Opis:: The Czech winter wheat cv. Regina which does not possess specific genes for powdery mildew resistance except Pm5 was crossed with the cvs. Florida, Tjelvar, Agra, Olymp and Sabina, all possessing T1BL-1RS and the dominant suppressor SuPm8, with Riebesel 47/51 possessing substitution 1R-1B and SuPm8 and with the T1BL-1RS cvs. Sparta, Iris, Mona without SuPm8. Powdery mildew isolates avirulent on Pm8 and virulent on other Pm genes were used in the trials. Tests for resistance were carried out either on seedlings at the first leaf stage or on detached leaves cultured on benzimidazolagar. No segregation for resistant plants in F₂ of all crosses of the cv. Regina with cultivars possessing T1BL-1RS and SuPm8 indicates that Regina has SuPm8. The segregation ratio 3 resistant: 13 susceptible in the F₂ population of crosses between the cv. Regina and cultivars possessing T1BL-1RS and no SuPm8 also confirms the presence of SuPm8 in the cv. Regina. The obtained results also indicate that expression of Pm2 and Pm4b is not affected by SuPm8 and that SuPm8 does not affect stem rust resistance gene Sr31 located on 1RS segment.

Opis:: A total of 67 barley cultivars and breeding lines were tested for leaf rust resistance were tested with eight differential isolates. These isolates originated from IHAR Radzików collection and were chosen according to their virulence spectra. Among 67 cultivars and breeding lines 41 (61%) showed resistance reaction after inoculation with at least one isolate of leaf rust. In 29 cultivars and breeding lines (43.2%) the presence of specific resistance alleles was postulated.

Opis:: There were performed tests on a set of twenty single substitutions of the D-genome chromosomes from various bread wheats into winter triticale Presto, a set of seven disomic addition lines of chromosomes from winter rye Dańkowskie Zlote to winter wheat Grana, and all parental forms to study on the chromosome location of major genes that are resposible for seedling stage resistance to Puccinia recondita f.sp.tritici in triticale. For each line, seedlings developed to two-leaf stage were exposured to four pathotypes of the pathogen predominant in Poland to test them in the greenhouse conditions. There were high resistance among the substitution lines of Presto, 1D(1A), 4D(4R), and 5D(5R) suggesting that chromosomes introduced from the D-genome carried resistance genes. Among the addition lines, GH2R was highly resistant. Resistance to rust at seedlings stage of Presto lines of D- genome and addition lines Grana (wheat) / Dankowskie Zlote (rye) shows that chromosome 2R is responsible for the resistance to the disease.

Opis:: Economically important rye (Secale cereale L.) cultivars are highly susceptible to leaf rust caused by Puccinia recondita f.sp. secalis in Germany. Presently, only race-specific resistances are available, which are likely to lose their effect after prolonged application. To study possibilities of increasing the durability of resistance, a three-year field experiment was initiated in 2000. Seventeen differential lines, three susceptible standards, 30 segregating populations with one to four resistance sources and two full-sib families were grown at six locations under a high level of natural infection. All segregating populations were significantly more resistant than the susceptible standards. The resistance level, however, was under these conditions moderate only. The two full-sib families from Russia showed high resistance. Strong genotype × location interactions were observed indicating different race compositions of the local leaf rust populations.

Opis:: Leaf rust caused by fungus Puccinia hordei has great economic importance in many barley growing regions in Europe, North America, Australia and West Asia and North Africa. Bulbous barley grass (Hordeum bulbosum L.), is the only member of the secondary barley genepool. In presented study 6 recombinant lines obtained from backcrosses of barley cultivars (backcrossing parents) and accessions of H. bulbosum were tested with 8 differential isolates of leaf rust. This study showed that resistance to leaf rust is present in 5 from total 6 recombinant lines. Outstanding resistance to leaf rust was identified in line 886Z3/1/10/1/2/1, which showed resistance reaction 0 for inoculation with all isolates used...
