Summary. At the first stage of long-term studies to assess the initial stock for spring wheat breeding process on resistance to leaf rust in Krasnoyarsk Research Institute on Agriculture 476 samples have been studied. The initial stock was presented by immunological collection of Dr. Nielsen’s (Canada), a collection of sources of resistance to rust obtained from Research Institute of Agriculture (Jambul), material of Krasnoyarsk testing station by All-Russian Institute of Plant Production (VIR). Depending on genotype 42 samples displayed 42 immune stability immune and 49 – highly resistant reaction (reaction type I). The best of them by productivity were Erythrospermum 17430 ( Russia), Era/ Pembina, BW- 90 (Canada ), K- 46391, K- 46493, K- 46494, K- 46394 (Chile), Era, Grim (USA), Ures, K-48031 (Mexico). By 2005, nearly from 2 000 samples of wheat collection 151 sources of resistance to P. triticina were isolated. The most promising of them were Tuleevskaya, Sonata, Isheevskaya, Sp-5679, Obskaya 14, Izumrudnaya, Cutless, Saratovskaya 52, K-46394, Kharkovskaya 22, K-46494, Dong Nong, K-46493, Cris varieties. While implementing the program on creation of own sources of resistance to leaf rust the hybridization of 235 combinations was held and 41 000 samples were studied on disease resistance and productivity. Varieties Tercia, Novosibirskaya 89, Saratovskaya 68, Altaiskaya 60, Sonata (Russia); Dimitrovka 5-2, 5-18 Dimitrovka (Bulgaria); BW- 90 (Canada); Sp- 5679 (Czechoslovakia), showed a high resistance to leaf rust population of the Krasnoyarsk region, were used in the creation of new sources of resistance, that combine high productivity with other valuable agronomic traits.
