- 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.
