| The durum wheat collection maintained at the Spanish Centre for Plant Genetic Resources (CRF) holds about 1,100 durum wheat (Triticum turgidum L.) accessions, mostly local cultivars and landraces. A set of 200 Spanish entries from nine agro-ecological zones, representative of the geographic and genetic diversity of the domain of the Spanish core collection, were selected and grown in a field experiment in 2007. The set involved ssp. dicoccon, ssp. durum and ssp. turgidum. Cultivars ¡®Don Pedro¡¯, ¡®Vitr?®n¡¯ and ¡®Simeto¡¯ were included as checks. Quality determinations consisted on protein content, gluten strength, ?Â-carotene, test weight, vitreousness and the European quality index (QI) for durum wheat. The best quality in global terms was reached by the ssp. durum, mostly due to its greater vitreousness, gluten strength and ?Â-carotene content. A geographical pattern significantly explained differences in the quality of the accessions collected in the studied agro-ecological zones since quality increased from northern to southern entries. The trait that mostly affected the QI was gluten strength, which accounted for 84% of variations in QI. The high protein content, gluten strength and ?Â-carotene content of some accessions suggest their usefulness as sources of genes for durum wheat quality improvement. | |
