Abstract Results of investigations on domestic and foreign varieties of potatoes early in the Right–Bank Forest–Steppe of Ukraine. Growing potatoes is impossible without the use of high-yielding varieties. Variety plays a crucial role in the production of products. It is share in the gross production of potatoes for 30 to 50%. It is share in the gross production of potatoes for 30 to 50%. Using the best varieties – one of the most effective means of increasing the yield of potatoes and improving product quality. Under production conditions deteriorate and need variety strain renovation. For high yields of potatoes early-ripening must first select the right variety, from where you can get not only high, but also a healthy crop. It is proved that a large area of leaves during flowering was observed in grade Carrera and Latona, which amounted to 31,4 and 31,1 thousand m2/ha, respectively, compared with controls yielded a significant increase of 7,6 and 7,3 thou-sand m2/ha, respectively. Found that the number of stems close to the control plants formed a sort Fun – 146,9 thou- sand pcs./ha. Varieties of Latona and Carrera, this indicator was 224,5 thousand pcs/ha and significantly exceeded the control by 85,8 thousand pcs/ha. Proved that getting high early potato crop in the Right–Bank Forest–Steppe of Ukraine on black soilpossible through the use of adapted varieties of foreign selection Latona, Bellarosa and Red Scarlet, allowing to obtain additional 10,3–14,1 tons/ha. The relationship between the features of the passage of potato plants phonological phases of growth and development, biometric performance and yield, depending on the variety.
