The aim of the present work was to evaluate performance 20 barley genotypes and find out genetic diversity these for salt tolerance using simple sequence repeats during two consecutive seasons; 2009/2010 2010/2011. Twenty differed in their potentiality against salinity were planted screening field experiments at locations; Sakha, North Egypt (as a control) El-Serw saline site) detect stress. They randomized complete block design with three replicates. Results revealed that Egyptian cultivars...

<b>Background and Objective:</b> Barley is considering one of the most important cereal crops at local global levels. It ranked second in terms nutritional importance after wheat its flour contributes significantly to bridging large gap production Egyptian bread. The aim this study concentrated on knowing testing genetic behaviour responsible for salinity stress tolerance barley as trying improve crop increase ability abiotic resistance under conditions. <b>Materials...

The most serious damage caused by saline stress on plant growth is the severe effect and in metabolism processes resulting from decreasing water level needed to wash salts direct toxicity, anti-ions, nutrient disruption (Neumann, 1977).Also, it largely causes physiological dehydration (Munns, 2002).Among greatest damages

Abiotic stresses in particular water stress which was considered important that affecting all crops the world and Egypt.The aim of present work to evaluate performance 15 Egyptian barley cultivars find out genetic diversity these for tolerance using simple sequence repeats (SSR) during two consecutive seasons detect their stress.Results revealed Giza 126, 131 2000 were as tolerant cultivars, they exhibited highest mean values studied morphological physiological traits.Twenty alleles produced...

Assessment of phenotypic and genotypic diversity is one the principal important steps in plant breeding programs.In this study, field screening analysis was carried out Sakha Agricultural research station during two growing seasons 2018/ 2019 2019/ 2020 to investigate among 15 Egyptian barley cultivars using physiological, grain quality, yield yieldassociated traits assess genetic by Sequence-Related Amplified Polymorphism (SRAP) marker analysis.Analysis variance showed high variability all...

Barley is an important food crop particularly for animal feeding and human over the word, which infested by Rhyzopertha dominica (F.) insects at stored grain stage. Using modern methods of protection grains from insect pests within integrated management (IPM) programs approach. Ten hulled Egyptian barley cultivars were grown Sakha Agricultural research station farm during two growing seasons 2020/ 2021 2021/ 2022 to evaluated their susceptible R. after 180 days seeds storage. The influence...

Barley (Hordeum vulgare L.) is one of the most important food and feed crops in world, which infested with several insect pests, main economic pest aphid causes direct damage indirect barley production. The integrated management (IPM) programs are requirement to reduce aphids’ damages, by using chemical substances extracts obtained from plants as an alternative synthetic control for its satisfactory effectiveness control. insecticidal effect aqueous extract hot pepper quinoa’s saponin on...
