Abstract

In the current study, 248 two-rowed and another 253 six-rowed spring barley (Hordeum vulgare L.) breeding lines from several US barley breeding programs were evaluated in multiple locations in Egypt to select for potentially adapted lines. The introduced plant materials were planted in two locations during three growing seasons (2015, 2016, and 2017). The focus of the first growing season was to increase available seeds and collect preliminary observations. During the second and third growing seasons, the advanced plant materials and local check cultivars were planted in an incomplete block design in two replicates within three locations. Grain yield, leaf rust, number of days to flowering, and plant height were measured. Based on grain yield production, the top 94 lines from the two-rowed and 100 from the six-rowed barley lines were selected and advanced for further evaluation in 2017. The introduced materials contained several lines that consistently outperformed the check cultivars. Therefore, these lines could be used as parents to improve barley production and enhance genetic diversity or be directly released as cultivars after appropriate testing in Egypt.

Funding Information:
This work was partially funded by the Science and Technology Development Fund (STDF), Egypt, Grant no. 14935, and the wheat breeding program in the University of Nebraska-Lincoln. Without the barley germplasm that was collected by the Triticeae Coordinated Agricultural Project (TCAP), the reported research would not be possible. Thus, we sincerely appreciate all the great work of the TCAP team. Moreover, most of the work reported in this manuscript was conducted in the wheat breeding laboratory, Damanhour University, Egypt. For that, we thank the wheat breeding team for all their help and technical support we received. We thank both Mr. Hafiz Mazeek and Mr. Talaat Salah, Damanhour University, Egypt, for their effort during this experiment. We would also like to show our gratitude to graduate and undergraduate students who helped us during the summer fieldwork.
