High Buffering Potential of Winter Wheat Composite Cross Populations to Rapidly Changing Environmental Conditions

A winter wheat composite cross population (CCP), created in the UK 2001, has been grown Germany, Hungary, and since 2005 (F5 generation). In 2008/09 (F8), a cycling pattern for populations was developed between partners to test effects of rapidly changing environments on agronomic performance morphological characteristics. One CCP by eight one year subsequently sent next partner, creating “cycling CCPs” with different histories. 2013, all CCPs three non-cycling (from UK) were included two-year experiment Germany line varieties as references. Differing seed weights F13 at sowing affected some parameters under drought conditions 2014/15 but not less stressful 2013/14. both experimental years, comparable terms performance, yielding more than 2015. The results highlight potential compete varieties, while overall similarity based their origin history traits indicates high buffering highly variable environmental conditions.
