Abstract EN
This study examined seven barley genotypes in two evaluation experiments; the 1st under normal condition at Sakha
station while the 2nd under salt stress at the El-Hosinia station, during two growing seasons (2016/2017 and 2017/2018)
and made Laboratory experiment at Seed Technology Research Unit in Mansura, Dakahalia Governorate, Field Corps
Research Institute, Agricultural Research Center, Egypt.
During 2017 season to study the efficacy of barley seed with
characters under different salinity levels(0, 10, 12, 14 and 16 dSm-1) using Rashid salt.
The randomized complete block
design with 3 replications was used for each experiment.
Nine traits were recorded, days to heading, days to maturity,
plant height (cm), spike length(cm), No.
of spikes m-2, No.
of grains spike-1, straw yield (t.
ha-1), grain yield (t.
ha-1) and
harvest index (HI).
Other five traits were recorded in Laboratory experiment; shoot length, root length, seedling dry
weight (g), K+ content and N+ a content.
Besides, eight stress tolerance indices were evaluated (TOL, MP, STI, GMP, Yr,
DSI, YSI, YI).
The combined analysis of variance for years, locations, genotypes, and interaction was significant and
highly significant for all studied traits; Results revealed that Line 4, Line 2 and line1 gave the highest values under two
conditions in both seasons for grain yield (t.
ha-1).
For indices of salinity tolerance, the Productivity MP Values obtained
by Line4; Line2; Giza123 and Line1.
Moreover, these four tolerant genotypes recorded high values for GMP, STI, YSI,
and YI.
Significant differences were observed between salinity levels, whereas level (10dSm-1) was lowest harmful in
connection.
Compared with other Salinity levels.
On the other hand, the highest harmful of parameters was obtained by
Salinity level(16 dSm-1).
