    Sammanfattning : A structured breeding program is an important step towards sustainable tilapia aquaculture in Tanzania. The aim of the thesis was to generate baseline information for the establishment of tilapia breeding program in Tanzania. LÄS MER

  3. 2. Breeding for improved hip and elbow health in Swedish dogs

    Författare :Sofia Malm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Decades of selective breeding to reduce the prevalence of hip and elbow dysplasia(HD and ED) in Swedish dogs, based on phenotypic assessment of radiographic hip status, has had limited success. The prevalence of dysplastic dogs is still high in many large-sized and giant breeds and among the most common causes for euthanasia and costly veterinary care in numerous breeds are joint-related problems.

    Författare :Wouter Visch; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biofouling; cryopreservation; ecosystem services; environmental impact; extractive aquaculture; gametophytes; kelp; population diversity; Saccharina latissima; seaweed cultivation; selective breeding; site selection;

    Sammanfattning : Seaweed aquaculture is gaining more interest worldwide, including Europe. However, despite its long coast seaweed farming is still very minor in Sweden. LÄS MER

  5. 4. Genomics of heterosis and egg production in White Leghorns

    Författare :Esinam Amuzu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Crossbreeding  is  practiced  extensively  in  commercial  breeding  programs  of many  plant and animal species, in order to exploit heterosis, breed complementarity, and  to  protect  pure  line  genetic  material.  The  success  of  commercial  crossbreeding  schemes depends on identifying and using the right combination of breeds, lines or  varieties  that  produce  the  desired  crossbred  offspring.

  7. 5. Quantitative genetics of wood quality traits in Scots pine

    Författare :Irena Fundová; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Wood quality of commercial tree species is important for many wood processingindustries and thus should be considered for inclusion in forest tree improvementprograms. This thesis evaluated the suitability of various proxy methods for rapid andnon-destructive assessment of wood quality traits on standing trees of Scots pine and thepotential for genetic improvement of different wood quality traits through recurrentselective breeding.
