What is it about?

The current study was carried out (a) to investigate the physiological responses of H. spontaneum genotypes to salinity stress, (b) to determine the adaptation strategies in the salinity‐tolerant genotypes of the wild barley under high salinity stress (300 mM NaCl for 4‐weeks).

Why is it important?

Hordeum spontaneum is the most closely related species to the cultivated barley (Hordeum vulgare) and provides the required source of genes for tolerance to abiotic and biotic stresses for improving the domesticated barley.

Perspectives

The wild barley accumulated much less Na in the leaf and root tissues in comparison with the cultivated ones. Therefore, the results showed that H. spontaneum is a kind of ion (Na) excluder species and that the six salinity‐tolerant genotypes are the superior salt excluders among the 47 wild barley genotypes. Given the homologous nature of the two subspecies, improvement of ion exclusion (Na) or K/Na selectivity using H. spontaneum germplasm is a more rigorous and practical approach than using other wild Hordeum species (i.e. halophyte H. marinum) for the introgression of salinity tolerance into the cultivated barley.
