" Innoving for the quality of certified seed potatoes "


FN3PT, the technical institute of the seed potato sector, is leading with its regional organizations important actions of research and development in order to develop the innovation, to anticipate the evolutions of the sector as well as to strengthen the quality and the competitiveness of the French seed sector.
The strategic objectives of R&D actions of the seed potato sector are to strenghen the quality and the competitiveness of the seed potato production in France in a prospect of sustainable development.

The program focus on three research priorities:

  1. Healthy certified seed potatoes:

Preserving and insuring the health of seed potatoes is a key point for growers and users. Different research programmes are conducted on this subject in order to :

1-to strengthen the sanitary guarantees on the certified seed tubers
2-to protect the production area from the development of new diseases,
3-to reduce the non-quality causes by improving the knowledge on pests and diseases
4-to develop and to transfer innovations and new techniques of detection, monitoring and control of potato diseases of plants in a context of reduced use of pesticides.
The main research fields concern the improvement of the techniques for the detection of potato diseases ( viruses, bacteria and nematodes) on plants and in its environment, the epidemiology of emergent diseases (sources of inoculum, development factors,..) as well as the search for innovative methods for their control and prevention.

  2. Genetics and varietal innovation:


Research programmes are driven to support the breeding of new potato cultivars, which are adapted to the various market sectors and combining multiple criteria (productivity, precocity, capacity in the mechanization, quality of tubers presentation , cooking and processing qualities , adaptation to pedoclimatic zones, etc.).

In a context of limitation of inputs, research is focused on the creation of varieties presenting resistance to diseases. Programmes are oriented on a better characterization of the genetic resources and on the development of molecular tools and strategies to speed up the introgression of candidate genes, in particular genes linked to the resistances against the main potato diseases (nematodes, late blight, virus etc.).

 3. Developing innovative strategies for seed potato production:


Applied research is operated in the regional seed potato centres and with farmers in order to develop, to evaluate and to transfer innovations for the production and protection of seed potato crops. (plantation, fertilization, irrigation, crop protection, harvesting, storage, etc.).
