Summary

Thirty lines from a cross between VPM/ Moisson 421 and Selection 101 were used in the study to determine whether strawbreaker foot rot resistance derived from Aegilops ventricosa was associated with an allele for endopeptidase. The progeny examined for foot rot lesions represented F2 derived F5 lines and enzyme assays were done on F6 seedlings. The results indicate that the wheat and ‘VPM/Moisson 421’ endopeptidase alleles are distinctly different. The endopeptidase allele frequencies of 30 lines were compared with strawbreaker foot rot resistance as measured by the lesion severity index. The results demonstrate a close association between the gene for strawbreaker foot rot resistance and the endopeptidase allele derived from Ae. ventricosa.
