Parental, F(1) , F (2) , BC (1) and BC (2) generations of four crosses involving four cultivars of durum wheat (Triticum durum Desf.) were evaluated at two sites in Tunisia. A three-parameter model was found inadequate for all cases except crosses Chili x Cocorit 71 at site Sidi Thabet and Inrat 69 x Karim at both sites. In most cases a digenic epistatic model was sufficient to explain variatio...

Wheat-derived foodstuffs represent about one-fifth of the calories consumed by humans worldwide. Bread wheat (Triticum aestivum L.) is one of the most important crops throughout the world, and it has been extensively studied for its allelopathic potential. In contrast, for allelopathy in durum wheat (Triticum turgidum ssp. durum), our knowledge is partial and fragmentary. Through highlighting r...

since the early 1980s (McMullen et al., 1997; Wilcoxson et al., 1988; Windels, 2000). Fusarium head blight (FHB), caused by Fusarium graminearum Management practices such as crop rotation have Schwabe, is a serious disease problem on durum wheat (Triticum been ineffective in limiting the disease. Most researchers turgidum L. var. durum ) in the USA. To date, the resistance to FHB available in h...

knowledge of traits associated with drought tolerance would be useful for developing breeding materials fortarget environments. to study these traits, 119 spring durum wheat breeding lines (bls) from the international maize and wheat improvement center (cimmyt) were evaluated along with local checks (one modern cultivar and three landraces) in three experiments under terminal and non-terminal d...

Ozone stomatal fluxes were modeled for a 3-year period following different approaches for a commercial variety of durum wheat (Triticum durum Desf. cv. Camacho) at the phenological stage of anthesis. All models performed in the same range, although not all of them afforded equally significant results. Nevertheless, all of them suggest that stomatal conductance would account for the main percent...

to evaluate durum pasta quality traits, using international standards, a study was conducted on seven improved and local durum wheat varieties. the traits examined included grain vitreousity (i.cc. no. 129), grain hardness index (h.i.), yellow berry (y.b.(, black point (h.p.), hectoliter weight (h.l.w.), thousand kerne! weight (t.k-w.j, protein percentage (i.cc. no. 105.1), protein quality ...

There are various types of discolouration that can affect common (Triticum aestivum L.) and durum [T. turgidum L. ssp. durum (Desf.) Husn.] wheat kernels grown on the Canadian Prairies. Black point and dark smudge, mostly associated with Alternaria alternata (Fr.) Keissl., and Cochliobolus sativus (Ito & Kurib.) Drechs. ex Dast. [anamorph Bipolaris sorokiniana (Sacc.) Shoemaker] are common disc...
