“…Column dendrograms show the 16 phenotypic traits and the 15 SSR primers. Khatab et al 2021;Mehta et al 2021;Mariey et al 2022a). They used SSR markers to investigate genetic diversity and genetic relationships among Barley genotypes for salt stress conditions, and they reported that the SSRs technique could consider a powerful tool for genetic studies in barley breeding for salinity stress Figure 7.…”

“…Those markers provide important information about a species, as they have a high polymorphism rate, co-dominant inheritance, high reproducibility, locus specificity, and random distribution on the genome (Brbaklic et al 2021). Moreover, SSRs are powerful markers that are excellent for assessing genetic diversity and crop improvement for salinity stress tolerance (Mariey et al 2016;Khatab et al 2021;Mehta et al 2021;Mariey et al 2022a).…”

“…Hence, successful salinity tolerance breeding programs must adopt a strategy to identify salt-tolerant genotypes by identifying comprehensive donating characteristics such as physiological, morphological, and biochemical traits. Therefore, metabolic pathways with molecular markers recognize their contribution to salt tolerance to improve and increase crop yields in saline areas to produce enough food for the increasing global population (Mwando et al 2020;Khatab et al 2021). So, the association of molecular markers with phenotypic evaluation is an important factor in investigating tolerance's genetic role by predicting the genomic regions that affect plant response.…”

Abstract. Mariey SA, El-Bialy MA, Khedr RA, Mohamed EN, Meleha AMI, Khatab IA. 2023. Comprehensive evaluation and economic analysis in some barley genotypes under soil salinity. Asian J Agric 7: 20-33. Soil salinity is one of the abiotic stresses that cause a significant reduction in barley production. Understanding the phenotypic and genetic diversity among Barley genotypes is necessary to improve barley salt tolerance. Herne comprehensive sets of morph-physiological, grain quality traits and Simple Sequence Repeat (SSR) markers combined with economic analysis were done to determine the phenotypic and genetic variation of eight barley genotypes under salinity stress during seasons 2019/2020 and 2020/2021. High genetic variation was observed among studied genotypes for all measured traits. Salinization caused a significant increase in (Sodium content, soluble carbohydrate content, and crude protein content %) in sensitive genotypes (Giza 132 and line 1). SSRs markers generated clear patterns with high polymorphism with 31 alleles by an average of 2.07 alleles per locus. Out of 15 SSR markers, nine (Bmac 0209, Bmag 0011, Bmag 125, Bmac 0871, Bmag 770, Bmac 701, Bmag 0387, Bmac316, and Bmag 0009) were highly useful in distinguishing tolerant and sensitive Barley genotypes. Soil salinity decreased the benefit-cost ratio for Giza 123,136 and 137, which appear beneficial as salt-tolerant cultivars. Those cultivars had low reductions for almost studied traits and had the highest grain yield production due to increasing the farmer's income under salt affect area.

“…Molecular plant breeding is an interdisciplinary science revolutionizing crop improvement in the twentyfirst century (Lörz & Wenzel, 2005;Varshney et al, 2006;Eathington et al, 2007;Mumm, 2007;Adeyemo et al, 2020;El-Badan et al, 2021). As a result, the most crucial aspects of molecular breeding are the detection and characterization of genetic markers (Stephen & Mumm, 2008;Voosen, 2009;Khatab et al, 2021). Molecular genetics frequently apply an "investigative technique" to detect the structure and function of a gene in a plant's genome using genetic screens by one and multi-molecular markers (Waters, 2013;Alberts, 2014).…”

Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ 26 T HE GENETIC diversity of some Egyptian barley cultivars was assessed using twelve primers from the inter-retrotransposons amplified polymorphism (IRAP) marker system. In addition, moisture content, crude, lipids, ash, and crude fiber contents were measured in the studied cultivars. The obtained results showed that the average protein content was 11.19%, and the highest one was recorded for Giza135 cultivar with an average value of 12.3% to a lesser extent in Giza 129 (8.7%). Sixty-three IRAP bands, scores of 33.3% and 66.7% of monomorphic and polymorphic bands were recorded, respectively. The polymorphism heterozygosity index values IRAP marker traits were ranged as H (0.04--0.47), PIC (0.04-0.36), E (7.50-11.75) HAV (0.00-0.01), MI (0.04-0.07), D (0.04-0.61), and R (0.5.-6.86). The proportion of appearing polymorphism was 63%. This multiplicity was used to measure the difference between the studied cultivars; however, there were no unique bands in all cultivars for each IRAP primer. There was a similarity between the PCA, heat map, and dendrogram distributions of Giza123, Giza124, Giza125, and Giza126. The Bioplot analysis divided the cultivars into four groups. The data revealed a significant difference, among the surveyed varieties of barley cultivars in Egypt, at the molecular level.

Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ 50 T HIS STUDY deals with the effects of tri-factorial interaction on some traits (elongation; weight and biomass accumulation efficiency of roots) and anatomical features of seedling Simmondsia chinensis roots. The obtained data indicated that, the moderate sodicity affected the root length which was enhanced by the sub optimal and optimal temperatures with low salinity stress. The decreased root elongation was inhibited under supra optimal temperature with decreased Ψ s . Statistically, the Ψ s had a dominant role while temperature effect was secondary on the root length and weight. It was found that, the temperature ranges from 20 to 28 was favorable for well development of the root anatomical structures and the root hairs formation, particular at low osmotic stress and moderate sodicity. Adversely, the elevated temperature had a deleterious effect on the root circulation which caused a wider vascular cylinder with narrower root cortex, as well as a distortion {lysis} of parenchymatous cells. The effect of the investigated factors and their combinations on the efficiency of cortical layer and xylem vessels was discussed.
