Abstract Fusarium head blight (FHB) is a disease caused by several Fusarium species, notably, F. culmorum and F. graminearum. These pathogens adversely affect the technological and sanitary qualities of cereal grains, particularly durum wheat. Under favorable environmental conditions and in susceptible varieties, these Fusarium species can significantly reduce both the quantity and quality of crops. This study evaluated the pathogenicity of the two Fusarium species (FC2006 and FG2008) in the growth of durum wheat coleoptiles. The plant material included four commercially grown parental varieties (G9, G10, G11, G12) and eight breeding lines (G1, G2, G3, G4, G5, G6, G7, G8).… More >

Abstract Blackpoint incidence was assessed on grain from six durum wheat (Triticum durum Desf.) varieties grown during crop season 2004-05 at four sites, in the traditional durum wheat growing region of Argentina. Broad differences in grain discolouration were detected among sites and varieties, together with significant variety x site interactions. Among varieties, those with lower thousand grain weight and higher widthto- length ratio (proportionally shorter grains) showed less susceptibility to this disease than heavy/large grain varieties. Differences among sites in the levels of blackpoint incidence were also related to the physical attributes of grains revealing the strong More >

Abstract The aims of this work were (1) the saturation of a linkage map of durum wheat using AFPLs and RAPDs, (2) mapping of QTL related to lipoxygenase activity and (3) estimation of its usefulness in marker-assisted selection to increase pasta colour. A mapping population of 83 recombinant lines (RILs) derived from the cross between durum wheat Kofa and UC1113 (Triticum turgidum L. var. durum) was evaluated for lipoxygenase activity during two growing seasons. It was used to generate a genetic map. Forty four AFLPs, 9 RAPDs, 2 isoenzymes and 1 storage protein were mapped onto a previous More >
