During the 1940s and 1950s different barley landrace recollections were carried out all over the Spanish territory, and some germplasm collections were constituted in different Research Institutes. Among these the one preserved at the Aula Dei Experimental Station was quite relevant. During the 1980s most of these collections were incorporated into the emerging National Germplasm Bank, creating in such a way a truly National Spanish Barley Collection.
In those days, some research groups in Spain started to make a preliminary field evaluation of the National Collection, with the aim of incorporating autochthonous material into our barley breeding programs.
This effort was hampered by the very large number of entries constituting the collection (over 2000), which prevented a good agronomic evaluation of the material. Therefore, the effective use of the very interesting diversity that was present in this collection was not efficient.
Under such circumstances we decided the constitution of the Spanish Barley Core Collection. This core collection should have a manageable size, still including a good representation of the variability that was present in the National Collection. It was carried out in a systematic manner, based on the passport data, and on the preliminary results that we have developed in previous agronomic evaluations. Immediately after the constitution of the collection, we undertook an exhaustive evaluation of the material, with a double objective, to offer an important tool for breeding purposes, and to provide barley scientists with an information-rich resource for scientific studies.
This decision was taken by the three groups involved, at that moment, in the National Barley Breeding Program, and with the help and financial support of the Centro Nacional de Recursos Fitogenéticos and the Instituto National de Investigaciones Agrarias, the work was finally completed.
This Web is offering the results derived from such effort.

The Core Collection was finally constituted with 159 inbred lines derived from Spanish landraces, and 16 varieties widely growth in Spain in the second half of the 20th century.
The base collection is located at the Centro Nacional de Recursos Fitogenéticos (La Canaleja, Alcalá de Henares), with a duplicate at the Aula Dei Experimental Station Germplasm Bank (Zaragoza).
The active collection is maintained by the Barley Genetics and Breeding Group at the Aula Dei Experimental Station (CSIC) in Zaragoza, under the responsibility of Prof. José M. Lasa.
Sample demands will be attended from Zaragoza.
Levels of information:
The constitution and evaluation of the Spanish Barley Core Collection is the result of the joint effort of three Spanish research groups from the Estación Experimental de Aula Dei-CSIC from Zaragoza, the IRTA from Lleida and the ITA from Valladolid with the collaboration of the Centro Nacional de Recursos Filogenéticos.
The group from the Estación Experimental de Aula Dei, under the direction of Prof. J.M. Lasa, has been constituted by Drs. A. Casas, P. Gracia, E. Igartua, S. Yahiaoui and Mrs. B. Medina.
The group from IRTA, under the direction of Dr. J.L. Molina, has been constituted by Prof. I. Romagosa, Dr. M. Moralejo and Mrs. A. López.
The group from ITA, under the direction of Mr. J.L. Montoya, has been constituted by Dr. F. Ciudad and Mrs. P. Codesal.
The evaluation of disease resistances has been carried out at the Institute of Epidemiology and Resistance Resources from the Federal Centre for Breeding Research on Cultivated Plants, Aschersleben, Germany, under the direction of Prof. PD Dr. F. Ordon.
The evaluation of Rhynchosporium secalis resistance has been carried out at the Bayerische Landesanstalt für Landwirtschaft, Freising. Germany under the direction of Dr. G. Schweizer.
