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). ---- ===== References ===== Adhikari TB, Gurung S, Hansen JM, Jackson EW, Bonman JM (2012).
