    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:
    Two sets of disomic substitution lines, derived from the cultivars ‘Presto’ and ‘Rhino’ of triticale, with rye chromosome pairs replaced by their wheat D-genome homoeologues, were tested in hydroponic culture. The size of root system (dry matter, length, number of seminal and adventitious roots) was investigated together with total plant dry matter. The results were influenced mainly by the growth stage and interaction between homoeology group of exchanged chromosomes and varietal background. In relation to the controls (unchanged cultivars), only the ‘Rhino’ 2D(2R) showed a significant increase of plant dry matter. No significant negative effect on plant mass was stated for the 3D(3R) in ‘Presto’ and the both 1D(1R) substitutions. Tolerance of the 4D(4R), and 5D(5R) disomic substitutions was poor; 7D(7R) was absent as not able to survive. The majority of changes noticed for the root system parameters were parallel to the changes in plant dry matter. Besides, some effects specific to root system were found in adult plants. Relationships are discussed between the obtained results and the earlier ones on disomic rye additions to hexaploid wheat.

    Opis:
    The aim of paper was evaluation of composition of high molecular weight (HMW) and low molecular weight (LMW) glutenin subunits in wheat-rye addition lines cv. Grana - cv. Dańkowskie Złote, substitution line 1B/1R and initial forms, as well as, localization of Sec genes on chromosomes ‘Dańkowskie Złote’ rye. Analysis were performed using SDS-PAGE electrophoresis.The composition of HMW glutenin for all addition lines and ‘Grana’ wheat was: N - 6+8 - 2+12. Composition of LMW glutenin was estimated only for 2R and 6RL addition lines, wheat, and octoploid triticale. In both addition lines the subunits N-6+9-15 were identified, in wheat cv. Grana subunits 1-6+9-15 were present, whereas in octoploid triticale polymorphism was observed (1-6+9-15 or 1-11+13-N). Rye storage proteins (secalins) was found in addition lines: 1R, 2R and substitution line 1B/1R. It can be concluded that genes responsible for secalin biosynthesis in rye cv. Dańkowskie Złote are localized on 1R and 2R chromosomes.
