Features and type of action of the main physical and chemical mutagens are considered: Marker regression analysis showed a strong association between all traits studied and a favourable allele originating from AUS located on the long arm of chromosome 4B. Agrobacterium-mediated transformation of wheat is becoming a viable alternative to the more established biolistic protocols. This study aimed at understanding the effect of additional ingredients baker’s yeast, macerated pears, grape must, honey, or water from macerated pears on the microbiota and biochemical characteristics of durum wheat -based sourdough. Moench germplasm from Ethiopia and Eritrea: Results obtained in a two-years field experiment study suggest low molecular weight glutenins LMW-GS as the fraction particularly inducible regardless of the N-form. CRM resulted always close to optimum value, EF in every case scored positive value, the value of index r2 was good, although in some cases values lower than 0. Unfortunately, the comprehension of the mechanisms implicated in salinity stress alleviation by AM symbiosis is far from being complete.

In the low rainfall site of Grosseto, most of the grain yield originated from dry matter accumulation, while in the wetter environment of Arezzo remobilization and accumulation contributed equally to grain yield. In view of the economic importance of durum wheat in Italy and in the Mediterranean and Near East Region much effort was devoted to its genetic improvement. The PRP region was demonstrated to be present as a single or double copy in the common wheat haploid genome. Real-time PCR analysis showed that only DNA of wheat was amplified and no amplification product was observed for phylogenetically related cereals, indicating that the PRP detection system is specific to wheat. We found three cases in which putative QTL for agronomic traits overlapped marker trait association. Studies on productivity lodge resistance of radiation induced mutants of syrian local durum wheat.

This is certainly relevant because the most of drought or salinity studies performed on cereal seedlings have been done in growth chambers under controlled culture conditions and artificial lighting set at low light. This investigation presents a breeding program for induction and development of a new genotype of durum wheatresistant to lodging with high yield, by irradiation durum wheat hybrids F2 with gamma rays Gy, during cultivation seasons.

Fibres can disrupt the starch-protein matrix of the dough during pasta preparation and can also often swell more readily with water than starch, competing with the starch for water during dough development. Finally, transcriptional analyses showed similar expression levels in roots and leaves of durum wheat seedlings. In the F 2 generation from crosses semi-dwarf – I with medium – S with semi-dwarf – I, a phenotypic dihybred segregation 9: Mycosphaerella graminicola Fuckel J.

High Cd content in durum wheat Triticum turgidum L. Experimental design used was simple lattice.

Full Text Available Abstract Background High amylose starch has attracted particular interest because of its correlation with the amount of Resistant Starch RS in food. Average yield reduction was as high as and kg ha-1 for every increment in disease severity on a scale in both seasons, respectively.

Durum wheat Triticum turgidum L. Farak and Jordao cultivars and Triticum durum Desf. Quinoa seeds may represent an excellent source of natural antioxidant compounds and, in particular, of the free-soluble antioxidant fraction.

Geographical patterns of morphological variation in comppet Sorghum bicolor L. In vivo examination of wheat seed germination, plant height, phenolic compounds, chlorophyll, and carotenoid contents proved the efficiency of the bacterial cells and the secreted antagonist activities to protect Tunisian durum wheat Triticum turgidum L.

Kernel texture is a major determinant fi,m end-use quality of wheat.

Interestingly, the expression in leaves is significantly induced following salinity stress, suggesting a potential role of TdPP1a in wheat salt stress response. Three winter durum wheat cultivars originating from Austria, Slovakia, and Poland were analyzed during seasons for FHB incidence and Fusarium mycotoxin accumulation in harvested grain. Qualitative traits and metabolite evaluation by gas chromatography linked to mass spectrometry were carried out on immature 14 days after flowering and mature seeds.

In practical application these result enable plant breeders, seed producers and variety testers fjlm determine wheat varieties easily sinse it is method for morphological systematics of wheat. Combined treatments were found to be more efficient than the sum of effects of the single treatments. Fusarium head blight FHB is considered as one of the most damaging diseases, resulting in yield and quality reduction as well as contamination of grain with mycotoxins.

A historical series complte Tunisian durum wheat accessionsderived from three crop years, was used to compare the amount of CM3 vomplet landraces to advanced cultivars. In the field study, a mixture of the two strains was applied to durum wheat cilm weekly from heading until anthesis and ii at flowering, compared to untreated and fungicide treated plots.

Soft durum wheat – a paradigm shift. However, plants exposed to multiple stresses at the same time, a combinatorial approach reflecting real-world scenarios, show tailored responses completely different from the response to the individual stresses, due to the stress-related plasticity of plant genome and to specific metabolic modifications.

Durum wheat grain protein functionality can be influenced by N fertilization, particularly in the varieties of relatively with less gluten strength [9]. Full Text Available Durum wheat quality is a complex system that combines yield characteristics, cultivation conditions and certification requirements.

It was a pot experiment with 6 treatments 2 cultivars with 3 saids field time exposure. Parallel analysis of the flag leaf transcriptome under stress uncovered global trends of early changes in regulatory pathways, reconfiguration of primary and secondary metabolism and lowered expression of transcripts in photosynthesis in all three lines.

Cluster analysis was divided 36 lines into three groups. From these M2, 17 desirable putative mutant plants which varied significantly with the mother were visually selected.

RIL lost less cilm and showed constitutively higher stomatal conductance, photosynthesis, transpiration, abscisic acid content and enhanced osmotic adjustment at equivalent leaf water compared to parents, thus defining a physiological strategy for high yield fil under water stress. Radiation and chemically induced mutations have provided variability in selection for novel varieties.

Wheat kernel texture dictates U. Two durum -rye translocation lines were obtained following irradiation. The results show that durum wheat was more sensitive to both Zn deficiency and Cd toxicity as compared to bread wheat. All mutants showed resistance to lodging and there was a significant reduction in plant height.

Irradiated seeds were grown as M1 population along with parental variety as control at Almuzahmiah Research Station of Riyadh, Saudi Arabia.

Conversely, at Grosseto grain N content relied most on remobilization and at Arezzo remobilization and accumulation contributed equally.
