Twenty-five AFLPs, previously linked to fertility restoration genes for the male-sterilizing PAMPA cytoplasm (cms-P) in a restricted rye population, were studied in an enlarged population of 120 plants. A strong association with the trait was verified for 19 of the markers. The recombination of these markers was tested and two linkage groups were identified: one consisting of six and the other of eight AFLPs. The remaining markers were segregated as independent loci. Using wheat-rye addition and substitution lines, the AFLPs were assigned to individual rye chromosomes. AFLP profiles of such lines were generated to identify the DNA fragments co-migrating with individual markers. This identified 1R and 3 R as the two chromosomes corresponding to the linkage groups of eight and six markers, respectively. Mapping in a DS2 x RXL10 population linked four additional AFLPs to chromosome arms 1RS, 3RL, 4RL and 6RL. RAPD and SSR markers mapped in various populations and known to be located on the appropriate chromosomes did not disrupt the C394-F2 population into sterile and fertile phenotypes. It was concluded that the identified markers would reduce by one half the number of primer pair combinations needed for molecular breeding programs or for the selection of parental forms for rye hybrid crosses.

Transmission of added and substituted rye chromosomes through generations and behavior of chromosomes at meiosis was analyzed. Among the addition lines, chromosome 7R was most often transmitted and 6R most rarely. In substitution line 1B/1R, no elimination of rye chromosomes was observed in any generation. The tested lines differed from wheat in the behavior of chromosomes at meiosis. The rye and wheat chromosomes interacted during meiosis. The added rye chromosomes influenced bivalent shape and univalent frequency at metaphase I, the number of delayed chromosomes and chromatid bridges at anaphase I, and the occurrence of micronuclei in tetrads. In the majority of lines the frequency of open bivalents and univalents was higher than in ‘Grana’ wheat and ‘Dańkowskie Złote’ rye. Rye chromosomes occurred more frequently as univalents than wheat chromosomes did. Neither multivalent associations nor homoeologous pairing were observed. The studied lines had good cytogenetic stability.

Oceniano reakcję linii addycyjnych i linii substytucyjnej 1B/1R oraz form wyjściowych, tj. pszenicy, żyta i pszenżyta oktoploidalnego na działanie kwasu giberelinowego (GA3). Test giberelinowy przeprowadzono w komorze wegetacyjnej w warunkach kontrolowanych. Siewki podlewano roztworem gibereliny o stężeniu 50 mg/g przez 18 dni, po czym mierzono długość koleoptyla i całą siewkę. Badane linie różniły się między sobą i od pszenicy pod względem reakcji na GA3. Najdłuższą siewkę i koleoptyl stwierdzono w linii addycyjnej 2R. Na podstawie uzyskanych wyników można wnioskować, że na chromosomie 2R żyta odmiany Dańkowskie Złote znajdują się geny kontrolujące metabolizm związany z wykorzystaniem giberelin.
