Webinar organized by the World Potato Congress will discuss an alternative to minitubers as starter material for seed production

Addressing seed shortages for potato is a perennial challenge in many potato-producing countries. Potato seed systems rely on several successive generations of bulking seed tubers to produce commercial seed, with multiplication ratios averaging 1:10-15 for each generation, compared to 1:200 for true seed crops.

As a consequence of these low multiplication ratios, three to four successive seasons in the field are required to produce commercial seed that is economically viable for the seed producer to sell and the farmer purchasing seed. Critical to seed potato production is the starter material used for onward multiplication. Traditionally, minitubers produced from tissue culture plants using soil-, hydroponic- or aeroponic-based systems in a screenhouse serve as starter material for onward bulking in the field. Apical cuttings are an alternative to minitubers as starter material for seed production.

The speaker of this webinar will be Dr. Monica Parker (see bio below). The host for the webinar series will be WPC Director, Dr. Nora Olsen ([email protected]).
