Abstract
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 was 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 revealed 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.
