“…Therefore, selection genotypes based on increased or stable chlorophyll content can prevent yield losses under salt ~ 128 ~ stress conditions. Also, salinity stress significantly decreased germination percentage, root and shoot length and fresh weight as well as chlorophyll and proline content [39,40,41] . The quantitative salinity tolerance indices Yield stress (YS), yield potential (YP), tolerance index (TOL), mean Productivity (MP), yield reduction ratio (YR), stress tolerance index (STI), yield stability index (YSI) and yield index (YI) were calculated for the evaluated genotypes (Table 12).…”

This study examined ten barley genotypes under both normal and saline soil environments at Sakha Agricultural Research Station, during two growing seasons 2019/2020 and 2020/2021. A randomized complete block design with four replications were used for each experiment. Some traits were recorded i.e. days to maturity, plant height (cm), spike length (cm), number of spikes m -2 , number of grains spike -1 , grain yield (t ha -1 ), biological yield (t ha -1 ), chlorophyll, K, Na content and K/ Na ratio. Analysis of variance for years, locations, genotypes and interaction were significant and highly significant for all studied traits. Results revealed that, the evaluated genotypes reveled a wide variation in salinity sensitivity. Line-1 and Line-6 gave the most desirable values of yield and related traits as well as physiological parameters under studied environments in both seasons, so we can recommend those genotypes under salinity conditions.

Drought and salinity are among the most important abiotic stress factors that limit the productivity in economically important plants. Although genes from wild relatives or unadapted germplasm have often been used for stress tolerance breeding, only few studies have examined wild relatives to understand the genetic and molecular basis of stress tolerance. In this study, we monitored the changes in gene expression profiles of leaf and root tissues of two wild barleys (Hordeum spontaneum L.) accessions from Israel after treatment with salt (NaCl) and drought (PEG) stress. We identified a total of 641 differentially expressed genes across 24 conditions (2 accessions, 2 stress conditions, 2 tissues and 3 time points). Our gene expression analyses revealed large numbers of differentially expressed genes in different accessions by different stress treatments. In addition, the number of genes altered in the leaves of stress-exposed plants of both genotypes was higher than those altered in the roots. Interestingly, there was a relatively little overlap between the leaf and the root stress-responsive gene expression patterns, suggesting that different stress-associated processes might be operating in these tissues during stress adaptation. Overall, our results revealed a number of candidate genes and plant processes associated with stress tolerance in wild barley. Wild barley would be a useful source of new genetic variation for drought and salt stress tolerance. Our results could provide new insights into the mechanisms of drought and salt stress tolerance in wild barley and should be useful for genetic improvement of salt-drought tolerance in cultivated barley.
