ResumenIn this study, allelic diversity for those genes was evaluated in a wide sample of genotypes, winter and spring, 2 and 6-row barleys, mainly from the Western Mediterranean region. It included 159 landraces from the Spanish Barley Core Collection (SBCC, Igartua et al ., 1998) and a set of 80 accessions (reference cultivars) mainly from other European countries. Specific alleles for VRN-H1 were found in the Iberian Peninsula, in a higher frequency than that seen in other materials. Allelic diversity matches with flowering time phenotypic responses across several series of field trials and controlled conditions experiments. The phenotypic differences apparently may entail adaptive responses. These results led us to initiate a marker-assisted selection program to introduce the vernalization genes of a Spanish accession into the French winter cultivar Plaisant.
