The producers of the cooperative produce their own seed potato from the first generations which are Pre-Elite and Elite 1. Once planted, the potatoes join the following generation. For example, a potato who have been planted Elite 1 will be harvested Elite 2. It takes about two or three years for a variety before being marketed. A board of those generations which is called “Class” is presented below :

La Patate Lac-Saint-Jean markets in majority varieties of Class Elite 3 and Elite 4. It’s important to note that the designations of  the generations may be different from a country to another, and sometimes, from a state to another.

Otherwise, a business within the cooperative, the Farm Daniel Bolduc et fils inc., possesses facilities as well as expertise for the  production of seed potatoes of Class Nuclear. Plantlets In vitro are preserved and multiplied in aseptic environment. Laboratory tests are done regularly on those plants to confirm the absence of viruses and bacterias. Those plantlets are cutted and may serve to the hydroponic production of mini-tubers. This culture without soil permit to get safe seeds of specific size. The safety during the production is constantly evaluated by Canadian Food Inspection Agency who certified the different steps of production.
