1. Application of Molecular Markers in Sugar Beet Breeding
Sammanfattning : Around 1750 a German chemist discovered it to be possible to extract sugar crystals from beet juice. Since then, breeding and improved agricultural practices have increased the concentration of sucrose per root from around 4% to around 18%. LÄS MER
2. Selection, Maternal Effects and Inbreeding in Reindeer Husbandry
Sammanfattning : 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.

3. Genomic-led potato breeding
Sammanfattning : Most cultivated potatoes (Solanum tuberosum L.) are polyploids with tetrasomic inheritance (2n = 4x = 48), which makes breeding for new improved cultivars more complicated compared to diploid crops. LÄS MER
4. Barley genetic resources for Kyrgyz plant breeding
Sammanfattning : Barley (Hordeum vulgare L.) is one of the most important forage cereal crops in Kyrgyzstan. Today it is grown under extremely hard conditions in many highland regions where other crops cannot compete. Kyrgyzstan is a mountain agrarian country and agriculture is one of the major sectors of the economy. LÄS MER
5. Cooperative Breeding in the Southern Anteater-Chat : Sexual Disparity, Survival and Dispersal
Sammanfattning : Group-living sets the scene for complex social behaviours such as cooperative breeding, and exploring the factors that shape group-living is crucial in understanding these behaviours. This thesis explores the ecology of a population of the facultative cooperative breeding southern anteater-chat (Myrmecocichla formicivora), a group-living bird species endemic to southern Africa.
