Abstract
Abstract: Aegilops ovata L.(Syn. Ae geniculata Roth.) an annual Grasse, relative to cultivated wheats, is distributed in north of Algeria. In order to understand the diversity of this species, morphological and biochemical characters were analyzed among fourteen populations sampled in different regions of Algeria. Principal Component Analysis using inflorescence characters allowed the separation of populations into six groups characterized by three main morphologic patterns correlated with the environmental conditions. The coastal and plain populations of humid and sub humid were characterized by the vigorous spikes, those of middle mountains of humid bioclimate and those of high mountains from semiarid bioclimate were distinguished by spikes more longer than those found in coastal and plain populations. Similar morphologic pattern were found in high mountains of humid bioclimate and in high steppic lands from semiarid conditions, the both were characterized by small spikes. Principal component analysis allowed the morphological spike parameters to be separated in two groups: thickness and length. Individuals were distinguished first through the spike width then the spike length, the rachis length and finally the awn number. The analyses of the high molecular weight subunits of glutenins showed a large variability associated with the bioclimatic conditions. This result would suggest that a part of glutenin variability was adaptive rather than neutral.
