Abstract
The genus Aegilops includes about 20 identified species. At present, it is more and more accepted the idea that different Aegilops, as relatives of wheat, can serve as suitable materials in wheat genetic improvement. This is very important, especially in creating wheat lines or cultivars with high resistance to abiotic stresses and diseases. Researchers of the DPST, for several years continue the ex situ and laboratory evaluations on 24 Aegilops accessions collected in different areas of Albania, in order to evidentate some of their most interesting morpho physiological parameters. The ear weight, seed number, seed weight per ear and 1000 seeds weight for each Aegilops accession included in the experiment, have been evaluated. Beside these, the seeds imbibition potential and seedlings weight, height, leaf area have been evaluated, too. From the results of the numerous data processing, it is concluded that among the Aegilops accessions, included in the study, exist significant differences related their seeds and seedlings biometric parameters. For the most part of the evaluated parameters, the conical ear Aegilops accessions show advantages toward the cylindrical ones. Correlative analysis resulted in significant differences in the coefficients of correlation between seeds and seedlings parameters produced by Aegilops with distinct forms of the ear, respectively conical and cylindrical ones.
Keywords: Aegilops, conical/ cylindrical ear, correlations, imbibition.
