Chemotaxonomy of Wild Diploid Triticum L. (Poaceae) Species in Iran

This study evaluates the taxonomic status and the variation of wild diploid Triticum L. species using leaf flavonoid compounds in Iran. Two-dimensional maps of these species were provided using polyamide Thin Layer Chromatography. In order to show the taxonomic position of these species, the cluster analysis based on Euclidean Distance Coefficient and Ward Method and Factor analysis were applied (Principle Component Analysis). The flavnoid compounds purification of each accession and species was done. The results of cluster analysis showed that T. boeoticum subsp. boeoticum Boiss. and T. boeoticum subsp. thaoudar Reut. ex Boiss. are completely distinguished from each other. T. boeoticum subsp. thaoudar shows more similarity to T. urartu Tum. ex Gand., but T. boeoticum subsp. boeoticum displays affinity to T. monococcum L. The results of this study showed variability of flavnoid compounds at the diploid levels in Triticum species. Also flavnoid profiles can be mentioned as well marker to show the taxonomic position of these species.
