Abstract
An F1 monosomic analysis was carried out on the A and B genome monosomics of Chinese Spring crossed with Triticum timopheevi, (Manitoba accession number 4B289) and T. durum desf. cv. Carleton, in an attempt to study the inheritance of the resistance of these two wheats to ergot, Claviceps purpurea. Chromosomes 1B and 3B of Carleton were found to condition resistance to ergot. A small part of the resistance of T. timopheevi was found to be conditioned by chromosome 3B. A major part of the T. timopheevi resistance was expressed in crosses with other tetraploids. It was thought that the suppression of the R. timopheevi resistance may be conditioned by the D genome of Chinese Spring.
