  1. 21. Codling moth, Cydia pomonella, antennal responses to Metschnikowia pulcherrima and Metschnikowia andauensis synthesised volatiles

    Master-uppsats, SLU/Plant Breeding and Biotechnology (until 121231)

    Författare :Tobias Lindblom; [2012]
    Nyckelord :Cydia pomonella; Codling moth ; Metschnikowia; yeast; volatiles ; GC EAD ; average; apple;

    Sammanfattning : Insect-yeast interactions have been known for decades but are poorly understood. To investigate the codling moth (Cydia pomonella ) olfactory connection to yeasts, volatiles from two ascomycete yeasts, Metschnikowia pulcherrima and Metschnikowia andauensis, were analysed using gas chromatography combined with electroantennographic detection (GC-EAD).

  3. 22. Pheromone-based monitoring of Elater ferrugineus as an indicator for species-rich hollow oak stands

    Master-uppsats, SLU/Plant Breeding and Biotechnology (until 121231)

    Författare :Klas Andersson; [2012]
    Nyckelord :Elater ferrugineus; Osmoderma eremita ; saproxylic; indicator ; Quercus sp. ; pheromones; conservation;

    Sammanfattning : The rare beetle Elater ferrugineus was sampled at 47 sites in the county of Östergötland, Sweden by means of pheromone-baited traps to assess its value as an indicator species for hollow oak stands rich in rare saproxylic beetle species. In addition Osmoderma eremita was sampled with the same method. LÄS MER

  4. 23. Microsatellite marker-based genetic diversity analysis and developing synthetic varieties in Alfalfa (Medicago sativa L.)

    Master-uppsats, SLU/Plant Breeding and Biotechnology (until 121231)

    Författare :Maksatbek Amanov; [2012]
    Nyckelord :Alfalfa; genetic diversity; Kyrgyzstan; microsatellite; SSR; synthetic variety;

    Sammanfattning : Cultivated alfalfa (Medicago sativa L.) is an allogamous autotetraploid species with 2n = 4x = 32 chromosomes. Alfalfa is the most cultivated forage legume in the world mainly due to its wide adaptation to diverse environmental conditions and efficient nitrogen fixation ability. Kyrgyzstan is among the major alfalfa producing countries. LÄS MER

  5. 24. Study on the on-farm diversity of local date palm (Phoenix dactylifera L.) genetic resources grown in Northern region of Sudan

    Master-uppsats, SLU/Plant Breeding and Biotechnology (until 121231)

    Författare :Mohammed Elsafi; [2012]
    Nyckelord :Date palm; River Nile RN ; Northern State N ; morphological characterisation; molecular marker; Simple sequences repeat marker; SSR; genetic diversity;

    Sammanfattning : The status of the conservation of the date palm genetic resources (Phoenix dactylifera L.) in the Northern region of Sudan was assessed through morphological characterisation of mature trees on farm, by conducting interviewing farmers and by molecular analysis of samples collected from the field.

  7. 25. Isolation and evaluation of different wheat-rye translocation lines obtained from a disease resistant double translocation line with 1BL/1RS and 2RL/2BS

    Master-uppsats, SLU/Plant Breeding and Biotechnology (until 121231)

    Författare :Mahbubjon Rahmatov; [2012]
    Nyckelord :C-banding; coleoptile colour; resistance; Simple Sequence Repeats; stem rust; translocation; wheat-rye; yellow rust;

    Sammanfattning : Wheat-rye translocations involving 1RS and 2RL of rye are the most useful sources of genes for disease resistance in wheat breeding. Rye genes are known to control resistance to biotic and abiotic stresses. LÄS MER
