As part of the study, scientists evaluated a diversity panel of 377 two-row spring barley genotypes during the vegetative (in controlled-environment conditions) and reproductive (in field conditions) stages using an "interaction model" which considered the interaction between treatment (control and salinity) and genetic markers.

In controlled-environment conditions, scientists used a high-throughput phenotyping platform to assess growth-related traits under control and saline conditions, whereas in field conditions, agronomic traits were measured on plots irrigated with either fresh or saline water (15 deciSiemens per meter).
Study discovers new salt tolerance traits in two-row spring barley
10 October 2020
Soil and water salinity is a major constraint on agriculture, particularly in arid and semi-arid regions. Caused by a range of man-made and natural factors, including poor irrigation practices and seawater intrusion, it is exacerbated by climate change.
