  1. 1. Genotypic and phenotypic variation of Phytopthora infestans on potato in the two Swedish regions Bjäre and Östergötland in 2015

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Ida Peterson; [2015]
    Nyckelord :potato late blight; mating type; simple sequence repeat markers SSR ; microsatellites; Multiplex PCR; sexual reproduction; asexual reproduction; aggressiveness; tests; population study;

    Sammanfattning : Potato late blight, caused by the oomycete Phytophthora infestans, is a very im-portant disease on potato, and one of the most devastating plant diseases in agri-culture worldwide. Despite the small area of potato in comparison with other cul-tivated crops, 40 % of the total use of fungicides in Sweden is used on potato. LÄS MER

  3. 2. Has modern Swedish forestry affected genetic diversity in Norway spruce stands?

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Helena Dahlberg; [2015]
    Nyckelord :Picea abies; genetic differentiation; age groups; nuclear microsatellites; forestry;

    Sammanfattning : Norway spruce is one of two dominating species in Swedish forestry and the most economically important tree species in Sweden. In order to preserve the ability to adapt to a changing environment and to keep populations healthy, genetic diversity has to be preserved. LÄS MER

  4. 3. Genetic diversity of local maize (Zea mays L.) germplasm from eight agro-ecological zones in Mozambique

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Abilio Virissimo Afonso; [2013]
    Nyckelord :Genetic diversity; maize; Zea mays; germplasm; agro-ecological zone; Mozambique; Simple Sequence Repeat SSR ;

    Sammanfattning : The genetic diversity within and among 27 accessions of local maize maintained at the National Gene bank of Mozambique was studied. The accessions were originally collected from farmers’ fields in 8 of the 10 agro-ecological zones of Mozambique. Eleven SSR markers were used. A total of 84 alleles were found with an average of 7.

  5. 4. 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

  7. 5. Genetic diversity of Roseroot (Rhodiola rosea L.) from Sweden, Greenland and Faroe Islands

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

    Författare :Madeleine Kylin; [2010]
    Nyckelord :Rhodiola rosea; Roseroot; genetic diversity; microsatellites; inter-simple sequence repeat;

    Sammanfattning : Roseroot (R. rosea L.) has gained more attention the last years, mainly because of its phy-topharmacologic properties. Even though many reports in roseroot have been published, only a few articles are dealt with the genetic diversity. LÄS MER
