Cytological and agronomic characteristics of a F2 population from Triticum aestivum L. x T. durum Desf. hybrids were analyzed plant by plant. Means of morphologic traits in the F2 population were similar to those of the low-value parent. On average, F2 hybrids had 36.54 chromosomes per plant, indicating that each gamete lost 2.73 chromosomes at meiosis of the F1 generation. More than half of pl...

INTRODUCTION This study was undertaken with the objectives of formulating composite bread by utilising finger millet flour and foxtail millet flour and further to evaluate these breads for sensory, nutritional qualities, and glycemic response. METHODS Two genotypes of finger millet VL-146 and PRM-601 and one local cultivar of foxtail millet were studied. The finger millet flour (FMF) and foxt...

Historical Although the wheat plant (Triticum) is nowhere found in the wild state, it has been cultivated for human food from the earliest times of which we have record. The origin is held to have been in south-west Asia, in Mesopotamia. When Abraham (about 2000 B.C.) was visited by three angels unawares, he commanded Sarah to ‘make ready quickly three measures of fine meal, knead it, and make ...

Dough rheological and starch pasting properties play an important role in determining processing quality in bread wheat (Triticum aestivum L.). In the present study, a recombinant inbred line (RIL) population derived from a Gaocheng 8901/Zhoumai 16 cross grown in three environments was used to identify quantitative trait loci (QTLs) for dough rheological and starch pasting properties evaluated ...

The rheological behavior and functional properties of doughs from bambara-wheat composite flour was investigated. Bambara-wheat composite flour was prepared by substituting wheat with 0%, 10%, 15%, and 20% of bambara flour. The rheological behavior of their dough was analyzed with Mixolab. Breads produced from the flour were analyzed for physical characteristics. Organoleptic analysis was carri...

High Cd content in durum wheat (Triticum turgidum L. var durum) grain grown in the United States and Canada presents potential health and economic problems for consumers and growers. In an effort to understand the biological processes that result in excess Cd accumulation, root Cd uptake and xylem translocation to shoots in seedlings of bread wheat (Triticum aestivum L.) and durum wheat cultiva...

Wheat bran offers health benefits as a baking ingredient, but is detrimental to bread textural quality. Dextran production by microbial fermentation improves sourdough bread volume and freshness, but extensive acid production during fermentation may negate this effect. Enzymatic production of dextran in wheat bran was tested to determine if dextran-containing bran could be used in baking withou...

Improvement in activation of Rubisco by Rubisco activase can potentially enhance CO2 assimilation and photosynthetic efficiency in plants. The three homoeologous copies of TaRca2-α were identified on chromosomes 4AL, 4BS and 4DS (TaRca2-α-4AL, TaRca2-α-4BS, and TaRca2-α-4DS) in bread wheat. Expression patterns of the three copies at heading (Z55), anthesis (Z67) and grain-filling (Z73) stages w...

We report the results of a study on the effectiveness of Cot filtration (CF) in the characterization of the gene space of bread wheat (Triticum aestivum L.), a large genome species (1C = 16,700 Mb) of tremendous agronomic importance. Using published Cot data as a guide, 2 genomic libraries for hexaploid wheat were constructed from the single-stranded DNA collected at Cot values > 1188 and 1639 ...

Yellow rust (stripe rust), caused by Puccinia striiformis f. sp. tritici, is one of the most destructive foliar diseases of wheat in Egypt and worldwide. In order to identify wheat genotypes resistant to yellow rust and develop molecular markers associated with the resistance, fifty F8 recombinant inbred lines (RILs) derived from a cross between resistant and susceptible bread wheat landraces w...
