Title	Resistance of some winter triticale varieties to leaf rust (Puccinia recondita f. sp. tritici)

Abstract	To determine whether the resistance to leaf rust (Puccinia recondita f.sp. tritici (Puccinia hordei)) of the winter triticale cultivars Presto, Vero and Ugo is controlled by the same genes, crossing of these cultivars was performed. The parental forms, F1 and F2 generations were tested at the seedling stage in a greenhouse and at the adult plant stage under field conditions (Poland) using the isolate 65a/95 of P. recondita f.sp. tritici. The infection in a greenhouse was scored after 14 days, while that under field conditions was estimated 2 and 4 weeks following inoculation. The results of testing parental forms and F1 and F2 generations, both at the stage of seedling in a greenhouse and in adult plant in the field, indicated that the F1 and F2 generations showed resistance similar to that of resistant parents. It can be inferred that resistance of Presto, Vero and Ugo to leaf rust isolate 65a/95 is controlled by the genes of the same action
