Genetic studies of salinity tolerance in barley in field conditions

Thematic Areas: 
Crop productivity and diversification
Problem Overview: 
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.

Purpose: 
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 conditions:
b. Mapping traits that can only be measured in field conditions and which are hypothesized to contribute to salinity tolerance in field conditions
c. Correlating salinity tolerance in the field with a range of traits that are hypothesized to contribute to the maintenance of yield under saline conditions
