Utilization and application of resistances of not adapted PGR for potato breeding by use of biotechnological methods.
Project
Project code: JKI-ZL-08-0063
Contract period: 01.01.2009
- 31.10.2021
Purpose of research: Applied research
Wild potato species are a valuable genetic resource for broadening the genetic diversity of cultivated potato. Therefore gene bank accessions of wild species with sexual incompatibility to cultivated potato which are not utilized in potato breeding are interesting. Accessions with high level of resistance to Phytophthora infestans (Mont.) de Bary, resistance to PVY and PLRV, aphids, and resistance to Colorado potato beetle are used. Somatic hybrids are produced between wild species of the genus Solanum, series Bulbocastana, Commersoniana, Etuberosa and Pinnatisecta and the cultivated potato. The aim of the project is to create new somatic hybrids, to select genotypes with high level of resistance to late blight, virus diseases and Colorado potato beetle and carry out backcrosses with cultivated potato. Breeding material is generated for utilization in potato breeding programs. Based on genetic analyses the mode of inheritance of selected pathogen resistances will be determined. Linked genes will be mapped and selective markers for potato breeding should be developed.
Interspecific somatic hybrids of potato were selected with resistance to potato viruses, foliage blight, Colorado potato beetle and aphids. The hybrids were crossed with cultivated potato. Breeding material is generated for utilization in potato breeding programs. Based on genetic analyses the mode of inheritance of selected pathogen resistances will be determined.
