  1. 1. Screening of early root growth characteristics in seedlings of Nordic spring barley : utilization of hydroponics and GWAS for identification of QTLs and candidate genes for root traits

    Master-uppsats, SLU/Dept. Of Plant Breeding

    Författare :Karl-Johan Fabo; [2021]
    Nyckelord :spring barley; plant breeding; root growth; early vigor; seminor roots; GWAS; QTL; quantitative traits; quantitative genetics; marker-assisted breeding; hydroponics;

    Sammanfattning : In the Nordic countries, the cultivation of barley (Hordeum vulgare L.) has a long history, and as one of the major cereals in the world, barley is of global importance for food security. The world population is growing, which naturally will increase demands for agricultural outputs. LÄS MER

  3. 2. Studying genetics of leaf shape variation in Arabidopsis lyrata

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

    Författare :Carina Kvernes Macpherson; [2019]
    Nyckelord :Arabidopsis lyrata; Arabidopsis arenosa; leaf shape; RCO genes; genotype; phenotype; gene sequence variation;

    Sammanfattning : The relationship between leaf and its environment has resulted in a tremendous diversification of leaf shape within and between plants species, which is important to cope with the differing environmental conditions. Arabidopsis lyrata is a prime model plant that shows leaf shape variation within species and between related species. LÄS MER

  4. 3. Genome wide association study of milk composition traits in Swedish Red cows

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Yohannes Goitom Tesfayonas; [2014]
    Nyckelord :Milk composition; single nucleotide polymorphism SNP ; GWAS;

    Sammanfattning : The aim of this study was to detect QTLs that affect milk composition traits such as fat yield, fat percent, citric acid, free fatty acids as well as milk properties like fat globule size, and determine the phenotypic variation explained by the QTLs. These traits play a crucial role in nutritional and technological properties of milk and its products. LÄS MER

  5. 4. Marker generation for Fine Mapping a QTL in the chicken

    Kandidat-uppsats, Linköpings universitet/Biologi; Linköpings universitet/Tekniska högskolan

    Författare :Ahlgren Elisabeth; [2014]
    Nyckelord :Behavior; Red Junglefowl; Single Nucleotide Polymorphism marker; Tonic immobility; White Leghorn; QTL analysis;

    Sammanfattning : The purpose of this study was to design and test five SNP markers in an inbred chicken cross between Red Junglefowl and domestic White Leghorn of the 8th generation. The markers lie in a region affecting the tonic immobility behaviour which differs significantly between the two species. LÄS MER

  7. 5. The genetic basis of a domestication trait in the chicken: mapping quantitative trait loci for plumage colour

    Master-uppsats, Biologi; Tekniska högskolan

    Författare :Md. Nazmul Huq; [2012]
    Nyckelord :qtl; quantitative trait loci; genome scan; qtl analysis; plumage colour; domestication trait; chicken; pigmentation trait;

    Sammanfattning : Domestication is the process by which animals become adapted to the environment provided by humans. The process of domestication has let to a number of correlated behavioural, morphological and physiological changes among many domesticated animal species. An example is the changes of plumage colour in the chicken. LÄS MER
