Summary

The impact of seed source (conventional or organic farming) is one important question for the variety trials under the conditions of organic farming. Hence, field trials were
conducted at two sites in Bavaria in two years (2013-2014). Certified organic seed from a Bavarian propagation were compared to conventional seed, offered by breeders for national variety trials. One until two varieties were examined for winter rye and for winter triticale in each year. Organic seed often showed higher crude protein content, conventional seed had mainly higher thousand seed weight and often superior germination power.
The grain yield was mostly higher for conventionally produced seeds than for organic seed at one site, whereas seed source showed no differences with one exception at
the other site. A high positive correlation was determined for yield and above all germination power for rye. But all in all, data basis is too low for general conclusion.
Future research should focus on more varieties and different soil and climate condition. Seed should be difference concerning cultivation only in the last year in future investigation.
