Lisboa: ISA, 2012http://hdl.handle.net/10400.5/4821Relatório de Bolsa de Integração na Investigação - Instituto Superior de AgronomiaWheat is one of the most important crops in the world and just last year the crop area of durum wheat in Portugal suffered a reduction of 69%, this way it becomes more important to characterize the Triticum durum commercial varieties available for crop production. In this work we used six durum wheat varieties usually planted in Portugal (Celta, Hélvio, Marialva, Don Duro, Saragolla and Severo), with the purpose of studying their genomic variability, using PCR-based molecular techniques. Our results indicate that, although being reproduced by self-fertilization, durum wheat’s varieties still show some genomic variability, not only among different varieties, but also between individuals from the same variety. We have also showed that, even though being commercial varieties, not all of them appear to have dough with superior end use quality. This variability can help us develop specific primers to easily distinguish different varieties, and aid in the identification and characterization of varieties with better quality traitsengwheatTriticum durumvarietiestetraploidgenomic variabilityreport
