Summary translation

Yield stability is from particular importance in organic farming due to high impact of environmental conditions. Two hybrids and three population of winter rye were compared at two or three experimental sites in 2014 until 2017 in Bavaria. Both hybrids showed higher grain yields, but lower yield stability (higher coefficient of variances). The slopes for the hybrids in the regression analyses were higher. The yield difference between hybrids and population were twice as big in environments with high yield potential as in environments with inferior conditions.
