Spanish landraces collection of durum wheat maintained at the CRF-INIA

Ruiz M., Martín I.

The tetraploid wheat collection maintained at the CRF-INIA holds 1,006 accessions. Within the subsp. turgidum, 428 entries are Spanish materials of the conv. durum (Desf) MK. and 126 are of the conv. turgidum. Accessions are stored in two types of collections, base and active, at -18 degrees and -4 degrees C, respectively, with a moisture content less than 7 per cent. These conservation conditions have shown to preserve adequately wheat germplasm. All the accessions at the CRF-INIA posses passport data about their origin, type of material, taxonomy, etc. A great part of the collection also have characterization data for different agro/mophological traits, including susceptibility to several diseases and molecular markers for gluten quality. Analysis of a group of 280 accessions have shown that Spanish landraces have, in general, intermediate growth habit, rough and large barbs, dense spikes, white and no pubescent glumes and white kernels.
