Abstract

Field experiments were conducted under rainfed conditions during 2014–15 and 2015–16 growing seasons at two locations [Maru Research Station (Maru) and Jordan University of Science and Technology Research Station (JUST)] in northern Jordan to evaluate four barley (Hordeum vulgare L.) cultivars (Rum, ACSAD 176, Athroh and Mutah) for their stability, yield and yield components characters under both drought prone environment and intermediate drought prone environments. Our results indicated that barley plants (Hordeum vulgare L.) at the semi-arid location at Maru had higher biological and grain yield than those grown at the arid location at JUST. Grain yield during the second growing season was lower than the first growing season. Regarding barley yield, our data indicated that in both growing seasons barley cultivars did not vary significantly in their productivities (grain yield and biological yield). To evaluate the phenotypic stability and adaptability of the tested cultivars, the GGE biplot methods were performed. Generally, this work showed that there is a specific adaptation to the testing environment.
