Evaluation of some Barley Genotypes under Saline Soil Conditions

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.

Yield Stability Analysis of Some Promising Barley Genotypes under Different Environmental Conditions

“…Heat stress before flowering can result in sterility and reduced output. The results are supported by those obtained by Hall [15], Cattivelli et al [14], El-Shawy et al [25], Agwa et al, [20], Mansour and Aboulila [30] and El-Mantawy et al [31]. The range of regression coefficients obtained, from 0.86 to 1.17, suggests that different genotypes respond differently to different environments.…”

“…The range of regression coefficients obtained, from 0.86 to 1.17, suggests that different genotypes respond differently to different environments. Overall, genotypes with high mean yield and regression coefficients (bi) close to 1.0 are generally considered adaptable and stable, similar to the findings of Gebremedhin [32], Elakhdar et al [33], Mansour et al [34] and El-Shawy et al [25], Mansour and Aboulila [30] and El-Mantawy et al [31].…”
