    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:
    Leaf rust is economically important disease of barley in many barley growing countries including Poland. A total of 25 winter barley cultivars and breeding lines were tested for leaf rust resistance with eight differential isolates. These isolates originated from IHAR Radzików collection and were chosen according to their virulence spectra. Among 25 cultivars and breeding lines only 7 (28%) showed resistance reaction after inoculation with at least one isolate of P. hordei...

    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:
    Since 1967, over 2,500 rye (Secale cereale L. and S. montanum Guss.) populations have been studied at the N.I.Vavilov Research Institute of Plant Industry in order to determine genetic diversity of the crop with respect to leaf rust (Puccinia recondita Rob.) resistance. Plants possessing race-specific resistance to leaf rust were found in 51 accessions (cultivars, landraces and wild species). In 2000, a study of 420 rye accessions revealed stem rust (Puccinia graminis Pers. f. sp. secalis Erikss. et Henn.) resistant genotypes in 69 of them. Control of leaf rust resistance was found to be dominant monogenic in 44 accessions, and digenic in cultivar Chulpan 2. In some accessions, e.g. Avangard 2, Novozybkovskaya 4-2 and Derzhavinskaya 2, leaf rust resistance of individual plants was determined by one dominant gene, while in other plants of the same accessions it was determined by two dominant genes. In most resistance sources (Sanim, Chernigovskaya 3, Kharkovskaya 55) genetic control of the character is determined by the Lr4 gene, in Jmmunnaya 1 by Lr5, in Chulpan 3 and Immunnaya 4 by Lr6, in Novozybkovskaya 4-2 by Lr7, and in Lovaszpatonai by Lr8, in Yaroslavna 3 by LriO. Stem rust resistance is controlled by the dominant gene Sri. By pyramiding effective resistance genes two new winter rye cultivars have been bred.These are Estafeta Tatarstana (1999) and Era (2001) characterized by a high-level resistance to leaf and stem rust, to powdery mildew.
