Abstrakt

The comparison of the population per se performance and the combining ability of 19 genetic resources and 5 adapted populations demonstrated that genetic resources might be integrated in hybrid rye breeding programmes without previous selection for yield. However, highly heritable traits like straw length and susceptibility to lodging should be improved before.
