Soil salinity has a considerable
negative effect on agriculture worldwide, including the GCC. Salinity has
already affected over 20% of the area of irrigated lands, and this is
increasing. Barley (Hordeum vulgare ssp.
vulgare) is the most salt-tolerant cereal crop and development of salinity-tolerant
barley lines will help to cope with this problem.
The project will study
agronomic and morphological characteristics of 1,847 barley lines under normal
and saline conditions. The barley lines will be compared in saline and
non-saline environments. In particular, the following will be done:a. Mapping salinity tolerance, as measured by yield under saline
b. Mapping traits that can only be measured in field conditions and
which are hypothesized to contribute to salinity tolerance in field conditionsc. Correlating salinity tolerance in the field with a range of traits
that are hypothesized to contribute to the maintenance of yield under saline
