Unit of Genetics and Breeding

Activity goals and directions:

• Breeding of cultivars that are adapted to the agro-climatic conditions of the Baltic Sea region, breeding of cultivars of primary fruit crop culture (apples, raspberries, Chaenomeles japonica, black currants) that are highly resistant or immune to pests and diseases
• The coordination of the conservation, documentation and research on horticultural crop genetic resources, research on genetic resources using molecular markers, evaluation of genetic diversity.
• Genetic resource characterisation, genotyping, diversity analysis and use for cultivar diversification and breeding of horticultural crops.
• The development of scientific and theoretical basis for research on fruit crop heredity mechanisms and characterisation of breeding material by applying molecular genetics methods.
• The development of scientific and theoretical basis for introduction of molecular genetics methods in breeding, the development and application of economically significant characteristic identification methods in breeding.
