“…It is a robust crop in the context of climate change. In Egypt, barley is grown in winter in both old and newly reclaimed lands that experience problems with soil fertility and salinity, and access to irrigation (El-Khalifa et al, 2022). Barley is also the most adapted field crop grown under drought and poor soil fertility in rainfed areas in Marsa Matrouh and the North Sinai.…”

“…Barley can be used as animal feed and for malting, but also has unique human health and nutritional benefits, including its high nutritional fibre content and beta-glucan content, which is assumed to reduce cholesterol levels (El-Khalifa et al, 2022) A functional barley seed delivery system is crucial to introduce and disseminate these varieties into the areas of their adaptation through a community-based seed production and distribution system involving farmers, research and extension services.…”

Egypt is the agribusiness powerhouse of the Middle East and North Africa (MENA-region), watered by the Nile, with age-old soils in the delta, desert oases and the Nile, and with farming experience capable of greening the desert with productive agriculture. It is not only the region's primary producer of many crops like potatoes and onions; with over a hundred million people it is the greatest consumer market and biggest labour reservoir. Egypt is a major producer and exporter of agricultural products such as especially citrus and potatoes, which support Egypt's food security and unlock opportunities for Egypt's local market and export.To the Netherlands, Masr (Egypt) is not a pure development partner country, like fragile states in the Sahel or the Horn of Africa. Rather it is a 'combi-country' where we work on an integrated cooperation, trade and investment agenda. With a focus on Climate and Water Smart Agriculture the NL-Masr Agri-food Network will work with Dutch, Egyptian and international partners on the basis of mutual interest mutual benefit to create innovative, inclusive and sustainable win-wins.While the Egyptian agriculture sector is mature, it is not yet future proof. It is facing challenges such as water scarcity, contamination of soils and water due to excessive chemical input use, and land fragmentation, in the face of climate change, disrupted global supply chains and population growth. This creates a pressure to go from agri-business as usual to more resilient farming and agri-business models, based on investing in the soil, investing in collaboration, and investing in local innovation.The seed sector is central to responding to these challenges, by providing improved varieties for climate resilience. This requires attention that traits beyond productivity, taste and esthetics should be taken along, but also tolerance and resistance to pests, diseases, heat and salinity. The Integrated Seed Sector Development approach, developed by applied researchers at WUR will be especially suited to these challenges. Pluriformity will support the diversity needed for a transition to a food system able to provide sufficient, healthy and sustainable diets for all. This will allow Egypt to develop its own specific public-private approach to provide access to the seeds that farmers need to serve people, planet and profit.

“…It’s not just used as food for people and animals anymore – it’s also important for making malt, beer, and biodiesel. In 2020/2021, production was 160.53 million tons, but it fell to 147.05 million tons in 2021/2022 [ 7 , 8 ]. However, the productivity of rainfed barley in Egypt is higher than the global average productivity [ 9 ].…”

As climate change increases abiotic stresses like drought and heat, evaluating barley performance under such conditions is critical for maintaining productivity. To assess how barley performs under normal conditions, drought, and heat stress, 29 different varieties were examined, considering agronomic, physiological, and disease-related characteristics. The research was conducted in five environments: two normal environments in 2020/2021 and 2021/2022, two drought stress environments in 2020/2021 and 2021/2022, and one heat stress environment in 2021/2022. The results demonstrated that genotype and environment significantly influenced all traits (p < 0.05), except canopy temperature, while genotype x environment interaction significantly influenced most traits, except total chlorophyll content and canopy temperature. Heat and drought stress environments often resulted in reduced performance for traits like plant height, spike length, grains per spike, and 100-grain weight compared to normal conditions. Based on individual traits, genotypes 07UT-44, 06WA-77, 08AB-09, and 07N6-57 exhibited the highest grain yield (4.1, 3.6, 3.6, and 3.6 t/ha, respectively). Also, these genotypes demonstrated enhanced stability in diverse drought and heat stress conditions, as assessed by the mean performance vs. stability index (Weighted Average of Absolute Scores, WAASB). The multi-trait stability index (MTSI) identified 07UT-44, 07UT-55, 07UT-71, and 08AB-09 as the most stable genotypes in terms of the performance of all traits. The imported lines demonstrated superior performance and stability, highlighting their potential as valuable genetic resources for developing climate-resilient barley.

“…Breeding is crucial for creating toolkits of salt-tolerant crop genotypes and for implementing growth, physiological, and yield features in the field [ 33 ]. According to El-Khalifa et al [ 34 ], barley is an essential crop in Egypt and takes up 76.9% of freshly reclaimed land. Also, Mohamed et al [ 14 ] reported that, barley productivity in Egypt reached 108,000 tons in 2019 and is predicted to continue rising.…”

The aim of this study was to evaluate the impact of salt stress on morphological, yield, biochemical, and molecular attributes of different barley genotypes. Ten genotypes were cultivated at Fayoum Research Station, El-Fayoum Governorate, Egypt, during two seasons (2020–2021 and 2021–2022), and they were exposed to two different salt concentrations (tap water as a control and 8000 ppm). The results showed that genotypes and salt stress had a significant impact on all morphological and physiological parameters. The morphological parameters (plant height) and yield attributes (spike length, number of grains per spike, and grain yield per plant) of all barley genotypes were significantly decreased under salt stress as compared to control plants. Under salt stress, the total soluble sugars, proline, total phenol, total flavonoid, ascorbic acid, malondialdehyde, hydrogen peroxide, and sodium contents of the shoots of all barley genotypes significantly increased while the potassium content decreased. L1, which is considered a sensitive genotype was more affected by salinity stress than the tolerance genotypes L4, L6, L9, and Giza 138. SDS-PAGE of seed proteins demonstrated high levels of genetic variety with a polymorphism rate of 42.11%. All genotypes evaluated revealed significant variations in the seed protein biochemical markers, with new protein bands appearing and other protein bands disappearing in the protein patterns of genotypes cultivated under various conditions. Two molecular marker techniques (SCoT and ISSR primers) were used in this study. Ten Start Codon Targeted (SCoT) primers exhibited a total of 94 fragments with sizes ranging from 1800 base pairs to 100 base pairs; 29 of them were monomorphic, and 65 bands, with a polymorphism of 62.18%, were polymorphic. These bands contained 21 unique bands (9 positive specific markers and 12 negative specific markers). A total of 54 amplified bands with molecular sizes ranging from 2200 to 200 bp were produced using seven Inter Simple Sequence Repeat (ISSR) primers; 31 of them were monomorphic bands and 23 polymorphic bands had a 40.9% polymorphism. The techniques identified molecular genetic markers associated with salt tolerance in barley crop and successfully marked each genotype with distinct bands. The ten genotypes were sorted into two main groups by the unweighted pair group method of arithmetic averages (UPGMA) cluster analysis based on molecular markers and data at a genetic similarity coefficient level of 0.71.
