Abstract
An attempt to introduce genes for sprouting resistance from the resistant inbred line Ot1-3 to Polish rye cultivars was performed. In the course of study, five BC2 crossess between cvs. Dańkowskie Złote, Wibro, Warko, Amilo, Danko and the inbred line were developed. Their F1–F6 generations were selected for sprouting resistance and high yielding traits. Majority of thus selected strains proved to inherit unsatisfactory features from the line Ot1-3, which determined their low breeding value. Sprouting resistant and well yielding strains were developed only from the cross with cv. Wibro as maternal parent. Strain A100 shows high falling number — similar to that of sprouting resistant cv. Amilo and the strain A94 exhibits the highest level of sprouting resistance among studied materials.
