| Abstract: | Genetic control of leaf rust resistance is studied by the hybridological analysis method in hexaploid triticale cultivars Matyrskoe, PRAG 140/1, BG 13, Tal’va 100, Kartli 6, Kolor, AD-52, PRAG 72, and PCHL Tel 216. Mono-or digenic inheritance of resistance is shown as a result of crossing with susceptible cultivars Viktor and Slavyanin. Susceptible plants are found in all F2 hybrid populations obtained from crossing resistant cultivars, which indicates nonidentity of resistance genes and their high diversity. |
