Brief description

Three triticale lines, Sir&you, M2A-Beagle and OK 77842, have been reported to possess resistance to bacterial leaf streak caused by Xanthomonas campestris pv. translucens (Xct). The three resistant lines were crossed to susceptible lines and crossed with each other. F2, BCt-Fi, BCz-Ft plants were inoculated with a mixture of two Xct strains. The segregation data indicate the presence of a single dominant gene in each of the three resistant lines to bacterial leaf streak. These three genes are either the same or closely linked herein designated as Xct 1 (Johnson et al., 1987).
