Conventional wheat breeding programs aim at developing high yielding cultivars suitable for sowing under stress conditions and poor soils especially in newly reclaimed deserts. The objective of the current study was to develop high yielding and early maturing bread wheat (Triticum aestivum L.) lines adapted to grow in old and new reclaimed desert s...

... the basis of sequences of four wheat EST markers, PCR primer pairs were designed and used to screen the polymorphism among the studied lines. The primer sequences are shown in Table 1. PCR was carried out under the following conditions; one initial strand separation cycle at 94°C for 4 min followed by 32 cycles including a denaturation step at 94°C for 30 s, an annealing step at (50 to 60°C, depending on the primer sequence) for 30 s and polymerization step at 72°C for 1 min, with final extension step at 72°C for 5 min. ...

... lines Assiut-1, Assiut-2 and Assiut-3 gave grain yield significantly higher than that of the check variety. On the other hand, two inbred lines (that is Line 95 and Line 92) gave grain yield lower than that of the check variety at all the three As st-1 Asst-2 Asst-3 Line 95 Line 92 Selected Lines locations (Table 4 and Figure 8). Figure 8 showed that inbred line Assiut-1 gave the highest grain yield (8,356 kg/ha) averaged over environments and line Assiut-2 occupied the second place for grain yield (8250 kg/ha). ...

In wheat breeding, improved quality traits, including grain quality and dough rheological properties, have long been a critical goal. To understand the genetic basis of key quality traits of wheat, two single-locus and five multi-locus GWAS models were performed for six grain quality traits and three dough rheological properties based on 19, 254 SN...
To characterize FHB resistance, a set of 48 advanced inbred lines (AILs) along with two Egyptian cultivars (Sakha-93 and Giza-168) were evaluated for their resistance to the FHB during 2015/2016 and 2016/2017 under both greenhouse and field conditions. We identified some resistant AILs to the FHB including 37, 35, and 22 based on percentages of dis...
Here, we utilize the available next-generation sequencing (NGS) data to develop robust markers differentiating between salt-tolerant and sensitive wheat cultivars. First, we analyzed multi-transcriptomic datasets for salt-tolerant cultivars to identify the shared differentially expressed genes (DEGs). The identified shared DEGs (31 sDEGs) were extr...
The purpose of the study was to estimate the effect of sunflower and pea on the amount of productivity, protein and gluten percentage in grain. The objects of the study were 13 winter bread wheat varieties (Triticum aestivum L.) developed by the Agricultural Research Center “Donskoy”. The study was carried out in 2018-2020 on the fields of the depa...

... Together, they import more grain than all of South America (Stecker 2011). This is because most land in Egypt are deserts ( Khieralla et al. 2011).

... Newly reclaimed soils in these deserts suffer from various stresses such as drought, salinity, nutrient deficiency, etc. ( El-Fouly et al. 1984). On the other hand, population increase in Egypt is taking place at an alarming rate of 2.52-8%/annum ( Khieralla et al. 2011). This tremendous increase in population is one of the most serious challenges the country now faces. ...
The climate is changing all over the world, particularly in semi-arid and arid regions. This changing climate could strongly affect wheat production worldwide. As the world population continues to grow, and water resources for crop production decline and temperature increases, so the development of heat- and drought-tolerant cultivars is an issue of global concern. In this context, two cycles of selection were employed in the F2 generation of a cross between bread wheat (Triticum aestivum L.) ‘Long spike 58’ and ‘Giza-168’ to assess the impact of selection on grain yield in response to drought. Family selection and within-family selection were adopted in the second cycle of selection. The observed response to selection for grain yield was 64.66% in the F3 generation and 18.14 and 12.39% in the F4 generation for family and within-family selection, respectively. The mean grain yield of F3 selections exceeded that of two standard cultivars (‘Giza-168’ and ‘Sids 12’) by 19.67 and 16.48%, respectively, while the mean of F4 selections exceeded that of the two standard cultivars by 15.08 and 35.53%, respectively. Significant positive correlations were obtained for 1000-grain weight (32.34), number of kernels spike-1 (24.8) and spike length (12.55) in the F3 generation but not in the second cycle of selection. Generally, the observed responses to selection were greater than the predicted responses indicating the presence of dominant gene effects for the traits studied.

Random amplified polymorphic DNA (RAPD) primers associated with drought tolerance was used in this study to characterize drought tolerance in six wheat genotypes with developed marker assisted drought tolerance. Four of them were tolerant and two were drought sensitive genotypes. The results indicate that tolerant genotypes harbored seven positive RAPD markers, while sensitive genotypes had only one negative RAPD markers. In tolerant genotypes, seven positive PCR-RAPD markers with molecular sizes of 1050, 390, 200, 230, 850, 430 and 800 bp was exhibited by A-12, B-05, C-12, E-10 and B-02 primers. This study indicates that the seven positive markers can be used as indicators to discard drought tolerance in wheat marker-assisted breeding programmes.
