Genetic studies on tissue culture response and some agronomical traits in Egyptian bread wheat
The main effort of wheat breeder is the detection of genes and to merge them in a particular genotype using most suitable combination. Five Egyptian cultivars of bread wheat (_Triticum aestivum_ L.) were crossed in a half diallel mating design to produce 10 crosses. The genetic potential of embryogenic callus (EC%), plant regeneration (RGP%) response and its association with heading ... إقراء المزيد

Response of Bread Wheat Genotypes to Heat Stress

2013 | الكلمات المفتاحية Spring Wheat, Triticum aestivum L, High Temperature., Heat Stress,
Response of Bread Wheat Genotypes to Heat Stress
Fifty-eight spring wheat genotypes were evaluated for yield and yield component traits. These traits are Flag leaf area, plant height, heading to date, spikes per plant, 1000-kernel weight, and grain yield. This study evaluated wheat genotypes of diverse origins for three sowing date treatments during three seasons, to assess the heat stress tolerance of these genotypes under nine environmental conditions. ... إقراء المزيد

Combining ability and drought tolerance in bread wheat under water regimes. Egypt. J. plant. Breed
wenty eight genotypes (seven parents and their 21 F1 crosses) were evaluated for days to heading, spike length, 1000-grain weight, number of grains/spike and grain yield/plant under three water regimes (35, 65 and 100 % from the field capacity of the soil) over two years. Variance analysis revealed that all studied traits were significantly affected by soil moisture content. Moreover, ... إقراء المزيد

Screening of certain barley lines for resistance to root rot disease caused Fusarium graminearum. Archives of Phytopathology and Plant Protection

Screening of certain barley lines for resistance to root rot disease caused Fusarium graminearum. Archives of Phytopathology and Plant Protection
his investigation was conducted in 2005/2006 and 2006/2007 to test 235 barley lines plus two varieties Giza 127 and Giza 128 for resistance and susceptibility to Fusarium graminearum. All screened barley lines showed varied significant degrees of infestation to root rot pathogen. A screening system is described for identifying barley lines which are effective in controlling resistant or susceptible lines. ... إقراء المزيد

Stability of Wheat Genotypes under Different Environments and Their Evaluation under Sowing Dates and Nitrogen Fertilizer Levels
The current study aimed at assessing the heat tolerance of twelve wheatgenotypes under six environmental conditions (two locations and three years). Wheat genotypes were sown in two locations (Sohag and Assiut, Egypt) at two dates: November (favorable) and December (heat stress) during winter seasons of 2005/2006, 2006/2007 and 2007/2008. The combined analysis of variance showed that the flag leaf area, ... إقراء المزيد

This study carried out during the three successive seasons of 2004/2005, 2005/2006 and 2006/2007 at the Experimental Farm of Faculty of Agriculture, Sohag University, Egypt. Two durum wheat populations (_Triticum durum_ L.) in F3 generation of the crosses Chahba 88 x Bani-Swief 1 and Carcomun x Sohag 3 used in this investigation. One hundred F3 families underwent pedigree selection in ... إقراء المزيد

Increasing yield potential of promising bread wheat lines under drought stress
Fifty four spring wheat (Triticum aestivum L.) genotypes of diverse origin evaluated for four water irrigation treatments over two seasons. That evaluated 54 spring wheat promising lines for 4 potential competition traits, including plant height (PH), heading to date (HD), 1000-kernel weight (TKW), and grain yield (GY) for the ability of these genotypes to achieve high yields. Differences were found ... إقراء المزيد

Performance of Some Bread Wheat Genotypes under Different Irrigation Regimes and Nitrogen Fertilizer
Twenty four wheat genotypes (_Triticum aestivum_ L.), differ in yield performance were grown in a randomized complete block experimental design with three replications during two seasons 2004/2005 – 2005/2006 at Sohag University experimental Farm. The genotypes were evaluated under three water regimes (control treatment (I1), stress treatment (I2) and high stress treatment (I3)) and two nitrogen fertilizer levelS (70 Kg ... إقراء المزيد
