Allelism of two genes for stem rust resistance in triticale

摘要

Inheritance studies involving Coorong and Satu triticales showed that each possessed a single dominant gene for resistance. The genes were allelic or closely linked. The relative frequencies ofSr27(Coorong gene) andSrSatuin a sequence of International Triticale Screening Nurseries were similar. However, a significant increase in the frequency of entries with SrSatuoccurred in the 17 International Triticale Screening Nursery (ITSN).
