectué dans la wilaya de Tlemcen afin de collecter des variétés locales et introduites, de blé dur (Triticum durum), et de blé tendre (Triticum aestivum) en vue de leur caractérisation morphologique. Dans ce contexte, une collection de 16 variétés de blé de déférentes régions dans la Wilaya de Tlemcen a été étudiée en utilisant 09 traits agro-morphologiques quantitatifs et 16 traits qualitatifs. La diversité phénotypique a été déterminée par l'indice de diversité Shannon-Weaver (H') à différents niveaux (Totalité de l'échantillon, par typologie du blé et par nom variétal). Les H' estimés ont montré une large variabilité phénotypique pour les différents traits quantitatifs avec un H' moyen de 0,58 pour le blé dur et 0.52 pour le blé tendre. Concernant les traits qualitatifs, l'indice de diversité a été de 0,05 pour blé dur et 0 pour le blé tendre. Les résultats de l'analyse en composante principale de la population étudie (ACP) et de la classification hiérarchique (CAH) ont montré une nette distinction entre les différentes variétés. 92 pp. Französisch.…

Paperback. Condition: new. Paperback. Celem naszego badania jest analiza roznorodnosci odmian pszenicy pod katem produkcji i przystosowania. W zwiazku z tym przeprowadzono inwentaryzacje w prowincji Tlemcen w celu zebrania lokalnych i wprowadzonych odmian pszenicy twardej (Triticum durum) oraz pszenicy miekkiej (Triticum aestivum) w celu ich charakterystyki morfologicznej. W tym kontekscie zbadano kolekcje 16 odmian pszenicy pochodzacych z roznych regionow prowincji Tlemcen, wykorzystujac 9 ilosciowych cech agromorfologicznych oraz 16 cech jakosciowych. Roznorodnosc fenotypowa okreslono za pomoca wskaznika roznorodnosci Shannona-Weavera (H') na roznych poziomach (cala proba, wedlug typologii pszenicy oraz wedlug nazwy odmiany). Oszacowane wartosci H' wykazaly duza zmiennosc fenotypowa w przypadku poszczegolnych cech ilosciowych, przy sredniej wartosci H' wynoszacej 0,58 dla pszenicy twardej i 0,52 dla pszenicy miekkiej. W odniesieniu do cech jakosciowych wskaznik roznorodnosci wyniosl 0,05 dla pszenicy twardej i 0 dla pszenicy miekkiej. Wyniki analizy glownych skladowych badanej populacji (ACP) oraz klasyfikacji hierarchicznej (CAH) wykazaly wyrazne rozroznienie miedzy poszczegolnymi odmianami. This item is printed on demand.

Paperback. Condition: new. Paperback. Il nostro studio ha l'obiettivo di analizzare la diversita varietale del grano dal punto di vista della produzione e dell'adattamento. E stato quindi effettuato un inventario nella wilaya di Tlemcen al fine di raccogliere varieta locali e introdotte di grano duro (Triticum durum) e di grano tenero (Triticum aestivum) per la loro caratterizzazione morfologica. In questo contesto, e stata studiata una collezione di 16 varieta di grano provenienti da diverse regioni della Wilaya di Tlemcen, utilizzando 9 caratteri agromorfologici quantitativi e 16 caratteri qualitativi. La diversita fenotipica e stata determinata mediante l'indice di diversita di Shannon-Weaver (H') a diversi livelli (campione complessivo, per tipologia di grano e per nome varietale). I valori di H' stimati hanno evidenziato un'ampia variabilita fenotipica per i diversi caratteri quantitativi, con un H' medio pari a 0,58 per il grano duro e a 0,52 per il grano tenero. Per quanto riguarda i caratteri qualitativi, l'indice di diversita e risultato pari a 0,05 per il grano duro e a 0 per il grano tenero. I risultati dell'analisi delle componenti principali (ACP) della popolazione studiata e della classificazione gerarchica (CAH) hanno evidenziato una netta distinzione tra le diverse varieta.

Paperback. Condition: new. Paperback. Ziel unserer Studie ist es, die Sortenvielfalt von Weizen hinsichtlich der Produktion und der Anpassungsfaehigkeit zu untersuchen. Daher wurde in der Wilaya Tlemcen eine Bestandsaufnahme durchgefuehrt, um lokale und eingefuehrte 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 phaenotypische Vielfalt wurde anhand des Shannon-Weaver-Diversitaetsindex (H') auf verschiedenen Ebenen bestimmt (Gesamtheit der Stichprobe, nach Weizentypologie und nach Sortenbezeichnung). Die geschaetzten H'-Werte zeigten eine grosse phaenotypische Variabilitaet bei den verschiedenen quantitativen Merkmalen mit einem durchschnittlichen H' von 0,58 fuer Hartweizen und 0,52 fuer Weichweizen. Bei den qualitativen Merkmalen betrug der Diversitaetsindex 0,05 fuer Hartweizen und 0 fuer Weichweizen. Die Ergebnisse der Hauptkomponentenanalyse (PCA) und der hierarchischen Klassifizierung (CAH) der untersuchten Population zeigten eine deutliche Unterscheidung zwischen den verschiedenen Sorten.
