The experiment was performed in the Maritsa Vegetable Crops Research Institute, Plovdiv and Experimental station, Samokov during the period 2009-2011. The aim of this study was to evaluate the adaptability and stability of standard yield in production of certified seeds from four Bulgarian potato varieties. Three factors field experiment was set with 12 combinations to established effect of the factors - fertilization rate, planting density and term of leaf striping on the standard yield of the seed fractions in varieties Rozhen, Perun, Kalina and Bor. It was established that varieties Bor, Perun and Kalina are described with a complex value, combining high level, relatively stability and adaptability of standard yield in change of the environmental conditions in the variant including higher level of nitrogen and potassium fertilization, higher planting density and earlier term of leaf striping. High level of stability and adaptability, but lower productivity is recorded in variety Rozhen in the variant including fertilization rate N16 P14 K18, higher planting density and later term of leaf striping
