Potato seed systems that exist today consists of five seeds classes, namely G0, G1, G2, G3, and G4. G0 to G3 seed is the source seed, while classes G4 seed was extension seed. Many breeders, farmers and other stakeholders argue that the process of seed production from G0 to G3 class was too long so that the supply of potatoes seeds for consumption (G4) could not be carried out faster. Research was conducted to determine the level of productivity of each class of potato seed G0 to G4 to be recommended as a seed class for potato consumption. The reseach was conducted at Margahayu Experimental Garden of Indonesian Vegetable Research Institute Lembang from September–November 2012 in randomized block design with six treatments : seed class (G0, G1, G2, G3, G4, and control) with four replications. The parameters observed were plant growth, production, and product quality. Hence, it can be concluded that potatoes derived from G3 class was quite suitable for extension seeds. The higher the seed class (G0 and G1) the higher the increasing rate and it produced higher number of C and D tuber grade.
