The public defense of the EMU Institute of Agricultural and Environmental Sciences doctoral student Marje Särekanno´s PhD thesis «Analysis Of Productivity Indicators Of Field Grown Potatoe Meristem Plants Multiplied By Different Methods» takes place on Monday, December 19.

Särekanno researched the productivity indicators of potatoe plants multiplied by different methods. She focused on plants of eradicated disease-free initial seed production material, as obtaining disease-free high yield potato plants from infected potato varieties is an important precondition to the whole potatoe farming industry and as this field has been relatively unresearched until today.

She observed potatoe plants of four different multiplication methods growing on a field in Saku for two years. She measured the dynamics of potatoe growth and analyzed samples gathered from the fields. It was concluded that the plants multiplied from in vitro micro-cuttings, i.e in lab conditions had smaller tubers than plants multiplied by different methods.

The supervisors of the thesis are Dr. Katrin Kotkas and Dr. Evelin Loit. The opponent of the thesis is Dr. Ramona Thieme (Institute for Breeding Research on Agricultural Crops, Federal Research Centre for Cultivated Plants, Julius Kühn-Institute, Germany). The thesis is available in the EMU and TU Libraries.
