Phenotypic and Physiological Evaluation of Two and Six Rows Barley under Different Environmental Conditions

Abstract

In recent years, barley has attracted more interest as a food and feed source because of its high soluble dietary fiber and β-glucan content compared with other small grains. Twenty-five barley genotypes (20 imported genotypes and five check cultivars) were grown in three environments for two successive seasons: 2015/2016 and 2016/2017. The first environment was in El-Nubaria, Alexandria, Egypt during 2015/2016, while the second and third environments were in El-Bostan, Elbhera, Egypt during 2015/2016 and 2016/2017. The experiments were conducted in a randomized complete block design with the three replicates. The primary objectives of the current study were to evaluate the performance of 20 imported barley genotypes under several environmental conditions. The imported materials were superior to the local commercial cultivars for several traits, including grain yield. Therefore, the superior genotypes will be further evaluated and used in barley breeding programs. Our future work will focus on creating several crosses among the selected superior genotypes to improve yield and other important traits, while applying marker-assisted selection.

Nebraska winter wheat unexpected flowering in Egypt: New improvement opportunities

“…yellow) rust (YR, caused by Puccinia striiformis Westendorp f. sp. tritici) was conducted by visual scoring as a percentage of leaf area infected for each wheat plot under the open field condition as have been previously reported by Naser et al (2018) and Elbasyoni (2018). GY was determined by harvesting the four rows of each plot and expressed as ton ha −1 .…”

Reverse introduction of two‐ and six‐rowed barley lines from the United States into Egypt

“…In addition, barley is globally considered as a crop for marginal lands, where the production conditions are less suitable for other cereal crops such as wheat (Triticum aestivum L.) (Lalani, Al-Eter, Kassam, Bapoo, & Kassam, 2018). Growing barley in marginal lands or under low-input conditions might explain yield reduction in regions such as Egypt, in which barley grain production was decreased from 3.03 t ha −1 during the 2001-2002 growing season to 1.54 t ha −1 during 2014-2015 growing season (Naser, Badran, Abouzied, Ali, & Elbasyoni, 2018).…”

“…The line details and other important information (i.e., seed sources, selection history, head type, and pedigrees) can be found on the T3/barley website (https://triticeaetoolbox.org/barley/) and in Supplemental Table S1. In addition to the imported lines, four six-rowed cultivars (Giza123, Giza132, Giza134, and Giza136) and one two-rowed cultivar (Giza127) were obtained from the ARC and used as local check cultivars (pedigree and other information about the check cultivars can be found in Naser et al, 2018).…”

“…The significant phenotypic variation observed among the introduced lines could be attributed to the differences in their origin and genetic makeup, whereas the difference in the genotype response pattern across locations might be due to the difference in the agroecological conditions among the three locations (Elnubaria, Elbostan, and Elkhazan) (Naser et al, 2018). It was surprising that some of the introduced lines outperformed the local check cultivars with regard to GY, given that the check cultivars are among the recommended and widely grown barley cultivars in Egypt and in the testing locations.…”

Evaluation of Different Barley Genotypes for their Phenological Traits, Yield and Yield Attributes in the Western Mid-Hill of Nepal

“…Barleys are used for making sattu and khole in high hills and in mountainous regions (Paudel, 2016). The presence of high dietary fiber and β-glucan in barley makes it a better choice over other cereals (Naser et al, 2018). Barley has prospects for diverse end uses.…”
