Résumé
A new line of barley achieves good crop yields even under poor environmental conditions. It has been bred by crossing a common variety of barley with various types of wild barley. The researchers then planted the new lines of barley in five very different locations around the world, observed the growth of the plants and analyzed their genetic make-up.

For the study, the research team crossed a typical barley variety with 25 types of wild barley. This resulted in 48 genetically different plant lines, which the research team planted at five very different locations around the world : Dundee (UK), Halle (Germany), Al Karak (Jordan), Dubai (United Arab Emirates) and Adelaide (Australia). Each of these places has its own environmental conditions : Australia and Dubai suffer from very salty, dry soils, Al Karak and Dubai from heat and drought. In Germany and UK, fields always receive additional nitrogen fertilizer in order to increase crop yields. During the cultivation period, the scientists observed the growth of the plants under environmental stress and compared the results to native varieties from a control group. "We then selected plants from our cultivation that grew particularly well on site and examined their genetic material more closely," continues Pillen. The researchers wanted to draw conclusions about the
