Abstract
The purpose of research is to identify the most adaptive and productive varieties of potatoes for the steppe zone of Southern Urals. The experience was laid by one-factor circuit in 3-fold repetition. The studies were conducted for middle- and middle-early varieties of potatoes domestic and foreign selection. Determined yield, marketability, starch and dry content in potato tubers. At 4 years of data were allocated potato varieties – Artemis (57.8 t/ha), Aerrow (52.0 t/ha) and Romano (49.5 t/ha). Distinguished highest yield of marketable products varieties: Artemis – 97.9%, Tarasov – 97.7%, and Aerrow Romano – 97.4%. The starch content in tubers was measurable by 10.2% (Ed Scarlett) to 16.0% (Kovalenko Memory), and the dry matter content in tubers ranged from 15.6% (Ed Scarlett) to 23.8% (Memory Kovalenko).
