Global climate change is accelerating the process of soil salinization. Salinity restricts wheat
production worldwide, including in Egypt. Thus, it is recommended to screen for salt-tolerant
genotypes according to salinity tolerance related traits. The present study aimed to evaluate the
salinity tolerance among 159 spring bread wheat elite genotypes and to compare them with the 16
Egyptian checks. Thus, the genotypes were evaluated under saline conditions in El-Arish, Egypt
(EC 10 Ds/m). The field experiment was laid out in an alpha lattice design. Data for the thousandgrain
weight, highest plant survival rate, plant height, number of seeds/spike, number of
spikes/plant and seeds/spike, spike length and spike weight were collected in the field. Interestingly,
the elite wheat genotypes 30351 and 30383 were observed to have maximum values for the
thousand-grain weight in comparison with the other wheat genotypes under study. The results of
this study suggest that the Egyptian varieties, sids1, sids12, sids13 and Gemmiza12, had maximum values for seeds/spike, spike length and spike weight, respectively. Thus, it is recommended to cross
these superior genotypes with the elite genotypes to improve their performance in the seeds/spike,
spike length and spike weight.
