Somatic hybridization in potato breeding

Popis výsledku v původním jazyce

Somatic hybridization is an alternative method for creating new breeding materials. In our work, this method was applied in two directions, for both intraspecific and interspecific hybridization. To combine the ability of a good yield and capability for industrial processing, dihaploids of Solanum tuberosum were used. To enrich Solanum tuberosum by resistance genes, Solanum pinnatisectumand S. bulbocastanum were employed. Both wild species are tuber-bearing diploids with high level of resistance to Phytophthora infestans. Progeny was obtained from each combination. While the somatic hybrids of S. pinnatisectum + S. tuberosum and somatic hybrids of dihaploids S. tuberosum flowered sufficiently and their sexual offspring was obtained, the somatic hybrids of S. bulbocastanum + S. tuberosum bloomed rarely and sexual progeny has not been gained yet. Somatic hybrids S. pinnatisectum + S. tuberosum and some individuals of their progeny displayed moderate or high level of resistance to P. infestans in laboratory tests and also in the field experiment. This work demonstrated the possibility of somatic hybrids to be sexually crossed with S. tuberosum cultivars, and also proved the opportunity to pass resistance to P. infestans from wild species to somatic hybrids and also to cross generation.
