Evaluating salinity tolerance in progeny of domestic and wild barley crosses at germination stage

Abstract Salinity is one of the most important challenges facing future global barley (Hordeum vulgare L.) productivity, as it causes major reduction in germination, growth, grain yield, and quality. Screening germplasm for salinity tolerance at germination is vital to breeding programs because germ...
