    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.

    Sammanfattning : The final objective of tree improvement programs is to increase the frequency of favourable alleles in a population, for the traits of interest within the breeding programs. To achieve this, it is crucial to decompose the phenotypic variance accurately into its genetic and environmental components in order to obtain a precise estimation of genetic parameters and to increase genetic gains.

    Sammanfattning : Sesame (Sesamum indicum L., Pedaliaceae) is a traditional oil crop cultivated in Vietnam and Cambodia. It is known as the king of oil seeds in Vietnam due to the high oil content (50-60%) in its seed. LÄS MER

  5. 14. Towards a sustainable tilapia breeding program in Tanzania

    Sammanfattning : Bread wheat (Triticum aestivum L., 2n = 6x = 42, AABBDD) is one of the most important food crops world-wide, but is attacked by many diseases and pests that cause significant yield losses. Globally, stem rust (Sr) (Puccinia graminis f. sp. LÄS MER
