SOIL salinity is the major global limitation to wheat production. Thus, eight Egyptian
bread wheat cultivars were evaluated under normal and saline soil conditions
during two consecutive seasons 2020/2021 and 2021/2022 at the experimental farm of
Sakha Agricultural Research Station, Kafr Elsheikh, Egypt, eight wheat cultivars were
arranged at Latin square design. The objective was to evaluate eight Egyptian wheat
cultivars under the effects of salinity stress on yield and its components characteristics.
The studied traits were days to heading, days to maturity, grain filling period, grain
filling rate, plant height, biological yield, harvest index and grain yield and its
components. The behavior of tested wheat cultivars were different under normal and
saline condition due to the effect of soil salinity and the tolerance of the tested wheat
cultivars. The studied traits were varied significantly in their values for most traits
in the two seasons. All mean values of the studied traits decreased under the saline
conditions. Generally, at normal soil the genotypic main effect plus genotype by traits
analysis revealed that the best genotypes in studied traits was Giza 171 followed by
Sids 14 and Shandweel 1, and the lowest genotypes for all studied traits was Sids 12
under saline soil conditions, the best genotypes in most traits were Giza 171, Sids 14,
Gemmieza 12 then Misr 1 and Sids 12 was the lowest genotypes for all studied traits.
The current investigation revealed that the bread wheat cultivars Giza171 was the best
tested cultivar for all traits under normal soil and soil salinity condition. The wheat
cultivar Giza 171 can be recommended to be cultivated in salinity effected soil and
north delta.
