  2. 1. Selection, Maternal Effects and Inbreeding in Reindeer Husbandry

    Author : Lars Rönnegård; Högskolan Dalarna; []
    Keywords : breeding programme; communal grazing; randombred populations; Rangifer tarandus tarandus; semidomestic reindeer; gene flow; reindeer; animal breeding; gene flow; random mating; breeding methods; genetic inheritance; population structure; extensive husbandry; sweden;

    Abstract : In extensive grazing systems where several owners’ flocks are allowed to mix, selection strategies will also interact, due to gene flow between flocks. The aim of the thesis was to analyse breeding schemes in terms of genetic gain and rate of inbreeding (?F), given the complexity of ownership and interaction of selection strategies within a mixing reindeer population.

  4. 2. Novel Methods for Resistance Breeding in Winter Wheat

    Author : Mustafa Zakieh; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Breeding for disease resistance in winter wheat is a critical task in the agricultural industry, as plant diseases can significantly impact crop yield and quality. Traditional breeding methods are time-consuming, and disease resistance screenings are often cost and labour-demanding. READ MORE

  5. 3. Advancing red clover breeding through genomic selection methods

    Author : Johanna Osterman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Red clover is a major forage legume and a highly valuable crop for Northern Europe due to its high protein value and multiple ecological services. It is an important crop for both the ruminant industry and ecological farming. As growing conditions change due to rapid climate change, the demand for red clover breeding has increased. READ MORE

  6. 4. Novel methods for improved tree breeding

    Author : Jon Hallander; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The development and implementation of statistical tools to improve inference in sustainable forest tree breeding are presented here. By combining classical quantitative genetic theory and novel statistical methods, a number of parameters are optimized. READ MORE

  7. 5. On starlings and farming: population decline, foraging strategies, cost of reproduction and breeding success

    Author : Måns Bruun; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; breeding success; foraging strategies; intensification; agricultural methods; population decline; farmland bird; cost of reproduction; Animal ecology; Djurekologi;

    Abstract : The European Starling Sturnus vulgaris as many other farmland bird species has been declining during the last decades. The cause of these declines is generally believed to be changes with in agricultural methods affecting breeding and survival of birds. READ MORE
