“…A major priority of plant pathology and plant breeding is to release high-yielding disease resistant wheat cultivar to specific abiotic and biotic stresses (Zhao et al, 2020;Zhao et al, 2021). FCR is a major biotic factor reducing the yield of wheat especially in drought persistent locations of the world.…”

Wheat (Triticum aestivum L) is the most important cereal crop worldwide. It is responsible for providing more than 40% of humans with their nutritional requirements from carbohydrates and other essential nutrients. Unfortunately, its attacked by different various air and soil borne pathogens which resulted in massive losses in both yield quantity and quality. In Egypt, wheat is not only just a nutritional cereal crop, but it is considered the food security key. There is a huge gap between the wheat grain production and national consumption levels. Therefore, saving each grain from wheat production deemed urgent need. Using resistant cultivars against important invaded pathogens is considering one of the most effective and relevant techniques that can be used in the battle between plant pathologists and hazardous pathogen i.e. Puccinia triticina and Fusarium pseudograminiarum. In the current study, the resistance potential of 29 different Egyptian wheat cultivars was assessed against 3 leaf rust races and crown rot disease individually. The results showed that the tolerance potential of the tested cultivars toward either P. triticina or F. pseudograminiarum was varied significantly. Also, the relation between the incidences of the two diseases was estimated. Results indicating that there are a positive correlation between incidence of leaf rust and incidence of crown rot diseases. These findings could lead to designing special models which can be used in the prediction of the incidence by one of the two pathogens when the other attacks the wheat plants.

“…Leaf tissues were ground by shaking the plates at 30 cycles per second for 3 min in a Mixer Mill (Retsch GmbH, Haan, Germany). Genomic DNA was isolated using the standard cetyltrimethylammonium bromide (CTAB) method with a slight modification ( Zhao et al, 2020 ). DNA quality was checked with 1% agarose gel and quantified in a FLUOstar Omega microplate reader (BMG LABTECH, Germany) using Quant-iT™ PicoGreen dsDNA assay kits (Thermo Fisher Scientific, Waltham, MA, United States).…”

Spring wheat (Triticum aestivum L.) is one of the most imperative staple food crops, with an annual production of 765 million tons globally to feed ∼40% world population. Genetic diversity in available germplasm is crucial for sustainable wheat improvement to ensure global food security. A diversity panel of 184 Pakistani wheat accessions was genotyped using 123,596 high-quality single nucleotide polymorphism (SNP) markers generated by genotyping-by-sequencing with 42% of the SNPs mapped on B, 36% on A, and 22% on D sub-genomes of wheat. Chromosome 2B contains the most SNPs (9,126), whereas 4D has the least (2,660) markers. The mean polymorphic information content, genetic diversity, and major allele frequency of the population were 0.157, 0.1844, and 0.87, respectively. Analysis of molecular variance revealed a higher genetic diversity (80%) within the sub-population than among the sub-populations (20%). The genome-wide linkage disequilibrium was 0.34 Mbp for the whole wheat genome. Among the three subgenomes, A has the highest LD decay value (0.29 Mbp), followed by B (0.2 Mbp) and D (0.07 Mbp) genomes, respectively. The results of population structure, principal coordinate analysis, phylogenetic tree, and kinship analysis also divided the whole population into three clusters comprising 31, 33, and 120 accessions in group 1, group 2, and group 3, respectively. All groups were dominated by the local wheat accessions. Estimation of genetic diversity will be a baseline for the selection of breeding parents for mutations and the genome-wide association and marker-assisted selection studies.

“…Deploying resistant wheat cultivars harboring H genes is the most effective and economical way to manage this insect pest (Berzonsky et al 2002;Schmid et al 2018). To date, 37 genes (H1-H36 plus Hdic) have been identified (Liu et al 2005;Sardesai et al 2005;Subramanyam et al 2016;Zhao et al 2020). However, extensive deployment of resistant wheat lines exerts strong selection pressure on Hessian fly populations resulting in the development of virulent biotypes (Johnson et al 2017) posing a severe threat to wheat production, thereby necessitating the need to identify and employ alternate strategies that can enhance and complement native or introgressed H gene resistance.…”
